Overview

Games built to retain players, not just launch.

The gaming market reaches $435 billion by 2029, with over 3 billion active players globally. The barrier to launching a game is lower than ever — the barrier to retaining players is not. Most games lose 70–80% of Day-1 players before Day 7. Retention is an engineering problem, not a luck problem — determined by game-loop design, progression pacing, and monetisation integration that starts at the GDD stage, not post-launch.

We build games across Unity and Unreal Engine for mobile (iOS and Android), PC (Steam), and web — covering the full production pipeline: concept and GDD, 2D/3D art and animation, core gameplay engineering, physics, multiplayer netcode, monetisation (IAP, rewarded ads), backend LiveOps, QA, and store submission. We treat player retention and monetisation as design constraints, not afterthoughts.

We also build gamification systems for non-game products — adding mechanics like points, levels, achievements, streaks, and leaderboards to SaaS products, ecommerce, and mobile apps to increase engagement and retention.

4 game types we develop.

Each has a different engine choice, retention mechanic, and monetisation architecture.

Largest Market · 2026

Mobile Game Development

Mobile games generated $90.7 billion in 2025 — 52% of global gaming revenue. We build for iOS and Android simultaneously in Unity, the default for 2D and mid-complexity 3D mobile games. Mobile architecture differs from desktop in four ways: touch-only input, device fragmentation across hundreds of hardware tiers, thermal and battery constraints, and monetisation driven by ads and IAP rather than upfront sales. Every game we build is optimised for D1/D7/D30 retention from the GDD stage — progression, reward loops, and session design defined before code is written.

Premium Quality

PC Game Development

PC games — on Steam, Epic Games Store, or itch.io — allow broader creative scope, higher visual fidelity, and premium pricing models not viable on mobile. We build in Unity for 2D and indie-scale projects, and Unreal Engine 5 for projects requiring photorealistic visuals, large open worlds, or Lumen global illumination. PC development prioritises keyboard and controller input, higher polygon budgets, Steam Workshop integration, and achievements. Unreal’s Blueprints accelerate prototype iteration for non-engineering designers.

Multiplayer Game Development

Multiplayer games require three engineering layers beyond single-player: netcode (synchronising game state across clients with minimal latency), matchmaking (pairing players by skill, region, or criteria), and a scalable backend (handling CCU spikes during live events without downtime). We use Photon Fusion for Unity multiplayer and Unreal’s built-in online subsystem for Unreal projects. Anti-cheat, leaderboards, and tournament systems are standard inclusions in competitive builds.

Gamification Development

Gamification applies game mechanics — points, levels, achievements, badges, streaks, leaderboards, and reward systems — to non-game products to increase engagement, retention, and motivation. A SaaS productivity app that adds XP, level progression, and weekly challenges typically sees 30–40% increases in DAU and session length. We build gamification as modular backend services with an engine-agnostic API — connecting to mobile apps, web platforms, ecommerce, and learning management systems.

9 game development services we deliver.

Every production discipline — from concept to live game operations.

Game design & GDD

Concept development, core-loop design, player progression, game economy, difficulty curve, level-design framework, and a complete GDD — the single document that aligns designers, engineers, and artists throughout production.

2D & 3D art production

Character design and modelling, environment art, UI/UX for game interfaces, animation rigging (skeletal animation, Spine 2D for mobile), VFX (particle systems, shaders), and concept art — matching your target visual style.

Core gameplay engineering

Player movement, physics integration, collision systems, AI (pathfinding, FSMs, behaviour trees), game-state management, save systems, input handling across touch/keyboard/controller, and frame-rate optimisation for target devices.

Multiplayer & backend systems

Client-server multiplayer architecture, Photon Fusion or Mirror netcode, real-time matchmaking, leaderboards, player profiles, session management, and a CCU-scalable cloud backend on AWS or GCP — built for 10,000+ concurrent users from day one.

Monetisation & economy design

IAP integration (Apple StoreKit, Google Play Billing), ad-network SDK setup (AdMob, IronSource, Unity Ads, AppLovin), virtual-currency economy design, battle-pass systems, region-compliant loot mechanics, and ARPU optimisation.

LiveOps & post-launch support

Scheduled content updates, limited-time events, seasonal challenges, push-notification campaigns, A/B testing on economy variables, and DAU/retention dashboards. Games that run active LiveOps retain players 3–5× longer than static releases.

Game QA & playtesting

Functional QA across device tiers, platform compliance testing (App Store guidelines, Google Play policy), performance profiling (frame time, memory, thermal), crash-reporting integration, and structured playtesting to evaluate game feel and difficulty balance.

Store submission & ASO

Apple App Store and Google Play submission handling — screenshots, metadata, privacy labels, age-rating questionnaire, and ASO for title, keywords, and description to maximise organic visibility from day one.

Gamification for apps & SaaS

XP systems, achievement engines, streak tracking, leaderboards, challenge modules, and reward systems built as backend services — integrated into your existing mobile app, web platform, or SaaS product without a full game engine.

3 engines — how we choose the right one.

Engine selection determines build cost, visual ceiling, and platform compatibility. We recommend based on your genre, not preference.

Unity

Best for mobile games, 2D games, casual/mid-core titles, and cross-platform projects. The industry standard for mobile — 32% of all games use it. The Asset Store cuts cost on common systems; C# is approachable for smaller teams; one codebase targets iOS, Android, PC, console, WebGL, and VR. Unity Gaming Services adds matchmaking, leaderboards, economy, and remote config. URP targets mobile performance; HDRP targets high-end visuals.

Mobile · 2D/3D · C# · URP/HDRP

Unreal Engine 5

Best for PC games, console-quality visuals, photorealistic environments, and projects needing Lumen global illumination or Nanite virtualised geometry. UE5 delivers the highest visual fidelity in a game engine — Lumen handles real-time GI without baking, Nanite renders film-quality meshes at real-time frame rates. Blueprints let designers implement logic without C++. The 5% royalty applies only above $1M gross revenue — below that, it is free.

PC · AAA visuals · C++/Blueprints · Lumen

Godot 4

Best for 2D indie games, open-source projects, and teams that need zero licensing cost. Godot 4 uses GDScript (Python-like) or C#, is entirely free with no royalties, and is increasingly competitive for 2D. It is lighter-weight than Unity, so faster to prototype, but lacks Unity’s Asset Store depth and official mobile ad-network SDKs — so mobile monetisation needs more custom work. Right for 2D platformers, puzzle games, and indie PC titles where licensing cost matters.

BeesApp: a marketplace rebuilt with real-time systems and live data sync — the same engineering behind multiplayer game backends

Multiplayer game backends and real-time marketplace platforms share the same core challenges: concurrent users updating shared state, real-time data synchronisation across clients, low-latency APIs under variable load, and infrastructure that scales without downtime. We rebuilt BeesApp's entire platform — real-time inventory sync across vendors, live order tracking, concurrent session management — delivering 99.9% uptime and 74% faster load at 40% lower server cost. That real-time capability translates directly to game multiplayer backend architecture.

Why Build With Hoop

Games designed to retain players, not just ship.

Retention and monetisation decisions made in the GDD phase — not retrofitted post-launch when rewriting core systems is expensive and disruptive to active players.

  • 01

    Retention-first game design

    D1/D7/D30 retention targets are set at the GDD stage. Core loop, session length, progression pacing, and reward schedule are designed around specific benchmarks before engineering begins — not adjusted after the game ships and data shows 80% Day-1 drop-off.

  • 02

    Monetisation designed into the core loop

    Revenue systems layered onto an existing game without GDD-level planning create friction, harm reviews, and hurt discovery. We design monetisation as part of the economy from week one — IAP placement, rewarded-ad triggers, and currency sinks aligned with the natural gameplay flow.

  • 03

    Full-stack game development — one team

    Gameplay engineers, artists, UI/UX designers, backend engineers, and QA — all in one studio. No handoffs between separate art and code teams, no integration failures between a separately scoped multiplayer backend and the game client.

  • 04

    Software engineering depth

    Our game team comes from a software-engineering background — so game backends are architected properly, CI/CD pipelines run automated builds, APIs are versioned, and multiplayer servers auto-scale. Not all studios treat backend as a first-class engineering problem.

The Deep Dive

Understanding game development.

Direct answers to the questions asked most often before a game project — structured for citation by AI search and answer engines.

What is the game development process?

Game development follows five phases — pre-production, production, alpha, beta, and launch — with LiveOps continuing post-release. Pre-production defines the concept, core loop, target platform, engine, and GDD. Production builds the game in milestone-gated sprints. Alpha is the first complete but rough build, tested internally. Beta is feature-complete and tested more broadly, often via soft launch to collect real retention data. Launch is store submission and global availability. LiveOps — the ongoing content, events, and economy adjustments — is what separates games that retain players for 18 months from games that peak at week one.

Game development differs from standard software in three ways. Physics and rendering performance: a game must hold 30–60 FPS consistently, requiring constant CPU/GPU frame-time profiling. Feel and fun are non-functional requirements that user stories cannot capture — playtesting is the only way to validate a mechanic. Retention loops are systems built specifically to bring players back — daily rewards, progression gates, social competition — that standard products do not have. Getting these right needs game-design expertise, not just general engineering.

What is a GDD (Game Design Document)?

A GDD is the primary reference document that defines every aspect of a game’s design — core mechanics, game loop, progression, level structure, economy, UI, audio direction, and monetisation — serving as the single source of truth for all disciplines during production. A GDD is to a game what a technical specification and PRD combined are to a software project.

A complete mobile-game GDD has eight sections: game overview (concept, genre, platform, demographic, positioning), core game loop (the repeating cycle — for match-3: match tiles → earn stars → unlock levels → receive rewards → repeat), player progression (XP, levels, unlocks, difficulty curve), game economy (currency sources and sinks, IAP price points, daily rewards), level-design framework (structure and pacing across the first 50 levels), art direction, audio direction, and monetisation (ad placement, IAP, anti-pay-to-win balance). Starting production without a GDD means game feel and scope are defined in real time during engineering — increasing rework and budget overruns significantly.

What is a game loop and how does it drive player retention?

A game loop is the fundamental repeating cycle of actions a player performs — the moment-to-moment experience that defines whether a player continues or stops. In a casual game the core loop runs at three speeds: the micro-loop (30 seconds — a single match or run), the macro-loop (a 10–30 minute session — progression, unlocks, resources), and the meta-loop (days and weeks — daily rewards, league seasons, social competition).

Retention is measured at three intervals: D1 (return on day 2), D7 (day 8), and D30 (day 31). Casual benchmarks: D1 ≥ 40%, D7 ≥ 20%, D30 ≥ 10%; mid-core: D1 ≥ 35%, D7 ≥ 15%, D30 ≥ 7%. Games below these have a unit-economics problem — acquisition cost exceeds LTV, making paid growth impossible. Improving D7 from 15% to 20% typically increases LTV by 30–40%, making previously unprofitable channels viable. Retention improvement comes from core-loop tuning, progression pacing, and social hooks — decisions that belong in the GDD, not the post-launch analytics review.

What is the difference between Unity and Unreal Engine?

Unity is optimised for mobile development, 2D games, and cross-platform reach; Unreal Engine 5 is optimised for high-fidelity 3D visuals, PC and console games, and photorealistic rendering. Both engines are used by 32% of developers each — the choice depends on the project, not preference.

Four differences drive the decision. Visual ceiling: Unreal 5’s Lumen and Nanite produce film-quality visuals impossible in Unity without extensive custom shaders. Mobile performance: Unity’s URP is purpose-built for mobile frame-time budgets, texture compression, and thermal management. Development speed: Unity’s C# and Asset Store cut time on common systems; Unreal’s Blueprints let non-engineers implement logic. Licensing: Unity starts at $0 (Personal); Unreal applies a 5% royalty only above $1M gross revenue — below that it is free, so for games expected between $100k and $1M, Unreal carries no licensing-cost disadvantage versus Unity Pro.

How much does it cost to develop a mobile game?

A basic 2D casual mobile game costs $20,000–$50,000; a mid-core game with multiplayer and backend costs $80,000–$200,000; an open-world RPG or real-time strategy game with LiveOps costs $300,000–$700,000+. These reflect 2026 rates for professional teams.

Five factors dominate cost. Art complexity is often the largest line item — 3D character art with high-poly sculpts, rigging, and facial animation costs more than the engineering for many indie games; 2D is significantly cheaper. Multiplayer backend adds 20–40% — networking, matchmaking, and CCU-scalable infrastructure are hard problems. Monetisation complexity: a 5-item IAP shop is a 2-day integration; a full battle-pass economy takes 3–4 weeks. LiveOps runs 15–25% of build cost in year one for active games. Platform count: iOS + Android from Unity adds ~10–15% to QA and submission; PC or console adds 20–40% per platform. We scope in phases — prototype first, then full production — so clients validate the concept before committing full budget.

FAQ

Game Development Questions

The things teams ask us most before every game project — answered directly.

Use Unity for mobile games, 2D games, and cross-platform projects; use Unreal Engine 5 for PC or console games requiring high-fidelity 3D visuals. Unity is the dominant mobile game engine — optimised for iOS and Android performance budgets, device fragmentation, and monetisation SDK integrations. Unreal 5’s Lumen global illumination and Nanite geometry produce visual quality impossible to match in Unity without extensive custom shaders. For 2D indie games with no licensing-cost requirement, Godot 4 is a strong alternative. The decision should be made during the GDD phase, before any production begins, because switching engines mid-production costs 2–3× the time and budget of the switch itself.

A hyper-casual mobile game takes 6–12 weeks; a casual mid-core game takes 4–8 months; a multiplayer RPG or strategy game takes 12–24 months. The timeline variables are: art complexity (3D character art is the most time-intensive), multiplayer backend (adds 2–4 months), economy and LiveOps systems (1–3 months), and device QA and store submission (3–4 weeks). We recommend a 4–8 week prototype phase before committing to the full production timeline — prototyping validates the core loop before major art and engineering investment begins.

D1 retention is the percentage of players who return to the game on day 2; D7 is the percentage who return on day 8; D30 is the percentage who return on day 31. For casual mobile games, industry benchmarks are D1 ≥ 40%, D7 ≥ 20%, D30 ≥ 10%. Games below these benchmarks face negative unit economics — the cost to acquire a player exceeds the revenue generated over the player’s lifetime, making profitable user acquisition impossible. Improving D7 from 15% to 20% typically increases LTV by 30–40%. We design retention loops — daily reward systems, progression gates, social mechanics — as explicit requirements in the GDD before production, not as post-launch fixes.

LiveOps (Live Operations) is the ongoing operational management of a live game after launch — including scheduled content updates, limited-time events, economy balance adjustments, push-notification campaigns, and A/B tests on game variables. Games that run active LiveOps retain players 3–5× longer than games without post-launch content. LiveOps requires backend infrastructure built for remote configuration — the ability to adjust reward schedules, event triggers, and store prices without a full app update. We architect this infrastructure during production, not post-launch. Examples: seasonal events that reset competitive leaderboards every 2–4 weeks, limited-time characters creating urgency, and daily challenge systems that give returning players a reason to open the game.

Four main monetisation models exist in mobile games: premium (paid upfront), freemium with IAP (free-to-play with in-app purchases), ad-supported (free with rewarded and interstitial ads), and subscription. Premium ($0.99–$9.99 upfront) works for PC games on Steam and a niche of curated mobile games. Freemium IAP works for mid-core and RPG games where progression-enhancing purchases have clear value. Ad-supported works for hyper-casual and casual games with short sessions where rewarded video does not interrupt the experience. Subscriptions work for games with significant ongoing content output. The monetisation model determines what the core loop rewards — a model mismatch is one of the most common causes of poor ARPU. We define the model in the GDD, not post-launch.

Netcode is the system that synchronises the game state between multiple clients and a server in real-time, managing the latency and packet loss that causes lag in multiplayer games. Poor netcode manifests as rubber-banding (players snapping back to a corrected position), ghost hits (attacks that visually connect but do not register), and desync (players seeing different game states). Modern netcode uses client-side prediction — the client predicts the game state locally so inputs feel immediate, then reconciles with the authoritative server state when the response arrives. We use Photon Fusion for Unity multiplayer projects, which implements server-authoritative networking with client-side prediction. Netcode architecture is decided in pre-production, because the choice between peer-to-peer, relay-based, and dedicated-server systems determines cost, cheat vulnerability, and scalability ceiling.

A soft launch is releasing the game in 1–3 smaller markets (typically Canada, Australia, or the Philippines) before the global release to collect real player retention and monetisation data at lower risk and cost. Soft-launch data reveals D1/D7 retention, where players drop off in the progression, which IAP price points convert, and which tutorial steps cause new-player abandonment. This data drives economy rebalancing, progression pacing adjustments, and store-asset optimisation before global marketing spend begins. A global launch without soft-launch data means spending user-acquisition budget on a product with unknown retention — a high-risk approach in a market where the average mobile game loses 77% of its daily active users within 3 days of install. We include soft launch as a standard phase in every full-cycle mobile game engagement.
