Every Match-3 project we start with a market audit and your idea. We've built numerous casual games turnkey — from prototype to publication in App Store and Google Play. With 7 years in the field and 15+ projects launched, we know all the pitfalls: from bugs in cascade animations to ad monetization blocks in certain regions. Here's how the engineering kitchen of the genre works and what's important to consider at the start.
Match-3 is a casual genre with deep technical layers: board algorithms, animations, monetization. Without refining each layer, retention drops and the ad budget doesn't break even. Our team guarantees the game runs stably on devices of any level, from iPhone SE to budget Androids with 1 GB RAM. We use profiling tools and stress testing.
The first technical element that determines a game's success is board algorithms. They handle how pieces fall, matches are processed, and deadlock situations are avoided. Let's dive into the details.
Board Algorithms: Details That Matter
Match detection is not just "find 3 identical in a row". You need to handle T-shaped and L-shaped patterns and prioritize them. Implementation: first mark all matches with a bitmask, then determine the shape through chain intersections.
Gravity and cascades: after removing pieces — falling from top to bottom, filling from spawners. We use a coroutine-based sequence: first deletion animation (150ms), then fall (200ms), then check for new matches — until stable state.
Deadlock detection — after each move, check for a valid swap. If none — shuffle. O(n) algorithm for a 9×9 board — 144 swaps in <0.1ms.
Why Cascade Animations Are a Bottleneck
The player must see the physics of pieces falling, otherwise the feeling of a "live" board is lost. We synchronize animations with the Update timer in Unity or using async/await in Swift. This delivers smooth 60 fps without micro-lags. Details available on request.
How We Monetize Match-3 Without Losing Users
Classic: rewarded video for +5 moves. We show the offer when the player has spent the last move and is close to winning (remaining quest objects <20%). This gives 3-4 times higher conversion. The logic requires real-time quest counters — a layer between UI and the game model.
We also implement in-app purchases: extra boosters, unlimited lives for an hour, ad removal. The choice of monetization depends on the audience — Chinese profit from IAP, Western from ads.
Comparison of Approaches: Native vs Cross-Platform
| Criterion | iOS (Swift + SwiftUI) | Android (Kotlin + Compose) | Flutter |
|---|---|---|---|
| Animation performance | 60+ fps | 60+ fps | 60 fps with tuning |
| MVP development time | 2–3 months | 2–3 months | 1.5–2 months |
| Access to native APIs | Full | Full | Via plugins |
| Risks under hood | Low | Low | Medium (plugins become outdated) |
For complex cascade mechanics we recommend native — it gives control over memory and animations. Flutter is suitable for simple prototypes.
Turnkey Match-3 Development Stages
| Stage | Duration | Result |
|---|---|---|
| Analysis and design | 1–2 weeks | GDD, economic model |
| Prototype (MVP) | 6–8 weeks | Working board, 10 levels |
| Full cycle (60 levels) | 3–5 months | Complete game with monetization |
| Publication and support | 2–4 weeks | App Store Review, FRT |
What's Included in Development
- Game level design with deadlock-free generation.
- Board algorithms (match detection, gravity, shuffle).
- Particle animations and transitions (smooth, 60fps).
- Monetization (rewarded video, IAP, subscriptions).
- Analytics (Firebase, Amplitude) — dashboards for retention, ARPU.
- Publication in App Store and Google Play.
- 30 days of technical support after release.
We also include beta testing via TestFlight and Google Play Console.
How Long Does Development Take?
A standard Match-3 project with 60 levels and monetization — 3–5 months. When using a ready-made engine (e.g., our algorithm library) — from 2 months. We evaluate your project in one working day — just contact us.
We guarantee code quality: test coverage, code reviews, compliance with Apple and Google guidelines. 7 years of experience and 15+ projects allow us to avoid typical mistakes.
