Mobile Game Development — FAQs
Common questions UK and global gaming entrepreneurs ask before starting a mobile game project.
Mobile game development in the UK costs £12,000–£45,000 for a simple casual or hyper-casual game, £45,000–£150,000 for mid-sized arcade or puzzle games with monetisation, £150,000–£450,000 for advanced multiplayer or RPG games, and £450,000–£2,000,000+ for AAA-quality mobile games with complex graphics, real-time multiplayer, AI integration, or AR/VR features. Most UK indie studios spend £45,000–£120,000 on their first commercial game. Ongoing LiveOps cost 20-30% of build cost annually.
We use industry-leading engines based on project needs: Unity 6 for cross-platform 2D and 3D games (most popular for mobile), Unreal Engine 5 for premium 3D and AAA-quality mobile games, Cocos2d-x for lightweight 2D games, Godot 4 for indie open-source games, and native engines (SpriteKit, SceneKit for iOS, native Android with OpenGL/Vulkan). We help you choose the right engine for your gameplay, performance, and budget.
We develop the full range of mobile game genres: casual and hyper-casual games, action and adventure, puzzle and strategy, RPGs, simulation and sports, racing games, casino and slot games (FCA-compliant), multiplayer online games (real-time, MMO scale), educational and serious games, Roblox games, and AR/VR mobile games using ARKit and ARCore.
Mobile game development time varies by complexity. Hyper-casual games take 6-12 weeks. Casual games take 3-6 months. Mid-tier arcade or puzzle games take 6-10 months. Advanced multiplayer or RPG games take 10-18 months. AAA-quality mobile games take 18-30 months. You see playable builds at the end of every two-week agile sprint.
