Built for every screen
Our games run in desktop, phone and tablet browsers. We build with Unity 6 and Cocos and tune each game for quick loading.
Ready for your SDK
We integrate your platform's SDK for ads, rewarded videos and progress saving, and follow your technical requirements.
Flexible deals
Exclusive or non-exclusive distribution, or a custom build made for your audience. Tell us what works for you.
