Common questions
How do I merge cats?
Buy cats, then drag one onto an identical cat. On the first Rookie merge, choose a permanent role. After that, only identical cats of the same role and rank can merge.
Can I change a cat’s role later?
The role choice is permanent for that cat. Further merges upgrade its weapon and appearance within the same role. Build another branch from Rookie cats when you need a different counter.
How do signature moves work?
Deployed cats charge through useful combat, and merging gives a small bonus. When a cat’s bar is full, tap that cat to activate its signature. Waiting cats keep their charge but do not build more.
Is the Android version available?
The Android release is being prepared. A real Google Play link will appear here when the game is available.
Where is my progress saved?
The current game saves on your device or in this browser. There is no cloud account or cross-device sync yet. Clearing site data or uninstalling can erase local progress. Browser progress does not transfer automatically to Android.
Are diamond helpers permanent?
Each purchase gives one helper deployment. Helpers work for 20 seconds while deployed at the barricade. Moving them into waiting storage pauses their countdown. They do not merge or level up.
