How to play

Drag a piece from the tray onto the board. Fill a full row or column and it clears. The game ends when none of the three pieces in the tray will fit anywhere.

The free hour and the unlock

Knubble is free for the first hour of play. After that, a one-time purchase unlocks the full game forever — no subscription, no ads, and nothing else to buy. Only time spent actually playing counts toward the hour.

I already paid but the game is locked

Tap Restore purchase on the unlock screen. Make sure you are signed in with the same Apple Account or Google account you bought it with. If it still will not restore, email us and we will sort it out.
