How to use Puzzle Bubble Mines
- Choose a locked piece from the 5×4 collection board.
- Pop safe bubbles and flag neighboring mines; the first bubble and its neighbors are safe.
- Finish the board to collect that piece, with difficulty increasing every five pieces.
- Sign in to sync progress across devices and download the complete artwork after collecting all 20 pieces.
Compatibility and limitations
- The first release includes one original City Lights collection with 20 pieces.

- Accounts store piece numbers and best times only; there is no real-money play, lottery, or physical reward.
Privacy policy
The active board stays in this browser. Signed-in accounts sync only unlocked piece numbers and completion times, not move history or share images.
