- Regions (number bubbles connected by lines) generated from clues on the board
- Rules act on regions to mark bombs, clear squares or create new regions
- A checker tells you if your rule is formally correct
- Rules are auto applied forever after, resolving the situations you have solved before
- Only the hard situations remain.
- A hint system can mark the determinable squares and remove all unnecessary regions from the board.
- Regions can be hidden or discarded using rules
- Thousands of levels to play, all solvable without guessing.
