ToZer0

The board only deals 7s, 8s, and 9s—mostly 9s, very rarely a 7. A tile only moves down by absorbing its neighbors of the same value: touch one, the group disappears, and the tile loses a place.

Your objective: Move a single tile down to 0. Just one is enough—and it's expensive, because each level requires twice as much material as the previous one. Spotting the rare 7 and building around it is the essence of the game.

• A TIMER, NOT A MOVE COUNTER: it starts with your first move and stops at zero. Your score is your time.

• FOUR BOARDS, from a 5x5 grid to an 8x8 grid, lasting from a few minutes to a good fifteen minutes. None are locked: you choose the game length.

• TWO WAYS TO SCORE: by timer or by number of moves. Each game
records both, and each has its own leaderboard—the fastest run is
almost never the most economical.

• LOCAL LEADERBOARDS: your ten best games per board and per mode,
on your device, without an account or login.

• SHARE: a ready-to-post results card, at the touch of a button.

• DAILY CHALLENGE: the same board for everyone, a streak to maintain.

• FOUR-STEP TUTORIAL: each rule is played instead of read, and skipped with a single button.

• BOMBS to unlock a situation, and automatic reshuffling when the board has nothing left: no game lost by bad luck.
