SAME PRESS, DIFFERENT RULES

See how one move
changes the board.

Only a floating tile can be pressed. It sinks, and tiles that share an edge with it flip state. Tiles that touch only at a corner do not react.

01RISE & SINK · ALL DOWN

Keep every tile. Sink them all.

The number of tiles stays the same in this mode. Sink every tile to clear the puzzle.

This example uses three tiles in a row. Pressing tile 1 flips tile 2; pressing tile 3 flips tile 2 again.

02TILES DISAPPEAR

Sunken tiles can disappear.

After neighbors flip, any sunken tile with no floating neighbor along an edge disappears. When no floating tile remains, all remaining sunken tiles disappear and the puzzle clears.

After the final press, all three tiles are sunken. With no floating tiles left, they all disappear.

YOUR FIRST PUZZLE

  2. Choose a puzzleStart the next unsolved puzzle or choose from the list, organized in groups of ten.
  3. Press a floating tileCheck its number and state symbol, then see which edge-sharing neighbors change.
  4. Choose what comes nextAfter solving a puzzle, continue to another puzzle or return to the list. An unfinished board is saved on this device.

TOOLS FOR THINKING IT THROUGH

Look again, go back,
and try a new move.

Here is what each helper does during a puzzle.

✦

Hints

The app searches from the current board and, if it finds a route, suggests the next tile to press. If the search reaches its limit, that does not prove the puzzle is unsolvable.

↶

Undo and redo

Step back through your moves, then step forward again. You can try another move from the restored board.

↻

Restart

Restart immediately returns the current board to its initial layout without a confirmation dialog. It does not delete the puzzle's completion record. Deleting that record is a separate action.

▦

Puzzle list and progress

Each rule has 100 puzzles, shown in groups of ten. From the home screen, resume a saved puzzle, start the next unsolved puzzle, or choose one from the list.

▤

Play records

Progress is tracked separately for each rule. Each puzzle's record shows whether you have completed it, the completion date, your latest and best move counts, and how many times you have completed it.

▣

Rules and guided practice

Revisit either rule at any time. Separate practice examples compare the board before and after a move; they never change your puzzle progress or records.

DISPLAY AND ACCESSIBILITY

Tune the view
to suit you.

Settings are saved on your device. State is not conveyed by color alone: symbols also distinguish floating and sunken tiles, as well as tiles that have disappeared.

  • Japanese and English
  • Three text sizes
  • Three tile palettes
  • High contrast
  • Reduce motion
  • Optional haptic feedback

Display choices do not change the puzzle rules.

PROGRESS AND BACKUPS

Saved on your device.
Back up and transfer manually.

Puzzle progress, play records, and display settings are stored on the device. There is no automatic cross-device sync.

You can export a backup and import it on another device. Importing replaces that device's progress and display settings. The app saves a recovery copy of the current data before replacing it.

A backup contains progress and settings. Choose where you store or share it, and do not post it publicly.
