Nurikabe Player

The Nurikabe Player is for doing puzzles.

Tap on an empty cell to paint it black.

Tap on a black cell and it becomes a "dot," to remind you not to paint the cell black.

Tap on a "dot" and it disappears, leaving an empty cell.

Use the "Reverse Handling" function with "two finger" taps: Put one finger where there are no buttons or icons on the screen and tap the cell you wish to change with another finger. Now a "dot" becomes a black cell, and with one more tap the cell becomes empty.

Disable the "Reverse Handling" function via the "Preferences" screen.

Paint cells continuously by dragging. Click on a black cell and drag, and you can put "dots" continuously. Click on a "dot" and drag to delete black cells and "dots."

Tap on a "dot/black cell" and drag to delete "dots" and "black cells."
