How to play
Each row and each column holds the same number of every symbol. On a Classic 6×6 board that is three of each.
A symbol may appear twice in a row, across or down. A third one in a row is a mistake.
A mark between two cells shows whether they must hold the same symbol or different ones. Follow every mark to finish the grid.
A soft sound as you place each symbol, a chime when a line is complete, and a slow background loop you can turn off. Colour drifts behind the board. Nothing hurries you.
Four board types, all available and playable offline. The 11,222 Classic boards are every 6×6 grid the rules allow. The other three board types are chosen from millions of possible boards.
