A Japanese number puzzle solved by logic alone. Six grid sizes from 4×4 to 9×9, with a fresh puzzle every time.





Futoshiki is a Japanese number puzzle and logic puzzle in one. Fill the grid so that each row and each column contains every number exactly once, and every inequality sign (< or >) between neighboring cells holds. The pointed side of a sign always faces the smaller number.
Every puzzle is generated fresh for you and has exactly one solution. Every puzzle can be solved by logic alone, with no arithmetic needed.
■ Six grid sizes
Start with small 4×4 grids and move up through 5×5, 6×6, 7×7 and 8×8 to 9×9. Solve a size three times to open the next one.
■ Simple controls, with notes
Tap a cell, then tap a number. Turn on Notes to keep several candidates in a cell. Numbers that break a row, column or sign are shown in red.
■ Help when you need it
A five-step interactive tutorial teaches rows, columns, signs and notes. Reveal puts the correct number in one cell, Check marks your mistakes, and Auto notes fills in candidates for you.
