Futoshiki

Numbers without repeats

A Futoshiki puzzle combines a number grid with comparisons between neighbouring tiles. Use every number once in each row and once in each column. The given numbers stay fixed; fill the empty tiles yourself.

Read the pair of beads

The larger bead belongs beside the larger number, and the smaller bead beside the smaller number. A pair compares only its two neighbouring tiles. A horizontal pair does not compare a whole row, and a vertical pair does not compare a whole column.

Enter and revise a number

Select an empty tile and then a number from the tray. On a keyboard, use the arrows, the number keys and Delete to clear an entry. The information button above the field keeps the full rules and controls nearby.

Combine comparisons with missing numbers

Futoshiki puzzles ask you to use both rules at once. Check which numbers are missing from a row or column, then see which can still fit a bead comparison. A number may be legal in its row but too large or too small for its neighbour.
