How to play — Futoshiki
Fill 1…N so no number repeats in any row or column — a Latin square, like mini-Sudoku.
Every sign between two cells must hold: the POINTED tip always aims at the SMALLER number (‹ 3 means “less than 3”, ⌃ means the upper cell is smaller).
Tip: a cell at the small end of a chain like a‹b‹c can’t hold big numbers — chains pin values fast. Amber cells are given and locked.
Tap a cell then a number (or type; X/0 clears). Given numbers are locked. The tip of each sign always points at the SMALLER number — a broken sign glows red.
