Futoshiki is a Japanese logic puzzle. Fill the grid so each row and column contains 1–n exactly once, while every < and > sign between neighbouring cells is respected.

How to play

  1. Tap a cell and enter a digit from 1 to n.
  2. No digit may repeat within a row or column.
  3. Every inequality sign must be satisfied — use them to deduce forced digits.
