Daily Inequality

How to play Inequality

Inequality — also called Futoshiki — is a Latin-square logic puzzle. Each cell holds a number from 1 to N (where N is the grid size), with every number appearing exactly once in each row and column. Between some cells sit < and > signs: the open, wide end always faces the larger of the two numbers, so the pointed end aims at the smaller one.

THE RULES

1. Every row must contain each number 1–N exactly once.
2. Every column must contain each number 1–N exactly once.
3. Every sign between two cells must hold — the open end faces the bigger number.
4. Cells with no sign between them carry no extra restriction.

BEGINNER STRATEGY

• Hunt for forced extremes. The cell at the pointed end of a long chain of signs can't be the biggest number, and the open end can't be the smallest.
• Follow the chains. A run like a < b < c forces three increasing values — on a small grid that often pins them outright.
• Combine signs with Latin-square logic. Once a sign rules a value out of a cell, normal row/column elimination fills the rest like Sudoku.
• Use the givens as anchors. A pre-filled number plus an adjacent sign instantly bounds its neighbour.
