Inequality Grid

Fill a square with each number once per row and column, obeying the greater-than and less-than signs between cells. Daily and practice grids.

How to play

  1. Select a cell, then choose a number on the pad or type it. Every row and every column must contain each number from 1 up to the grid size exactly once.
  2. A sign between two cells tells you which is larger. Across a row the sign points to the larger number, and for stacked cells the caret opens toward the larger number.
  3. Given numbers are locked. Repeats show in red, and a sign turns red when both cells are filled and break it.
  4. The puzzle completes when the grid is full with no repeats and every sign is satisfied.

Tips and strategy

  • A cell that must be smaller than a neighbour cannot be the largest number, and a cell that must be larger cannot be 1.
  • Chains of signs such as a < b < c fix the order of three cells at once.
  • In a 5 by 5 grid, a cell smaller than two neighbours is often a 1 or a 2.
  • Use the given numbers to finish rows and columns that are almost full.

FAQ

Can there be more than one solution?
Yes. Any grid that meets every rule is accepted, because the game checks the rules and not a stored answer.
What do the signs mean?
Between side-by-side cells the sign points at the larger one. Between stacked cells the caret opens toward the larger one.
Is the daily grid shared?
Yes. It comes from the UTC date and resets at 00:00 UTC.
