How to play
Fill the grid so every row and every column contains each number exactly once (1 to 4 on a 4×4 grid, 1 to 5 on a 5×5, and so on).
- The signs between squares must be true: < and > across, ∧ (top is smaller) and ∨ (top is bigger) up and down.
- Tap a square, then a number. Notes lets you pencil in small numbers.
- Each puzzle has exactly one answer.
4×4 on Monday and Tuesday, 5×5 midweek and Sunday, 6×6 on Friday and Saturday.
A new puzzle appears every day at midnight. Solve it daily to build your streak.
