ABOUT THE GAME
Futoshiki game overview
Futoshiki unfolds on square grids where every row and column must contain one through five exactly once. You enter missing numbers while satisfying both uniqueness rules and the inequality signs between cells. This five-by-five inequality number logic rewards cross-checking a candidate against its row, column, and every greater-than or less-than clue touching the cell. Solved boards lead to additional Futoshiki layouts that require tighter deduction across intersecting clues. Within this five-by-five inequality number logic, compare cause and result. Progress stops while any duplicate number or violated inequality remains on the board.
WHAT TO EXPECT
Before you start
Expect five-by-five inequality number logic in Futoshiki. Fill the complete grid with valid numbers from one through five. The challenge changes because solved boards lead to additional Futoshiki layouts that require tighter deduction across intersecting clues.
GETTING STARTED
How to play Futoshiki
Start Futoshiki by checking the goal. Next, enter missing numbers while satisfying both uniqueness rules and the inequality signs between cells. Before acting, favor cross-checking a candidate against its row, column, and every greater-than or less-than clue touching the cell.
Continue from a safe position. Solved boards lead to additional Futoshiki layouts that require tighter deduction across intersecting clues. After failure, reconsider timing for five-by-five inequality number logic.
CONTROLS
Controls and device setup
Click or tap a cell, then choose its number from the on-screen controls; tap the selected cell again when you need to toggle note marks.

Tips for Futoshiki
- Fill the complete grid with valid numbers from one through five. Inspect the nearest constraint before the next input.
- Cross-checking a candidate against its row, column, and every greater-than or less-than clue touching the cell. Keep the five-by-five inequality number logic priority visible.
- Progress stops while any duplicate number or violated inequality remains on the board. Plan the next attempt around this limit.
