Futoshiki: what to know before playing
Choose a round of Futoshiki and settle into its rules. Place 1–4 once in each row and column while obeying every inequality. Choose a clear next step rather than rushing through the instructions. Make your first input carefully and watch the result. Use the example below to understand a decision.
Twelve 4×4 puzzles with fixed starter values.
Take a closer look while playing
Compare the worked example with your own position. Use the reasoning, not an answer copied from a different board. Refer to the controls when needed.
Your goal
Place 1–4 once in each row and column while obeying every inequality. The feedback beside the game helps you follow the round. Keep the controls in easy reach.
Start here and follow along
- Select an editable square.
- Read inequalities by their row/column coordinates below the board.
- Enter 1–4.
- Check puzzle verifies both Latin-square rules and inequalities.
How to use the controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. A careful first action helps you become familiar with the layout. Look at the feedback after the action.
Put the rules into context
r1c2 < r1c3 means row 1 column 2 is smaller than row 1 column 3. Use the example as a guide rather than a substitute for reading your board. Take a moment to compare.
Check this before moving on
An inequality specifies order, not an exact difference. A different version of the game may use a different rule. When a decision goes wrong, compare it with the common mistake described below. Start again only when you intend to leave the current round.
