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. Notice the feedback after each input.
The challenge in front of you
Fill a 4×4 Latin square and satisfy every cage arithmetic target. The feedback beside the game helps you follow the round. Take a moment to understand the current position.
How a round unfolds
- Select a square and enter 1–4.
- Combine all cage digits using its shown operation.
- Subtraction uses the absolute difference.
- Check puzzle verifies the entire grid.
Keyboard and screen controls
Click or tap squares or graph edges. Number boards include a digit pad. Undo reverses the previous change; Check puzzle validates the solution. Keep the playing area visible while using these controls. Return to the rules if the result is unexpected.
One way to understand the rules
A two-cell 6× cage contains 2 and 3 in a 1–4 puzzle. Focus on why the action is allowed, not only its outcome. Keep the game’s format in mind.
One detail worth checking
A correct cage total does not permit duplicate digits in a row. Read the feedback to see why an action did not have the expected result. Take enough time to read a new position. If a game has a timer, learn its controls first rather than searching for them during the round.
