Notes

• Objective / Rules
- Complete the grid such that every row and column contains the numbers 1 to the size of the grid.
- The arrows on the grid are less-than and greater-than signs.
e.g. 1 < 4, 3 < 5, 2 > 1.

• Help
Read the help/walkthrough page on Futoshiki for a more detailed explanation.

• Keyboard Usage [only when your cursor is in the grid]
Note: not all options work on all browsers.
A = auto-pencil marks (or click the check box).
CTRL + arrows = move around the grid.
SHIFT + number = highlight all squares with that number as a pencil mark [SHIFT+0 to clear].

• Mouse Usage
Clicking an less-than or greater-than sign will change its colour, very useful when you know the sign has been satisfied.

• Checking
The system automatically checks that the less-than and greater-than signs are being followed for single numbers (but doesn't check whether the numbers are correct).

If you click 'Check' the system will check for incorrect squares. If 'Show mistakes when checking' is checked they will be marked in red. There are two types of error checked for:
1. A single number that isn't the same as the solution.
2. Multiple numbers that don't contain the solution number.

• Uniqueness
Each puzzle has exactly one solution, which can be found using logic alone and no guesses are ever required. If you think you've found another solution, then please double check the rules.

• JavaScript
This game requires JavaScript to be enabled.
