Less like maths, more like fun!

Sudoku Solitaire is a version of the popular puzzle game using colours instead of numbers. To solve the puzzle each row and column and each 3x3 square must contain one (and only one) of each colour.

Drag the coloured tokens into spare spaces on the board using the clues provided to decide which can go where. You can drag them in any order to any location and can drag them off again if you change your mind. Invalid moves are blocked and the tokens blocking that move are highlighted.

Special Features

This version also includes some special features to make playing Sudoku Solitaire even more of a pleasure.

Bookmark and Restore

If you reach a point you know is right but then want to experiment pressing the Bookmark button will mark your current positions so you can return to it later by pressing the Restore button.

Note Highlighters

It is often useful to add notes to a pot on the board where you have identified the specific options for that pot. Simply drag the highlighters onto the board and then click on any of the four corners to cycle through the colours until you get a colour you want to consider for that pot.

You can position the Note Highlighter directly over the pot in question or between two - whichever is most convenient.

Show Errors

You can check your solution at any point by pressing the "Show Errors" button. This will highlight any tokens that are incorrectly placed. If there are no errors a small bell sounds - well done!

To discourage you from relying on this feature it only becomes available after 20 minutes of game play - so try to puzzle it out yourself!
