At the beginning of each game, you will be presented a set of matches and be asked to add or move or remove a number of matches to form a number of squares. The rule is that every square counts. So a match can be part of a small square and part of a big square simultaneously. There must not be idle matches also, hence every match must be part of a square.

Each puzzle is generated by the computer, so sometimes it is easy to give you some achievement, and sometimes it is challenging to give you some exercise to the brain.

You can play the unregistered version for an unlimited time, but each game is restricted to 1 minutes and you cannot undo your moves.
