Click the board to let Zillions randomize the setup. Twentyfive puzzle pieces will appear, each in a different colour. The puzzle pieces are polysquares.
One of the coloured squares in each piece has a black dot ('handle'), which marks the part that has to be placed on one of the square target positions in the box at right.

For technical reasons all movements have to go via a special center position: Clicking a handle will transport a puzzle piece to the special central position.
Clicking an empty target position (i.e., one marked by a small black square) will transport the puzzle piece from the centre to its target, which may be in the box or at one of the starting positions at the left part of the board.
Again: all movements are either from or to the central position in the middle of the board.

Beginners: You win when you fit all piece into the box at right.
Experts: Fit all pieces into the box, but leave no gaps betweens pieces. (Gaps between a piece and the border of the box are allowed). Note that such a solution is ALWAYS achievable in this game!

The other two variants use 9 and 16 puzzle pieces instead of 25 and are therefor easier.

Please note that there is an alternative piece set available.
