1. Scramble the puzzle blocks by clicking 'Start the Puzzle'. This will also start the timer so you should work quickly after you start.
2. Left-click a block and drag it to a new location. When you let the mouse button go, the blocks will swop - see the picture.
3. If you forget where the blocks should go, click the 'Cheat' button for a quick reminder.
The aim is to put the blocks in the right places. When the last block is dropped into place, the timer stops and you have finished.
If you uncover a prize, you will be notified upon completion. We will contact you to make arrangements for delivery. Good luck! N.B. Only players who have signed up stand a chance of winning prizes.
Click 'Cheat' to check where the edge blocks should go. Once you have a few edge blocks in place, then the rest is easy.
