Each of the 60 multi-level challenge cards will show you a combination of cubes that needs to be recreated. That*s the easy bit. The hard bit is working out how to position the faces of the cubes correctly. Rows and columns of cubes must show either every face with the same expression, with each being a different colour, or every face having a different expression, but all the same colour. The rules have to apply from the front, back, sides and from above. You*ll probably go through the emotions that appear on the faces of the dice as you grapple with each devilish puzzle, but you*ll end up with a smile when you solve it!
