The Marble Cake consists of a bottomless tray made of Japanese elm with seven different pieces made from exotic hardwoods including Japanese beech, magnolia, paduak, teak, wenge, ebony and cherry). Construction and finish is very good indeed and the fit is just nice with the right amount of tolerance between the pieces.
|Three of these tetraminoes....are not like the others....|
As a result, this makes the Marble Cake far far more tricky and difficult than if it had just been a packing puzzle with seven regular tetraminoes. It took me a good hour or so before I got all the pieces flush into the tray!
If its any help, the trick I suppose is not to think of the odd pieces as odd if possible, but to see how they could possibly fit into the tray if they were just regular tetraminoes (which of course is easier said than done, with the benefit of hindsight).
This is really a very nice packing puzzle with a good level of challenge. Its difficult but not frustratingly so. An original design and with only one solution. For packing puzzle fans, the Marble Cake is a must-have for collectors.
