The most interesting feature of the game is that it lets you adjust the playing style of your opponents (see Section 05 of the guide). Also it has an optional display to show which tiles have already been played (see top right of pic from the manual) - I see it more as a convenience rather than a cheat!

Of course this means that I must\'ve got my Nintendo DSi XL - the new version of the DS with screens 93% larger than the DS Lite. The big vibrant screens look great and make for more accurate input on the touchscreen. It has the friendly user interface you expect from Nintendo and overall it\'s a nice piece of kit. The shiny lid does pick up fingerprints though!
