Right then. Do listen up. Here's a word and picture puzzle designed and built for the digital age. From the outside, it looks like a block game. But how dull would that be? After all, blocks are for toddlers.

But not these blocks. For these are blocks with electronic wizardry at their heart. Each of these blocks is in fact a cube measuring 6.5cm square, containing a display screen. Each cube interacts with adjacent cubes to enable the display of words and pictures. Your challenge, not to put too fine a point on it, is to unscramble said words and pictures to win the game.

Sounds easy in theory, of course, but with over 600 different words and pictures pre-stored, and an almost infinite number of display combinations, this is a real head scratcher of a puzzle. Twist them. Spin them. Slide them. Rotate them. Re-work the order again and again. Sometimes the right order just can't be found.

A time limit of 40 seconds is strictly enforced by the cubes themselves. And a ten second alarm sounds before time is well and truly up. All of which makes for an intriguing final phase as the clock ticks down towards your certain defeat.

Endless frustration. Endless possibilities. Endless fun.
