This is interesting. Tech meets "old"...Many combinations possible....over 600 they say

Now this is an interesting mix of tech and play. The four magnet cubes have LCD displays to imitate a wide array of puzzle pieces. You twist and shuffle the cubes till you get the puzzle together correctly. And you won't get bored, as there are 600 puzzles to complete. Oh, the puzzles are timed, so you have to work fast.

600 DIFFERENT PUZZLES IN ONE!!!
"Here´s why: Cubed (for short) is composed of four electronic cubes. Each one is surrounded on four sides by magnetic connectors, and each displays 1/4 of the puzzle on its LCD screen. Now, you just have to figure out how the pieces connect together as you connect the cubes via their magnets. There are even two separate games you can play: you can make pictures and icons by forming a square shape, or you can form words in a rectangular shape. All 600 puzzles are shown in the instruction manual, but when you hear the timer beeping down, there isn't enough time to cheat. Get ten puzzles solved in a row and you win."
