Crazy Crystals, our 'rock-hard' puzzle game, has made its appearance on FunOrb! Packed with levels, this game gives you endless hours of mind-bending fun.

You can choose from four game modes: One-Player, Two-Player, Three-Player and Arcade. One-player is split into three sections of 20 levels each, starting easy and then ramping up to a dizzying difficulty. The Two- and Three-player modes offer a number of puzzles that you and your friends can solve together on the same machine. Finally, we've got Arcade mode, where your reaction speeds are more of a factor.

Of course, all of this comes with a new raft of Achievements, some of which are diabolically difficult to get. You have been warned!

So, get your grey matter working at top efficiency, flex your fingers and test yourself on Crazy Crystals. See how far through this brain-straining game you can get...
