The game's interface is pretty simple. First and foremost, you see a big cube ready and waiting to move as you wish, and four small buttons in the upper left part of the screen. The first one will start a new game, the second will move the entire cube around randomly, and the next one will undo the last move made, while the last one offers more difficult challenges. Choose from cubes of up to seven by seven and put your brain to the test.
To move any row in Cubex, you just have to use the mouse to click on it and rotate it to the position you want. To complete the puzzle, you can move the cube around to see all the sides. To do so, just click outside the cube and spin it around until you find the side you want to look at. With Cubex, you can have hours of fun solving Rubik's cubes that are as complex as you want.
