Logix3D - Logix3D is original J2ME puzzle game, where you have to put coloured boxes on a spot with the same colour as the box. You've got multiple boxes which are moving all at the same time but they can't get through walls. So if you want for example to separate 2 boxes, you just place one of them behind a wall so it can't move. But it's not at all as easy as it sounds.
Levels are divided into 5 categories according to their difficulty and each category contains 25 levels = over 120 levels in whole game. The last category has new game style, which requires thinking several moves forward.
In menu, you can adjust graphics details to run this java game smoothly even on some older devices, you can also adjust here the altitude and distance of the camera to have better view at whole scene. You can of course save your unfinished level or even create up to 25 levels in special ingame level editor. And if you know someone who plays this too, you can compare your statistics and number of moves with him to see who is the more intelligent.
