Cubor lets players gently roll colorful blocks to respectively colored designated areas, which will be a familiar trope to veteran puzzlers. But Cubor adds a couple of twists to the formula. Cubes move by rotating in the direction of travel, and as a cube is only truly home when the colored side is face-down, you must assess not only the means of delivery, but also the approach. Not every orientation will do, and part of the solving is in adjusting the cube's orientation so that it can arrive home properly.

You remember Labyrinth, the board game where you turn knobs to roll a little steel ball to the exit, without hitting any holes along the way? Tilt is an example of the wooden labyrinth in 3D digital form, and an excellent one it is, too. Of course, one of the advantages of a digital version is the fact that the maze configuration does not have to stay static, and it certainly doesn't here. There are 66 different levels, many of them devilishly hard.
