3D Logic is a fantastic puzzle game developed by Alex Matveev. The goal of the game is really simple: connect each pair of same-coloured blocks with an unbroken line without crossing over another colour.
Controlling the 3D cube with your mouse, you must click on a coloured block and drag along the empty spaces to create a line that connects the pair. As there is no time limit, don’t worry if you make a mistake in the process of drawing a line. Just use the undo or restart buttons.
With beautifully smooth graphics, an automatic save which allows you to come back later, and clever gameplay, 3D Logic is a well designed and addictive puzzler. Expect to spend a couple of hours (or more) to complete all 30 levels.
