If someone had told me I'd be spending a peaceful night this week in a stark white room playing with bright blocks, I'd have run before they could wrap the straightjacket around my shoulders and throw me into the back of a windowless van. Instead, I spent a few hours positioning primary-colored cubes around a vast test chamber from the comfort of my own home -- with full mobility of all my extremities -- and I enjoyed my time immensely. Toxic Games' Q.U.B.E. (Quick Understanding of Block Extrusion) joins other puzzlers as the crossword of the plugged-in generation, stimulating spatial, physics and reasoning skills in a direct way that shooters can't touch (or shoot).
