Ever since Ernő Rubik crafted his famous cube in 1974, there's been a certain satisfaction in matching color-coded blocks to one another. Nowadays, unless you're a genius you likely gave up on one of those after 10 minutes or looked up a solution. Qvoid similarly tasks players to combine color-coded cubes, only this time you're pushing a cube around a three dimensional plane and it's a lot more forgiving and fun.

Your cube always starts out pure white, but roll over a colored surface, and that side of the cube will change color too. The goal of each level is to pick up every colored surface and deliver it to its counterpart on the floor until the map is monochromatic. It sounds simple, but a harsh set of rules dictate where you can and can't move. For example, you can't roll a colored surface onto shaded ground, and before you know it you're mixing primary colors and navigating past crumbling one-way tiles.

You're not rated on time, so feel free to contemplate until you reach your moment of zen.

It can get fiendishly difficult, but thankfully there's a handy Undo button that can be used ad infinitum with no penalty. A three-tiered reward system rates you on number of moves, so carefully undoing and reassessing each move becomes mandatory. After a while, you gain a feel for certain maneuvers, and strategies that previously eluded you become commonplace. The rules may not change, but your understanding of them will.

Presentation is relatively minimal, but in an inspired choice, your cube has a face indicating how you're doing. When it maintains its smile, you're on the right track, but its eyes close if you've made a misstep that renders the solution impossible. It's the kind of subtle hint that guides you in the right direction without spoiling the solution.

Each stage's title reveals a subtle hint regarding its solution.

Elsewhere, the game controls very well, with the touchscreen inputs seldom misread. Flicking your cube around and rotating the camera feels natural throughout.

Qvoid may require patience, but it's rarely frustrating. The option to skip troublesome puzzles, lax requirements for unlocking new content, and the Undo button are godsends, transforming these brain busters from arduous to accessible. In short, it's a Rubik's cube that doesn't hate you.

The bottom line. A puzzler about pushing a cube around to match colors, Qvoid may seem rudimentary, but its forgiving design and tight levels manage to be difficult without being daunting.
