Invert
Enticingly simple, surprisingly hard $2.99 Developer Noodlecake Studios, noodlecake.com Platform Universal Requirements iOS 7.0 or later You may have played a game like Invert before, in which you are presented with a grid, and several buttons around the perimeter that flip some of the tiles on the grid to change their color. Your objective is to turn all the tiles the same color, and though Invert starts off fairly slowly and easily, it soon becomes maddeningly difficult once you get to the later levels.
The first few levels are mostly square, which means even the most spatially challenged players can probably figure out what each button does. Later, though, the grids change shape, from triangles and hexagons to confusing double-helix shapes and twisty diamonds.
Invert is a relatively short game, especially if you breeze past the first 10 shapes, each with eight different configurations to solve – but once you’re done with the regular puzzle mode you can switch to “Challenge” to solve as many puzzles as you can against the clock, and eventually “Expert,” which is like Challenge but obviously much harder.
Invert is the kind of game that is immensely satisfying in the same way that it’s satisfying to arrive at an elevator just as the doors open, or to find spoons that stack perfectly. Seeing the colored tiles flip over in a very stylishly animated way feels like cosmic alignment, with you the architect of it all.
The bottom line. A brain-tickling puzzle game that will suit lovers of Rubik’s Cube and other precise puzzlers. Kate Gray great
