Considering it’s a game that’s all about colour, Chromixa doesn’t immediately leap off the App Store. Its flat-shaded, 2D, primary coloured polygons don’t exactly set the iPhone’s screen on fire, but it’s one of those ingenious sleeper puzzle games that will become a permanent fixture on your iPhone once you start playing.

The game is so simple it’s hard to convey its gameplay with much excitement, but rest assured it’s tantamount to digital heroin. Building on the basic tangram premise, you’re given a white silhouette shape on the screen, and the surrounding pieces must be fitted together so they match the outline and fill the shape.

Nothing you haven’t seen before. The difference with Chromixa is that filling the central shape is pretty easy, but you’re also required to put your chromatic eye to the test by combining the different coloured pieces so the shape is also filled with a specific colour (usually white). Laying a red shape over a blue shape creates magenta in the overlap, for instance, and adding a further green shape to the mix will create white. Again, it sounds simple and perhaps doesn’t immediately grab your attention, but anyone who’s lost hours of their life to games like Tetris and Bejeweled will seriously struggle to put this one down.

Alongside the massive number of diverse levels is a small selection of mini-games also based around the colour mixing theme. These small additions could easily support their own budget-priced iPhone apps, and offer the ideal break when you’re struggling to bend your mind around some of Chromixa’s harder puzzles.

Overall, Chromixa is undoubtedly the best iPhone game you’re not currently playing.
