Minim for iPhone

Minim is an original, clever puzzler for the iPhone. The $2 game from Fishing Cactus excels because of its simplicity and its elegant ties to the iPhone’s unique interface.

Each level presents a pseudo-molecule—a chain of interconnected numerical atoms. You can tap on two connected, identical numbers in the molecule to combine them; the combined result is incremented by one. That is, if you combine a 2 with another 2, you’re left with a 3 in their place. Your goal is to work each molecule down into a single atom through strategic combining.

The game starts out easy enough, adding complexity as you progress. Each new complication—like “-1,” which decreases the number it’s combined with, or blue connectors, which let you swap the positions of two atoms—is introduced with tutorials that explain just how they work.

Whether tapping on atoms, swiping along the background to rotate perspective, or dragging atoms further apart for a better view, the app’s interactions feel entirely intuitive. While you can undo any number of moves, I do wish Minim included a “start over” button each level, but that’s a minor quibble. On the whole, it’s a low-key and pleasant puzzle game.

The free lite version features five of the full game’s 50 levels—enough to whet your appetite, but not to sate it. Minim is compatible with all iPhone and iPod Touch devices running OS 3.0 or later.
