App O' The Mornin': Chain Link Pro Review

Chain Link Pro is a game that kind of sneaks up on you. It's a simple concept that would appear to have limited appeal., but it turns out to be a keeper.

The screen displays different shapes around a swirling vortex. You have use your finger to select one shape, link it with any similar shapes, and drag the whole floating chain into the vortex without touching any other shapes.You can't move to fast, or your chains will swing around and hit the edge of the screen, shattering.

This starts out fairly easy, and after a minute or two you may be tempted to drop it altogether. Stick with it: there's actually nice balance of strategy and dexterity here. Powerups help you pump up the score when making chains, or altar the way the shapes react.

The levels get progressively more challenging, but not so much that you're hurling your device across the room. Three different modes of play mix things up a bit. In Static mode, the shapes don't move, in Timed mode, you're racing against the clock, and in Arcade mode, you have to avoid moving objects. It's a small game, but one that's a good pick-up-and-play addition to your iPhone.
