Kubik

This puzzle game isn't overly complex and can feel repetitive at times, but since each stage's configurations constantly change, it can become an addictive pastime. Players repeat the same basic activity over and over again -- swiveling a base around so that pieces fit into the right spot as they fall toward the ground. Options aren't unlimited -- pieces can't be flipped, and the way they fit into your structure depends on how well you've stacked previous items. But that's part of what makes the game interesting. Highlighted areas indicate where pieces will fall to help you visually determine what's best. The ability to speed pieces' descent by holding a finger on the screen can also help alleviate any sense of boredom if you're waiting for a piece to fall. Rounds appear to feature increasingly complex pieces, which can help provide consistent challenges.

The app could, however, use a little more background -- and some more instruction. There's hardly any text; it's not initially clear, for example, why you're getting gems, the app's currency. That may be because there isn't much to do with them; a certain amount will grant you access to a different background, which really isn't all that exciting. Adding more incentives to play wouldn't be a bad idea; incorporating logic-based playing tips and/or hints, in case kids find they aren't making as much progress as they'd like, would be an even better one. But for players looking for an engaging puzzle game to pass the time, Kubik could be a fun way to spend a couple of minutes.
