Right now, the difficulty level is just about perfect for me. I can – and do – fail levels, but I win them more often. I like that sense of danger without getting stuck.

Hopefully the game won’t get too hard.

I’m doing better on the bonus levels now, so I’m starting levels with power-ups fairly often, which helps.

I really don’t think I need to talk about the mechanics of the game. If, however, that screenshot doesn’t tell you everything you need to know, you have to fire balls into the chain that snakes around the screen and when you match three or more of the same colour they disappear.

It’s a good game concept – this version uses the Luxor method of moving across the bottom of the screen, rather than rotating in the centre – and the controls work perfectly in this iPhone version.

It’s also very well presented and even includes an odd feature where your house gets upgraded every few levels.

Not sure what that’s about, but it’s always nice to have some little extras like that in a game.

The game runs perfectly, the controls never fail you, there’s an amusing voiceover and I honestly can’t think of a single complaint. Even the difficulty curve, often a problem in games of this type, has been good so far, starting off easy and gradually ramping up the challenge.

There’s a Lite version that gives you more than enough levels to make a decision and the full version only costs 59p, which seems like a bit of a bargain given the polish and huge number of levels in the game.
