Zeptolab's addictive puzzler Cut the Rope has received 25 new levels, in a fresh update now available on the iOS App Store.

The update is called Steam Box, but it has nothing to do with Valve's mysterious new games console.

The level pack is actually named as such because it adds wispy steam clouds as an extra puzzle element for Om Nom (the hungry green monster) to deal with.

The Pocket Gamer Silver Award winner already has a whopping 325 levels, and they feature whoopee cushions to bounce the candy in different directions, bubbles that trap and float it around the screen, and hindrances like spikes and spiders.

These new steam clouds raise the candy up to help feed Om Nom. The amount of steam can be controlled with pressure valves.

Now go. You have a hungry, hungry monster to feed.
