Download: Planet Fish

The iPad is ideal for micromanagement games. Planet Fish is an entertaining game in this genre, very similar to Snoopy's Street Fair that we reviewed last year. The aim is to catch fish in a mini game and then look after them in one or more aquariums. Once the fish have grown they can be sold for in game money that can be used to improve the aquarium and unlock new areas.

You start with an empty aquarium and so need to start by selecting a map to fish on. The selection of maps increases as you progress through the levels. Maps can be unlocked early by spending one of the ingame currency.

Select your submarine and you are ready to start the fishing mini game. The idea is to catch fish in bubbles. Tilt the iPad from side to side to move the submarine and tap the screen to fire a bubble.

The bubble can be drawn towards the submarine by tapping again. This can be used to help reach otherwise inaccessible areas or to avoid obstacles. There are spikes and jellyfish that pop bubbles as well as currents to knock the bubbe off course.

The mini game ends when you either run out of bubbles or free space in the aquarium.

Once the fish are in the aquarium they need feeding and you gain experience every time they feed. Fish can be sold to earn coins. They earn the most coins once they are fully grown. Generally speaking the more coins a fish is worth, the longer they take to mature. If you choose to hang on to fish they earn money every so often as long as they are well fed.

Coins can be spent on various decorations for the aquariums, most of which give a bonus to the amount of money earnt from fish.

Coins are not the only form of ingame currency. There are also rubies. These are earnt slowly on leveling up or can be bought with real money through an ingame purchase. Rubies and Coins can be bought in packs going all the way from 70p to £70, so it's probably not a good idea to leave children playing if they know the password.

Rubies unlock some of the more interesting submarines and decorations but the game is still playable without them.
