The plot of Oh Sheep is rather tenuous to say the least. The evil Dr Friedrich is trying to take over the world with some brightly colour berries. Intergalactic sheep step in to protect Earth by picking them up first. Don't worry because the game itself makes a lot more sense and is a lot of fun.

The sheep can be directed around the fields by tapping on them and then dragging a path to show them where to go. It's a simple idea and it doesn't take long to be able to direct several sheep around at the same time.

Some challenges require good timing as the sheep have to avoid lasers set up by Dr Friedrich.

It's the berries that create the real challange in the game. As a sheep eats a berry, it changes colour to match the berry. Some switches can only be operated by sheep of the correct colour so some careful planning is required.

You can collect diamonds that can be used to reveal the solution to levels or simply to skup them. Diamonds can also be bought using real money. Solutions and skipping cost ten diamonds each.

Real money can also be spent to unlock all the levels on offer. 69p seems quite reasonable.
