Behold, the Phthiraptera in its natural habitat, also known as the common louse or head lice. The lice live on the monkeys, and the monkeys eat the lice. Although it's quite a nasty symbiosis, it's also a perfect example of something we refer to as the circle of life — beautiful!

In Itchy Monkey, several families of lice try to become the more dominant type. Each turn, you spawn new lice and jump over to nearby monkeys. Alternatively you can tickle the monkey, which makes it move and bump into other monkeys. That way more of your little friends can jump over! But beware of your rival families because nobody likes nit picking. The family lice that can build a colony on three gorillas, four of the same animal, or five different species of monkeys wins!

Itchy Monkey is an easy to learn, but very strategic and tactical game, with various starting positions, optional abilities, and a fair amount of monkey business...

In Itchy Monkey: Licence to Kill, players receive three new lice who can infiltrate monkeys of an opponent. If a spy louse jumps (or bumps) to a monkey containing lice of an opponent, all of the lice will stay on that monkey. From now on that "spy louse" counts towards the number of worker lice on that monkey. A monkey may contain only one spy louse at a time.

This expansion also gives you a new game mode in which you control a species of monkeys. (Yes, you won't be playing as lice.) The goal of this game mode is to be the first player to get rid of all of the lice colonizing your monkeys.
