The bloon tower defence reminds me of an iphone game that is tap defence where you place several weapons and obstacle to prevent the baloon from exiting the system.

Meet the Royal Beasts, the fantastically fearsome animals kept in the terrible Tower of London. Our seven microgames feature three ravenous lions, a polar bear fishing in the Thames, a furious baboon, a ghost bear and much more! Come on, a furious baboon!!
