One of the worst effect of global warming is that all sorts of woolly mammoths are breaking out of the polar ice caps in giant ice cubes and racing each other through suburban streets, causing three old ladies to be injured and one tramp to quizzically look at his bottle of gin.

Take away the bits about breaking out of ice caps, injuring old ladies and causing homeless people to believe that they're hallucinating and that's Crazy Mammoths for you – a game where four mammoths in ice cubes race each other down a bunch of hills. The controls for Crazy Mammoths couldn't be easier – spacebar to jump and that's it – but the timing of your jump is everything. Use your crazy mammoths to leap over other crazy mammoths or to block other crazy mammoths from jumping you, but be warned – playing Crazy Mammoths will cause you to tilt your head at a very funny angle.
