Bonsai Blast It's a hugely entertaining Puzzle Bobble-style reaction-tester. The aim is to fire brightly colored balls from a brightly colored cannon. When you get three brightly colored balls in a row, they disappear and you get some points. The tension comes as the balls wind their merry way towards a little yin-yang symbol. For some reason, the yin yang wants to eat your brightly colored balls--hey, it makes as much sense a blue hedgehog running around picking up rings. If it succeeds in swallowing your spherical friends, you lose. Robot Defense You don't get this tower defense game for free, but the demo is smashing anyway. Basically, the deal is that robots want to crush your human flesh and use your blood as some sort of newfangled robo-lubricant for their robotic joints. Your job is to protect your arse and the arses of those flesh-and-bone sacks closest to you. Battleship If you can play this game without hearing the "you sank my battleship" line from The Simpsons, we'll be very impressed indeed. There isn't much anyone can say that will persuade us that Battleship isn't one of the greatest games ever devised. And now, you can play it on your Android phone!
