Bustabrain throws a collection of puzzles and minigames at you, with the objective being to finish them all off in as few clicks as possible.

You've got rebuses, simple clicking games, match removal, memory games, the works. It's nothing amazing, but if you've got a bit of time to kill, it does a good job of filling the void. Halfway through the game, I managed to accidently click on the advert just beneath it and lose all my progress, so make sure you don't do the same!

Give it a play at Ninjadoodle.
