There are perhaps as many Breakout-style games as there are grains of sand on a beach, but what if every brick in the game was itself another tiny version of Breakout? Designer Alan Hazelden's BRICK[bricksmash]SMASH starts with a ball, a paddle, and 16 colored blocks. Inside each block is another paddle and 10 tiny bricks. And every time you hit a block, you start a new game inside it. Stick with it for more than a few minutes, and you'll be keeping track of a dozen balls in varying sizes and colors, trying to get those elusive remaining bricks.

BRICK[bricksmash]SMASH may have the same DNA as an executive time-waster like Brick Breaker, but it ends up subverting the whole concept of a low-investment browser game by requiring intense concentration: from what we can tell, you can't even pause it. We assume the limited resolution is the only reason it's not just a fractal made of ever-smaller bricks and paddles.
