Available on Uminin's Flash Game Zone, home of several other previously reviewed works, the curiously named Brain Force is not very intellectual. No, Brain Force is purely an elegant exercise in agility, a beautiful example of how little is needed to make a successful twitch game.
The playing field consists of a 6x6 grid of tiles which, randomly and at increasing speeds, flip over. You must reset each flipped tile by clicking on it before the attached timer runs down and explodes. Flipping a tile earns you 100 points. You can earn a Speed Bonus (+500) if you flip it immediately after the timer is exposed, before any dots are visible. The dangerously tempting Bravery Bonus (+2000) can be won by flipping the tile after the 10th dot on the timer appears. The game ends when a single tile is destroyed. Afterwards, your score is ranked and, cryptically, an IQ is assigned.
The rules of Brain Force are simple and the end is inevitable - you will fail. Similar to classics like Space Invaders or Qix, Brain Force is successful in spite - or because - of it's simplicity. The only goal is to do a bit better than the time before and, if you've got an itchy mouse finger, sometimes that's enough. Click.
