Finger Slayer - is the most fascinating game on reaction. Check the speed of your reaction, trying to evade from a guillotine edge! Simply touch a guillotine circle with your finger and wait for a countdown. After counting ends, take away your finger as soon as the edge starts falling. The longer you will be able to wait until the edge falls, the more points you will get. But if you take away a finger too early the game will end, so count the time correctly.
