press the letters between your fingers to move the knife to that space. Make sure not to press the wrong one or you could seriously hurt yourself! See how fast you move the knife without missing your fingers. Hard mode: click the blindfold button to blindfold yourself. You will have to have memorised the pattern! However, sucessful laps while blindfolded will yield double points.
Don't try this at home! (If you do, do it with a pencil, not a knife.)
