About Can Duel

Can Duel is a free online reaction-time game that boils down to one quick-draw moment. You wait for the SMASH signal and then click as fast as humanly possible, trying to beat the CPU to the button. Click too early and you false-start, forfeiting the round automatically. The CPU starts at a gentle 420ms reaction and tightens to a blistering 170ms by the final rounds, so survival demands actual reflex training. Best of five takes the duel.
