Cerkio GD

You're a ball. The circles are spinning. And somewhere in between, there's a tiny gap you've got to slip through. Cerkio GD is pure reflex training dressed up as a game. A ball moves through rotating circles, each one with a narrow opening that shifts as it spins. You guide the ball through the gap. Miss it? You're done. Hit the edge? Back to the start. Each level cranks up the speed. The circles spin faster. The gaps get smaller. Your reactions get pushed until you're either in the zone or staring at a game over screen wondering what happened. Minimalist visuals. No distractions. Just you, a ball, and a growing need to prove you can handle what's next. It's the kind of game that makes you hold your breath without realizing it. HTML5, browser, no downloads.
