## What is KOŁO?

KOŁO is a one-tap timing game built around a single moving bead, a narrow target, and almost no margin for error.

Tap when the bead crosses the target zone. Land inside the orange Perfect Core to build streaks and restore your margin. A normal hit keeps the run alive but tightens the zone. Miss, and the run ends.

As your run grows, the pace accelerates and the margin for error tightens. When a result is too close to call, Edge Check slows the moment down and reveals whether the bead truly touched—or missed by a fraction.

Features

• Simple one-tap controls
• Fast, replayable runs
• Increasing speed and shrinking margins
• Perfect streaks that restore the target
• Cinematic photo-finish Edge Checks
• Responsive sound effects and haptics
• Reduced Motion and High Contrast options
• No account required
• Play on iPhone, iPad, and Apple Watch

Easy to understand. Difficult to master.

KOŁO means “circle” in Polish.

One tap. Zero margin.
