About this game

ZeroIn is a stopwatch reflex game: the clock runs and you stop it exactly on target. Sounds easy — until the timer disappears.

300+ LEVELS
• Visible clock, vibration beats, fully blind timing and countdowns
• Vanishing digits that show for two seconds, then fade away
• Math targets: if it's 3 × 2, stop the clock at 6.00
• Time estimation: feel 7.35 seconds without seeing a single digit
