ZeroIn: Time Challenge

ZeroIn is built on pure timing: easy to learn, hard to master. The clock runs; your only job is to stop it exactly on target. The closer you get, the more stars you earn.

318 LEVELS, RISING DIFFICULTY
Levels were redesigned from scratch. No dead time between rounds — every phase introduces a new mechanic.

THREE GAME TYPES
• Math — the target time is the answer to a problem. If it's 3 × 2, stop the clock at 6.00.
• Time estimation — the clock is hidden; only your inner sense of time.
• Vanishing number — digits show for two seconds, then fade away.

ONLINE TABLES
• Real-time races with up to 12 players
• Invite a friend with a link — they land straight at your table
• Empty lobby? Start against bots right away, no waiting
• Rematches, trophies and rankings

START BUTTONS
