Zero In: Number Puzzle

Zero in on the target. Combine six numbers with + - x / before the ring runs out. Ten levels free, then one purchase unlocks the rest.

Zero In is a race against the clock.

Every level gives you six numbers and a target. Drag two numbers into a row, pick an operation, and use the result to build toward the target. Hit it exactly for the full bonus, or land close for a smaller one. The ring around the target is your timer, and it does not wait.

TRY IT, THEN OWN IT The first ten levels are free to play for as long as you like. One purchase unlocks the rest of the campaign for good. No subscription, no advertising, nothing else to buy.

THREE TIERS, ONE LONG RUN Ten Easy levels teach the rhythm. Finish them to unlock Medium, then Genius, where the timer is shorter and the near range is tighter. Your score carries across the whole run.

EVERY PUZZLE IS SOLVABLE Each one is generated with a verified solution. Stuck? Ask for a hint, or reveal the solution afterwards and see the idea behind it.
