Quick Calculator

Quick Calculator is a speed-math game. You get 45 seconds. How many can you solve?

THREE MODES
- Mental Math: single digits, double digits, times tables, division, decimals, and primes-only
- Here's the Bill: work out the tip before the table notices, from whole dollars down to exact cents
- Dice Check: total the roll at a glance, from a pair of d6 up to a full d4/d6/d8/d10/d12/d20 set

SIX DIFFICULTIES
Easy through Impossible, each a preset bundle of rules that change how a round plays and what it pays. Or build your own in Custom.

UNLOCKABLE MODIFIERS
Earn career XP to unlock rule changes. Rush cuts the clock. Hidden makes the problem vanish before you answer. Cold Streak kills your multiplier. Sudden Death ends the round on a single mistake. Harder rules pay more.

STREAKS AND TIME
Right answers buy you time and build a score multiplier. Wrong answers cost you more than they give.

LOCAL LEADERBOARD
Track your best on all 18 levels against the developer's score, and see how many you have beaten.
