Draft from shared stacks

Four columns sit between you and your rival. Tap a top card to play it. Peeks below show what comes next — so math card games here are about sequencing, not luck alone.

Buffs, debuffs, and extras

Blue cards grow your pile. Red cards cut or steal from theirs. Purple cards can grant extra moves so you chain a multiplier into a steal before the turn flips.

Honest about the “math”

If you want pure times-table drills, look elsewhere. Outnumber uses math as the language of conflict — readable numbers, strategic drafting. Perfect if you like card games with a numerical twist.

Quick answers

What makes Outnumber a math card game?
Every card applies a numeric effect — add cash, multiply, boost %, divide, or steal. You draft those cards from shared columns like a card game, then win on stack size.
Are there free math card games online?
Yes. Outnumber runs free in the browser with no download. Play against the CPU or another person locally or online.
Is this like multiplication flash cards?
No. Flash cards test recall. Outnumber is a duel: you choose which card to take knowing your opponent gets the rest of the column later.
