About this game

Right or wrong? An equation appears: 7 × 8 = 54. Decide in a split second: swipe the card or tap. Math 99 has been played since 2015; now it's rebuilt from the ground up.

BLITZ
Time is a pool: every right answer adds time, every wrong one takes it away. Chain right answers into combos, hit fever mode at a 10 combo and double your points. New question types unlock as you play: "Which is bigger?", missing sign, missing number. Your best score this week is kept separately.

99 STAGES
Nine regions and 99 stages, from addition to division, from missing numbers to two-step problems. Earn three stars on each.

REPORT CARD & MASTERY PATH
Your speed and accuracy on every times-table fact, on a 10×10 report card. See your weak spots and work on them with untimed practice. The mastery path uses spaced repetition: each day you only review the facts that are due.

DUEL
Two players, one phone, the same question. The first right answer scores; a wrong tap loses a point. Give the stronger player a waiting time so players of every level can play on equal terms.

DAILY
The same questions for everyone, one try per day. Keep your streak going; miss a day and you can make it up the next. Want a reminder in the evening? Just switch it on.

CLASSIC
The original Math 99: a short time for each question, and the game ends at the first mistake.

FOUR THEMES
Ribbon, Chalk, Neon and Notebook, each with its own music, sounds and look. They unlock as you level up.
