Blitzo: Quick Math

Blitzo turns mental math into an arcade game: 60 seconds to solve as many sums as you can, a daily streak to keep alive and leagues to climb.

CHRONO
60 seconds, all four operations mixed. It gets harder every 5 correct answers. Beat your record and climb from Bronze to Master.

ZEN
Practice with no timer, at your own pace:
• one operation, or all of them mixed
• times tables from 2 to 20
• your own table, for example 6 to 9 times 11 to 15
• a specific Chrono tier, unlocked once you have reached it

DUELS
Race an opponent on exactly the same sums and watch their progress live:
• a Rival at your level, even offline
• a real player online, live through Game Center; if nobody is free, the recorded game of a player at your level
• your Game Center friends, live or against their last game, without touching your Elo

KEEP IMPROVING
• Daily streak and reminder
• Statistics: your score curve, accuracy and time per operation, your weak spot highlighted
• On-device leaderboard and Game Center Chrono and Elo leaderboards, among friends and worldwide
• Home Screen widget

COMFORTABLE
• Answers are accepted as soon as they are right
• Hardware keyboard support on iPad
• Type left to right, or right to left like written column sums
• Dark mode, large digits, in English, French, German and Italian

LIVES AND BLITZO PRO
Each Chrono game or Duel costs a life; lives refill on their own, and a new record gives yours back. Zen and Duels with friends are always free. Blitzo Pro, a one-time purchase with no subscription, gives unlimited lives, removes ads and unlocks every Zen tier.
