Mathzo

A mental arithmetic race laid out like a stadium scoreboard. Sums appear in huge numerals, you key the answer on a large number pad, and it is checked the moment the last digit goes in. A wrong answer flashes red and the same problem stays until you solve it. Plus — Race mode puts you in lane 1 against three pace bots, Steady, Swift and Blitz, whose progress moves live beside yours. Twelve problems to the line, in three divisions: Rookie with sums to twenty and tables to five, Pro with two-digit sums and tables to twelve, and Elite with three-digit sums and longer tables. Your finishing place and count of first places are kept for each division. Minus — Clock Rush gives you 60 seconds and every operation. The problems get harder as your tally climbs, and each miss takes two seconds off the clock. Times — The Ladder is a campaign of 30 rungs in five stages: addition, subtraction, times, division and a mixed finale. Rungs open in order, each with a par time. Finish inside par with at most one miss for three lamps, within 1.6 times par for two. Divide — The Daily set brings twelve mixed problems that are the same for everyone on that date. Your fastest time is stored for each day, and a week strip shows your streak. A history quiz asks ten questions from 27 facts about the people, symbols and tools behind mathematics, with a short explanation after each answer. Equals — Stats show problems solved, accuracy for each of the four operations, the clock record, first places and a table of your last 25 runs. Pale plus, minus, times and divide signs drift slowly behind every screen as an animated background; it can be switched off in Settings, along with haptics. The game plays fully offline with no account, in portrait or landscape.
