Race real players in a live math speed test
Math Speed Test is a free online arithmetic drill built as a race. You and up to four other players get the same twenty questions and a two-minute clock. Every correct answer moves your car further down the track, and the first across the line takes the win.
How it works
Type your answer, press enter, move forward. Twenty questions, two minutes. If nobody else is online, bots fill the grid so there is always a race to run. No account required — play as a guest and start immediately.
What you get
Every finished race scores your problems per minute and updates your ELO rating, the same system used to rank chess players. Climb the ladder from Beginner to Grandmaster, appear on the global leaderboard, and earn money to unlock new cars in the Garage.
Who it is for
Students drilling mental arithmetic, teachers after a competitive classroom warm-up, and anyone who wants to calculate faster under pressure. The difficulty comes from the clock and the competition rather than the maths itself, so it works across ages and skill levels.
What is coming next
Addition, subtraction, multiplication and division races are all live, and you can create a private room to race your friends. Daily challenges to keep a streak going are next.
