Boxed
Real AMC 10 and AIME problems. Solve today's five, practice at your level, or run a live round for your math team.
Daily five
Five problems a day, the same for everyone, climbing from AMC 10 #1–5 up to #21–25. One try each. Share your score and keep a streak.
Practice
Pick the difficulty and topics you want and keep going for as long as you like. After each problem you see the answer and a link to full solutions.
Live game
The host puts problems up on a projector, everyone answers on their own phone, and a leaderboard rewards right answers, fast ones, and whoever gets there first. The host picks the difficulty and topics before each problem.
