MathRise vs Calcul Mental Challenge

Get faster at mental math. Face players at your level in 10-problem duels, train at your own pace and track your progress. Challenge your friends or take on the Daily Challenge. LIVE DUELS - Same problems, same clock: the fastest correct answers win. - You're matched with players at your level, and every duel moves your Elo rating, just like chess. - Climb the tiers from Rookie to Grandmaster and see where you stand in your country and worldwide. PRACTICE AT YOUR OWN PACE - No clock, no pressure: addition, subtraction, multiplication, division, times tables, squares, percentages, fractions. - Difficulty adapts to you: easier after two misses, harder when you're on a roll. Your mistakes wait for you in a "To review" list. - Warm-up: a 90-second arithmetic sprint to get your brain going. TRACK YOUR PROGRESS - Every ranked duel gets a performance rating, and "My progress" charts your curve duel after duel. - Daily Challenge: one try, the same 10 problems for everyone. Where will you land today? - Daily quests and streaks: three goals a day, and a streak freeze protects your run when you miss a day. FRIENDS & GROUPS - Add friends by username and challenge them in one tap: problems are calibrated between your two levels. They beat your time? Rematch. - Challenge anyone with a link or a code, and share your score card. - Group sessions: open a room, show the code, and everyone plays the same set with just a first name, no account needed. Podium at the finish. FOR TEACHERS Run a live mental math session with your class: one code on the board, up to 100 students on the same problems, no student accounts or emails. Each student sees only their own score; you see the full standings.
