Sum Rush: Mental Maths Games

Sum Rush is mental maths that moves. Short, snappy puzzles, a clock that keeps you honest, and combos that make your brain feel fast. THREE KINDS OF PUZZLE • Solve: type the answer to a quick sum like 7 × 8 or 36 ÷ 4. • Compare: pick the sign that makes it true: greater than, less than or equal. • Fill the Gap: find the missing numbers and signs so the equation works. THREE WAYS TO PLAY • Beat the Clock: as many as you can in 60 seconds. • Sudden Death: one mistake and it's over, and the clock gets faster as your streak grows. • Endless: no clock, no score. Just puzzles. Pick Easy, Medium or Hard for each. CHAIN YOUR COMBOS Get answers right in a row and your combo climbs. Hold your nerve and watch the score jump. A LITTLE HELP WHEN IT'S TIGHT Earn coins as you play and spend them on abilities: • Time Freeze stops the clock for 5 seconds. • Skip moves past a stinker without breaking your combo. • Hint gives you a nudge on a Compare or Fill the Gap blank. WATCH YOURSELF GET QUICKER Personal bests for every mode, accuracy by puzzle type, your longest combo and your best Sudden Death streak. MADE TO FEEL GOOD Big, clear numbers, a satisfying number pad, gentle haptics and sounds you can switch off. Light and dark appearance. No account needed; your progress stays on your iPhone. Rounds are ad-free. Remove Ads is a one-time purchase if you'd rather not see banners in the menus either. Maths that tickles your brain. Ready? Rush.
