Math Games: Numinja
Slice the fruit, learn math
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Read the sum. Slice the answer.
Math Games: Numinja turns arithmetic practice into a fruit-slicing game. A question appears at the top, three numbered fruits fly up, and you swipe through the one that answers it. The right fruit builds your streak. A wrong fruit, or a wave you let fall, costs a heart and shows you the answer. You get three hearts.
WHY IT WORKS
• Every question is written on the spot, so there is nothing to memorize
• The wrong answers copy real mistakes, like a dropped carry or a swapped digit, so guessing costs you
• Runs speed up gently after the first three waves, and the streak multipliers reward staying sharp
• Mental arithmetic under a little time pressure is a different skill from arithmetic on paper, and this trains that one
FIVE TIERS
Starter: adding and taking away within 20
Easy: two-digit sums, and the 2, 5 and 10 tables
Medium: times tables to 12 × 12, division, three-digit sums
Hard: two-digit multiplication, fractions, percentages, negatives
Expert: big products by estimate, signed numbers, long division
A GENTLE START
The first play is a three-swipe lesson with no hearts and no score. Results show what you got right, your accuracy and one question worth a second look.
BUILT FOR SHORT SESSIONS
One thumb, portrait, and no sign-up: nothing to create, no password to remember. A run is a minute or two, Numinja keeps your best score for each tier on your phone, and it plays anywhere, with or without a connection.
Ads appear between runs. Reviving a finished run once is optional and ad-supported.
Ratings & Reviews

New: Remove ads. One purchase in Settings ends the ads between games, and Restore brings it back on your other devices with the same account. The optional extra-heart video is still there when you want it.
