The problem: drills get boring, puzzles do not
Multiplication tables and exact division are the base of almost every later math topic, yet drilling them can feel dull. A target game hides the drill inside a puzzle. While the student thinks about how to reach 47, he or she practices times tables without noticing.
The player uses each number once, but a division must come out exact. The game always checks that a solution exists, so a stuck player can skip the grid and see a possible answer.
How this number puzzle game works
- Tap a number, an operation, then another number. The result appears, so the player can reuse it right away
- Scoring rewards bold moves: 1 point for addition or subtraction, 2 for multiplication, 3 for division
- Using all four operations in one calculation earns the Coup Mathovore, worth 13 points
- A round has 10 grids, for up to 130 points
- Four difficulty levels, from targets of 10 to 40 up to targets of 60 to 300
- Timed modes: a 60-second sprint, a 3-minute marathon, the Défi Mathovore and a survival mode where each solved grid adds time
As players climb 6 ranks, from Novice to Grand Maître Mathovore, they unlock 12 badges and see statistics and a history of their recent calculations.
Who it is for
A student in Grade 5 (CM2) or Grade 6 (6ème) who knows the times tables can use Facile and Moyen to build speed. Older students in Grade 7 (5ème), Grade 8 (4ème) and Algebra 1 (3ème) will like Difficile and Expert, because targets reach 300 and the search for a path takes real thought.
Parents can play too. A round is short, so it works as a family game after dinner or a quick challenge on a car ride.
Getting started
The scoring rewards courage. A student who plays safe with additions earns little, while one who attempts a division and a multiplication in the same route sees the score jump. As a result, players move toward the harder operations, which are the ones that need the most practice. In addition, the game keeps your best round, best streak and fastest time, so there is always a personal record to beat.
- Install the app on your Android phone or tablet.
- Watch the short animated tutorial, which explains the game in about 20 seconds.
- Choose a level, usually Facile for a first round.
- Play 10 grids and read the worked example in the rules if you get stuck.
- Sign in with a Google account if you want your progress saved across devices.

Number games work best next to written lessons. After a round, look at the Grade 5 math or Grade 6 math pages for the topics behind the times tables and fractions. Besides, the game comes in English and French, and carries no advertising.
