1. Face the outlaw
Slip Sanders, Granny Gravel, Coyote Cal — every town has its own gang of funny cartoon rivals waiting on Main Street at high noon.
Kids ages 6–10 out-draw cartoon outlaws with math: the right answer flies across Main Street and knocks the outlaw's hat clean off. Free, no ads, and it never collects a single byte about your child.
30 seconds. One outlaw. One math problem. You'll get it.
The whole game is built around one 30-second loop kids can't put down — it's the duel at the top of this page, so try it yourself.

Slip Sanders, Granny Gravel, Coyote Cal — every town has its own gang of funny cartoon rivals waiting on Main Street at high noon.
When the noon bell rings, the question appears. Tap the right answer before the outlaw works it out and the number itself flies across the street — hat off, outlaw in the water trough. Miss, and you'll be eating dust.


Stars and XP open new towns and boss showdowns. Five frontier towns stand between your kid and the mysterious Sheriff's Ghost — and his golden badge.
Behind the slapstick is a curriculum-aware mastery engine. It rates your child's skill on every operation separately — addition, subtraction, multiplication, division — and serves each duel at exactly the right difficulty, from first sums at age 6 to multi-step problems at age 10.
If a topic hasn't been covered at school yet, the engine notices the pattern and holds that topic back instead of frustrating your kid — then gently re-introduces it later. You can also switch individual math topics on or off yourself, behind a parent gate, and a built-in dashboard shows how each skill is progressing.
Practice is framed as a daily goal and a win streak — never a punishment. Kids think they're dueling outlaws. Hit the daily goal and they've quietly solved 25+ problems — and most kids don't stop at the goal.

Buck and Sierra ride from day one — and more of the posse is already saddling up for the next trail.
A hand-painted overworld trail leads from a sleepy first town to a spooky-friendly showdown with the Sheriff's Ghost. Each town brings tougher outlaws, new math skills, and a boss duel guarding the road out.
