How it works
They solve math problems
Every problem is generated, never repeated from a fixed list, and difficulty adapts as your kid plays. Missed problems come back for review. 16 skill toggles, from addition all the way up to basic algebra.
They earn a video
Rewards come from YouTube playlists you choose (starter packs included). Videos auto-play with no controls: no clicking away, no recommendations. When the video ends, it's back to the math problems.
You stay in control
A PIN-gated settings page tunes skills, playlists, and the target percentage of time spent doing math. A progress page tracks problems solved, minutes of math, minutes of video.
No grade levels. No assumptions.
Most math apps assume skills arrive in a fixed order. Plenty of kids, especially neurodivergent kids, aren't built that way. This game was designed for exactly that.
Every skill is its own switch
16 independent toggles. One kid races ahead in multiplication while easing into word problems; another crunches big numbers but isn't touching fractions yet. Enable exactly the mix that fits, and difficulty adapts within that mix.
The same loop, every single time
Solve, watch, back to solving. The progress bar shows exactly how many problems until the video. No surprise popups, no countdown timers, no ads breaking the rhythm.
Rewards that actually motivate
The prize isn't points or badges. It's the videos your kid already loves. Their interests become the engine.
Why this exists
My brother was just starting math when I built him the first version of this game in 2013, to practice addition and subtraction. We loaded it up with his favorite Sesame Street and Disney songs as the reward. He. loved. it. (We still sing some of those songs together.)
The game grew with him: multiplication and division, then fractions, decimals, negatives, and algebra, and every skill became its own independent switch. His pace. His mix. His videos.
More than a decade and 130,000 problems later, he's still playing.
It's a one-person project: I design, build, and run every piece of it. Now it's open to every family, free.
Built for parents' peace of mind
Everything a grown-up controls, in one PIN-gated place.
Your playlists, only your playlists
Rewards are drawn exclusively from playlists you've added. Start with curated packs or swap in your own.
No ads, nothing to buy
No ads in the game, no in-app purchases, no upsells aimed at your kid. Free.
Your kid's data stays boring
Kids don't even get logins; one parent account per family. We collect gameplay stats to run the game and nothing else.
Nothing to install
Runs in the browser on laptops and tablets. No app store, no updates to manage.
Common questions
What ages is this for?
Roughly 5–13, but the game thinks in skills, not grades. The toggles run from simple addition up through fractions, decimals, negatives, percentages, multi-step problems, and starter algebra, and difficulty adapts automatically inside whatever you enable.
My kid is autistic, has ADHD, or just learns differently. Will this fit?
It was built for exactly that. My brother's skills never matched a grade level and he thrives in routine. Nothing here assumes normative grade level math - every problem type is an independent toggle and word problems are optional. The gameplay is predictable and the rewards are consistent.
Is it really free?
Yes. It started as a gift for my brother and it stays free for families. Forever. No ads, no data selling.
Are the videos safe?
The game only ever plays videos from playlists that you, the parent, added. Videos play with no controls and no way to browse. When a video ends, the game returns to the math problems.
What do you collect about my kid?
Kids have no accounts and no logins. The parent account stores an email (for login) and gameplay events (problems answered, minutes worked and watched) that power the progress page. We don't sell data or run analytics or ad trackers. Two third parties are involved: Auth0, which handles the parent sign-in, and YouTube, which plays the reward videos.

Turn the YouTube battle into math practice.
It takes about five minutes to set up, and it's free forever.
