The Brain Map
Watch every fact turn green.
Each kid gets a Brain Map of all 121 addition facts, and all 121 times facts too. Scroll to fast-forward through six weeks of practice.
Skill power
See their skills grow, week by week.
The power web turns every adding skill into one shape. The further it reaches, the stronger the skill.
For grown-ups
Fun for kids. Clear for parents.
Memory, not counting
A fact only counts as known when it's right and fast. The speed bar adjusts to how quickly your kid taps, so it measures memory, not typing.
Brings back the tricky ones
Missed facts come back in the same session. Known facts return days and weeks later, so they stick for good.
Starts where they are
The first rounds find what your kid already knows, so nobody drills facts they've already got down.
Real animal science
Fights use each animal's real size, speed and weapons. Every battle ends with true facts and a real photo.

Questions
What parents ask.
What ages is it for?
Kids learning their addition facts (up to 10 + 10) or times tables (up to 10 × 10), usually ages 5 to 10. You choose adding, times, or both for each kid.
How long does a round take?
A round is 10 facts, so just a few minutes. Short practice most days works best, and the coins keep kids coming back for more.
Are the fights violent?
It's cartoon comic-book action, like a nature show come to life: swipes, chomps, and knockouts with cartoon stars. No blood, no gore. Every fight ends with real facts about both animals.
Is it safe for my kid?
There are no ads, no chat, and no real-money shop. Coins can only be earned by doing math, so there's nothing to buy inside the game.
What do we need to play?
Any device with a web browser: iPad, tablet, Chromebook, phone, or computer. Nothing to download. Progress saves to your account, so kids can switch devices.
How does the free week work?
You get 7 days of everything, free. You add a card through Stripe, our payment company, but nothing is charged until the free week ends. Cancel anytime before then and you won't pay a thing.
Can we keep what we played on the free game?
Yes. Start your free week on the same device, and every player from the free game comes along, coins, animals, Brain Map and all.
What if we cancel?
Cancel anytime from your account in a few taps. You keep playing until the time you've paid for runs out, and your kids' progress stays saved in case you come back.
Can more than one kid play?
Yes. Add a player for each kid. Every kid gets their own Brain Map, coins, and animals.
