BubbleTots
Ages 3–5 · Gr K–K Level 1
A fill-the-potion game for ages 3–5: draw bubbles from a see-through bag to fill Bub’s potion. Draw another for more — or pour what you’ve got in to keep it safe. A 💥 pop only spills HALF your bubbles this round (never all, and never your potion), so it’s always gentle. The keep-going-or-stop choice, felt through play. No losing. On-device; nothing leaves your device.
Play BubbleTots →
BuilderTots
Ages 3–5 · Gr K–K Level 1
A first building game for ages 3–5: Timber the beaver builds cozy things from parts! Each thing has a little recipe — a birdhouse needs 2 logs and 1 leaf.

RollTots
Ages 3–5 · Gr K–K Level 1
The very first counting game, for ages 3–5: Puff the frog is waking up the pond! Roll the big die, count the dots, then tap the lily-pad with that many fish — it wakes up with a splash. No reading needed (tap to hear it), no score, no losing — just a happy, wide-awake pond.

TeeterTots
Ages 3–5 · Gr K–K Level 1
A see-saw tips down on the heavier side — can you make it level? TeeterTots gives your littlest learner a balance beam and a handful of blocks: tap the one that makes both sides the same. It says everything out loud (no reading needed), the blocks are big to tap and easy to count, and there is no way to lose — a wrong tap just says "try another." Balancing the see-saw is the very first taste of what equals means. On-device, no account. Ages 3–5.
Play TeeterTots →
TrayTots
Ages 3–5 · Gr K–K Level 1
A take-turns fruit game for ages 3–5: a tray of fruit appears, and you take ONE for your rainbow basket — then leave the rest for your friend Juniper. Collect one of each colour to fill your rainbow.

Play CratePals →
DeckPals
Ages 6–8 · Gr 1–3 Level 1
A build-your-own-bag game for ages 6–8: your jar of tokens is see-through, so you always know what’s inside. Draw a handful, then make the jar better — buy a shiny token (you’ll draw it later!) or throw a dull pebble away forever. Watch the odds change as you build. On-device; nothing leaves your device.
Play DeckPals →
PollPals
Ages 6–8 · Gr 1–3 Level 1
Ask the class a question, tap in the answers, and a bar graph draws itself. The tallest bar is the favourite — but before you asked, you didn’t know. That’s the big idea: data is MADE, not given. Read the graph (which won? how many more?), then make your own in the Bar-graph lab. A tiny, deterministic data game, no internet. Ages 6–8.
Play PollPals →

TrekPals
Age 6 · Gr 1 Level 1
A calm number-fact journey for ages 6–8 — the friendly opposite of the battle-and-paywall math apps. Trek's caravan walks one oasis forward each time you know a fact by heart; Dot the fennec SHOWS every new fact as a ten-frame or an array first, so it means something before you memorize it. Adaptive on-device practice that never rushes, never fails you, and never takes a step back — no battles, no timers, no limits. Meet a desert friend at every third oasis.
Play TrekPals →
BasketPals
Ages 6–8 · Gr 1–3 Level 2
A push-your-luck dice game for ages 6–8: Pika the beaver stacks hay for winter! Roll the two dice and gather hay into your basket — but a 7 tips it over. Bank when you feel lucky enough; the biggest haypile wins. Spilled hay never wastes — it lands in the meadow for the next friend to scoop. Discover, by playing, that 7 comes up most.

Ages 9–14.
Play CalendarForge →
SpokeForge
Ages 10–13 · Gr 5–8 Level 3
How does a bicycle turn one push of your legs into a wheel spinning four times over? Gears. The front teeth divided by the rear teeth is the gear ratio — how many wheel turns you get per pedal — and it sets everything: how hard the pedals are, how far one push carries you, how fast you go. Predict the ratio, then build your own gear in the workshop. Real, tiny, deterministic maths — no internet. Ages 9–14.

FlickForge
Ages 9–13 · Gr 4–8 Level 3
The physics of the flick, for ages 9–14: predict where a struck disc will come to rest — after it banks off a rail (angle in = angle out), slows to a stop (friction), or passes its momentum to another disc (the carrom strike). You call the landing band, then the deterministic sim reveals the path so you can reconcile. Plus a free table to experiment on. On-device; nothing leaves your device.
Play FlickForge →
CreaseForge
Ages 10–13 · Gr 5–8 Level 4
Every time you fold a piece of paper, you are doing geometry: the crease is a mirror, and whatever was on one side lands as its reflection on the other.

Play MosaicForge →
SextantForge
Ages 10–13 · Gr 5–8 Level 4
How did sailors find their way with no GPS? They read the sky. The North Star’s height above the horizon IS your latitude; a clock set to home turns your local noon into your longitude at 15° an hour. Measure Polaris, predict your position, then check it in the Navigator’s lab. Real, tiny, deterministic maths — angles and time — no internet. Ages 9–14.
Play SextantForge →

VectorForge
Ages 15–18 · Gr 9–12 Level 5
Linear algebra you can see, for ages 15–18. A 2×2 matrix is a transform of the plane — rotate, stretch, shear, reflect, flatten. Predict where a point lands, then watch the matrix move a shape: the determinant is how much it scales area, and the eigenvectors are the directions that don’t turn. It’s the on-ramp to the maths behind AI — a matrix is a neural layer. On-device, exact arithmetic.
Play VectorForge →
OddsForge
Ages 15–18 · Gr 9–12 Level 4
Weigh the evidence: how surprising is a streak if the honest odds held? Read one-sided p-values off the binomial tail — and see how peeking until it “looks significant” manufactures a false alarm. Ages 15–18.
Play OddsForge →
PrimeDojo
Ages 15–18 · Gr 9–12 Level 4
Multiply two primes: easy. Un-multiply their product: nearly impossible. That one gap is why your bank is safe. PrimeDojo walks you from clock arithmetic to a working RSA key you build, encrypt with, decrypt with — and then BREAK by factoring, all by hand and all on your device. Predict each step, then watch the maths. Ages 15–18.
Play PrimeDojo →
RiskDojo
Ages 15–18 · Gr 9–12 Level 4
A rare disaster you can’t afford, swapped for a small cost you can — that trade is all insurance is, and it’s just maths. RiskDojo builds the whole idea from expected value up: the fair premium, the deductible, and the law of large numbers that lets a pool cover a rare big loss and still break even. Predict each number, then reveal the worked step — and run a pool yourself to watch adverse selection break it. Ages 15–18.
Play RiskDojo →
ApprenticeDojo
Ages 15–18 · Gr 9–12 Level 5
The trades run on maths every apprentice must get exactly right — because the number IS the safety. Ohm’s law sizes a wire so it won’t overheat; a cooling load sizes an air conditioner; a ¼-inch-per-foot slope makes a drain actually drain. Predict the calculation, reveal the working and the code behind it, then run the numbers yourself in the Trade lab. Real electrical, HVAC and plumbing maths — no internet. Ages 15–18.
Play ApprenticeDojo →
CentralForge
Ages 15–18 · Gr 9–12 Level 4
You are the central bank. Set one lever — the policy rate — and steer inflation and jobs, but everything you do arrives with a lag. Hike to cool prices and inflation barely moves for a year; hold too long and you over-tighten into a recession; face a supply shock and there is no clean move at all. Predict the economy, then run it yourself. All exact, all on your device. Ages 15–18.
Play CentralForge →
OrderDojo
Ages 15–18 · Gr 9–12 Level 4
Before you trust a number, run three checks. Orders of magnitude: a "100× better" claim is a two-order leap — is that plausible? Dimensions: compute kinetic energy with v instead of v² and the units reveal you got momentum, not energy. Calibration: being 90% sure and wrong costs almost the maximum. Predict the check, then run it on your own claims. All exact, all on your device. Ages 15–18.
Play OrderDojo →
BottleneckForge
Ages 15–18 · Gr 9–12 Level 5
Find the step that really limits the outcome — predict, then let the math show you. Amdahl’s law, survival funnels, and how many shots it takes. For teens.
Play BottleneckForge →

Predict the limit, the slope, the area — then a real engine computes it and shows the rule. Precalc into calculus, made intuitive. For teens.
Play CalcQuest →
InferForge
Ages 15–18 · Gr 9–12 Level 5
See the ideas AP Statistics students find hardest — the sampling distribution of the mean (the Central Limit Theorem) and what “95% confident” really means — by running the simulations yourself. Predict, then run 300 samples and watch. On-device, nothing leaves your device.
Play InferForge →
InsightForge
Ages 15–18 · Gr 9–12 Level 5
Proofs without words: reconstruct the argument a picture hides — then catch the pictures that lie.
Play InsightForge →
LocusForge
Ages 15–18 · Gr 9–12 Level 5

Play LocusForge →
NimForge
Ages 15–18 · Gr 9–12 Level 5
The mathematics of who wins, for ages 15–18: play Nim (and its last-token-loses twist), then let the engine reveal WHY a position is won or lost — the Nim-sum, Sprague–Grundy values, and the golden ratio hiding inside Wythoff’s game. Play, conjecture, and the engine checks every small position. On-device; nothing leaves your device.
Play NimForge →
PriorForge
Ages 15–18 · Gr 9–12 Level 5

Play PriorForge →
RatingForge
Ages 15–18 · Gr 9–12 Level 5
Build a rating system and watch it converge (and wobble). For teens: give six bots hidden true strengths, play a season, and watch Elo sort them — then change the K-factor and see the trade-off between fast and steady. Computed on-device; nothing leaves your device.
