Build a food web. Watch it call your bluff.
This is a Classion game — where playing is the lesson and the test at once. Add a few species, hit run, and watch it read your reasoning back to you, exactly like it reads all 30 of your students.
it's live, not a screenshot — poke it →This is one game, shrunk to a taste. Classion is a whole library of them — genuinely fun games, built by game designers and teachers together, each one teaching a real idea and quietly showing you who's got it and who's faking.

Every "educational game" is a quiz in a costume. We threw out the quiz.
Game-based learning is exploding — and most of it is a worksheet with points, built by studios that bolt a lesson on at the end. We do it the other way around: educators and game designers build the idea into how you play, so the fun and the learning are the same move. You just felt it work.
A grade says a kid missed it. Classion says what they were thinking when they did.

Four wrong. But which four, and what idea broke? No clue. Good luck guessing what to reteach.

Maya — after one 15-minute game
Solid Builds real chains, producer to consumer, every time. The structure's there.
Shaky Thinks one big plant beats a varied web. Keeps betting everything on it — keeps getting wiped out.
Do this tomorrow: ten minutes on why variety survives a bad year, then hand her the survival challenge again. Beating it is the proof it stuck.
A game this good for everything you teach.
You just played one. We're building games at that level for the ideas kids trip on all year — from food webs to fractions to how a bill becomes law. Whatever you're teaching, there's a game coming that turns it into something they actually want to play.

Built to your scope & sequence, so it slots into the unit you're already on — no hunting.
If it isn't fun, it doesn't ship.
A game kids don't want to play can't teach them anything — or tell you anything. So every Classion game is built with veteran classroom teachers, playtested with real students, and reworked until it clears one bar: genuinely fun to play, honest about the concept, and full of signal about how each kid thinks. We're game designers, educators, and not-long-ago students ourselves — a quiz in a costume doesn't leave the room.
Free for teachers. Safe for kids.
- Free. Actually free. No trial clock, no seat math, no card on file. Teach a class, the classroom's on us.
- No logins for kids. They join with a code on the board. No emails, no passwords, no "I forgot mine."
- COPPA & FERPA, done right. We take the least data we can and guard what we keep. The boring part, handled.
- Standards baked in, not taped on. Each game is built around one NGSS or Common Core objective — the idea isn't glued to arcade filler.
