Tokens

Earn tokens.Trade them for real stuff.

Tokens turn into real rewards your parents put on the shelf. The big ones come from streaks, climbing and good thinking — not from racing through easy problems.

Leagues

Win the week byworking hard.

Every Monday you join a room of up to ten. The tokens you earn that week are your score — so it's about effort, not about already being the best.
