Players don’t need an email. They just tap their name on this family’s devices. Use just a first name (one word, no spaces): friends’ families can see it.

Just a first name: one word, no spaces.

How placement and practice work

A short Power Check places your child in each category. Practice then stays on the topics they know but haven't mastered yet. A topic missed in a Power Check is marked Not yet; once everything before it is mastered, it opens for practice. Choose Always include to put a topic in the practice mix now, or Never include to leave it out. Re-check tests a topic again at the start of the next game.

Every subject added up. Tap a player to see their progress.
