A playbook that fits your roster. Proof they understand it.

Proof, not vibes

How it works — and why it's provable

• "Mastered" means a player answered a play's last 3 questions correctly on at least 2 different days — one hot session never counts as mastery.

• Players join with a team code and pick their first name — no player accounts, no player email, no player passwords, by architecture (COPPA/PIPEDA posture).

• The fitting engine selects 12 calls from an 84-play validated library using deterministic, unit-tested rules on your roster's real depth chart — no runtime AI, so pricing never depends on per-use AI fees.

• Quiz answer options are re-seeded on every attempt, so a player can't memorize letter positions — she has to know the play.
