Free forever: rules, tiles, the card, and the solver. Members unlock the training loop — practice drills, a card-family map, spaced review, and your progress dashboard.
New here? This same form creates your account (username 3–20 chars, password 6+). First 150 members get founding pricing.
Members-only lessons — decision drills, a card-family map (where each family lives on the 2026 card), and spaced review — appear here once you subscribe. Non-members see a locked state.
Billing is shown in mock mode for local preview. Production checkout runs through a Merchant of Record (Paddle / Lemon Squeezy) which handles U.S. sales tax; no card data touches this server.
