How to play
You complete Trapdoor when every card reaches the foundation target while the profile's access, packet, and sequence restrictions remain satisfied. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim.
- Trapdoor opens from a versioned seeded position built for Eight cover reserves sit above eight alternating-colour lanes; each stock action first drops every occupied cover onto its paired lane and only then deals a fresh cover row. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
- Every Trapdoor action is checked against the current board, available material, and this defining restriction: Eight cover reserves sit above eight alternating-colour lanes; each stock action first drops every occupied cover onto its paired lane and only then deals a fresh cover row. Invalid, stale, or post-terminal actions leave the position unchanged.

Strategy tips
- A practical Trapdoor plan is to preserve several legal continuations around Eight cover reserves sit above eight alternating-colour lanes; each stock action first drops every occupied cover onto its paired lane and only then deals a fresh cover row. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
- A common Trapdoor error is to ignore the boundary rule that Eight cover reserves sit above eight alternating-colour lanes; each stock action first drops every occupied cover onto its paired lane and only then deals a fresh cover row. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
- Near the end of Trapdoor, recount the remaining obligations needed until every card reaches the foundation target while the profile's access, packet, and sequence restrictions remain satisfied. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.
