How to play
You complete Flipper 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.
- Flipper opens from a versioned seeded position built for Occupying any of seven cells flips the top card of its paired tableau pile face down and locks that pile; emptying the cell flips the card back and restores access. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
- Every Flipper action is checked against the current board, available material, and this defining restriction: Occupying any of seven cells flips the top card of its paired tableau pile face down and locks that pile; emptying the cell flips the card back and restores access. Invalid, stale, or post-terminal actions leave the position unchanged.

Strategy tips
- A practical Flipper plan is to preserve several legal continuations around Occupying any of seven cells flips the top card of its paired tableau pile face down and locks that pile; emptying the cell flips the card back and restores access. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
- A common Flipper error is to ignore the boundary rule that Occupying any of seven cells flips the top card of its paired tableau pile face down and locks that pile; emptying the cell flips the card back and restores access. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
- Near the end of Flipper, 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.
