How to play
You complete Double Fives 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.
- Double Fives opens from a versioned seeded position built for One deck forms ten same-suit descending tableau lanes while the other appears in five-card batches; only cards left from those batches form the one-card-at-a-time final pass. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
- Every Double Fives action is checked against the current board, available material, and this defining restriction: One deck forms ten same-suit descending tableau lanes while the other appears in five-card batches; only cards left from those batches form the one-card-at-a-time final pass. Invalid, stale, or post-terminal actions leave the position unchanged.

Strategy tips
- A practical Double Fives plan is to preserve several legal continuations around One deck forms ten same-suit descending tableau lanes while the other appears in five-card batches; only cards left from those batches form the one-card-at-a-time final pass. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
- A common Double Fives error is to ignore the boundary rule that One deck forms ten same-suit descending tableau lanes while the other appears in five-card batches; only cards left from those batches form the one-card-at-a-time final pass. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
- Near the end of Double Fives, 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.
