How to play
You complete Four Stacks when every card reaches the ordered tableau 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.
- Four Stacks opens from a versioned seeded position built for There are no foundations: four thirteen-card packets must be rebuilt through six empty work piles into four complete alternating-color King-to-Ace columns. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
- Every Four Stacks action is checked against the current board, available material, and this defining restriction: There are no foundations: four thirteen-card packets must be rebuilt through six empty work piles into four complete alternating-color King-to-Ace columns. Invalid, stale, or post-terminal actions leave the position unchanged.

Strategy tips
- A practical Four Stacks plan is to preserve several legal continuations around There are no foundations: four thirteen-card packets must be rebuilt through six empty work piles into four complete alternating-color King-to-Ace columns. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
- A common Four Stacks error is to ignore the boundary rule that There are no foundations: four thirteen-card packets must be rebuilt through six empty work piles into four complete alternating-color King-to-Ace columns. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
- Near the end of Four Stacks, recount the remaining obligations needed until every card reaches the ordered tableau 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.
