How to play
You complete Union Square when every card reaches the required foundation under this profile's rank, suit, direction, and access constraints. The engine evaluates the full position rather than relying on a visual shortcut or an unsupported solvability claim.
- Union Square opens from a versioned seeded position built for Each of sixteen lanes commits to ascending or descending same-suit construction after its second card and may never reverse that local direction. Its game ID, rules profile, and deal identity are stored together so restart recreates the same opening without a server request.
- Every Union Square action is checked against the current board, available material, and this defining restriction: Each of sixteen lanes commits to ascending or descending same-suit construction after its second card and may never reverse that local direction. Invalid, stale, or post-terminal actions leave the position unchanged.

Strategy tips
- A practical Union Square plan is to preserve several legal continuations around Each of sixteen lanes commits to ascending or descending same-suit construction after its second card and may never reverse that local direction. Use the deterministic hint to inspect one legal action, then compare how it affects the documented objective before committing.
- A common Union Square error is to ignore the boundary rule that Each of sixteen lanes commits to ascending or descending same-suit construction after its second card and may never reverse that local direction. Undo is useful for studying that decision, while restart deliberately preserves the original seeded position.
- Near the end of Union Square, recount the remaining obligations needed until every card reaches the required foundation under this profile's rank, suit, direction, and access constraints. Check the boundary rule after every final placement or transfer because terminal status is enforced immediately.
