How to play
The winning condition for Valentine is precise: all four columns finish as ordered King-to-Ace suit runs. No hidden solution values are printed to justify the result; the rules engine validates the submitted position.
- Before the first move in Valentine, identify which marks are givens and which controls are decisions. Four suit columns are arranged King down to Ace through a deterministic collect-and-redeal operation that may be repeated without a preset limit. The browser stores that distinction with the seeded opening so a restart never changes the puzzle or deal.
- Use the live board controls to change one legal decision at a time. Four suit columns are arranged King down to Ace through a deterministic collect-and-redeal operation that may be repeated without a preset limit. The runtime validates the resulting state before it records a move or opens a new undo branch.

Strategy tips
- Use each deterministic collect-and-redeal pass to improve the earliest break in a King-to-Ace suit column, since later cards cannot repair an inversion above it.
- Unlimited redeals do not mean random improvement; repeating the same collection without changing a blocking transfer recreates the same unsuccessful order.
- Use undo to compare the last branch if two completions look plausible, then recheck the exact requirement: all four columns finish as ordered King-to-Ace suit runs. A locally attractive move can still break a distant constraint.
