How to play
The winning condition for Phalanx is precise: the triangular exposure graph and waste are cleared into the four foundations. No hidden solution values are printed to justify the result; the rules engine validates the submitted position.
- Before the first move in Phalanx, identify which marks are givens and which controls are decisions. Fifteen nonbuilding reserves form a triangular phalanx, and only exposed reserve or waste tops may move to four suit foundations. 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. Fifteen nonbuilding reserves form a triangular phalanx, and only exposed reserve or waste tops may move to four suit foundations. The runtime validates the resulting state before it records a move or opens a new undo branch.

Strategy tips
- Trace which triangular reserve cards cover others and choose exposed moves that release two lower positions, since the nonbuilding reserves offer no rearrangement.
- Planning to park a card on another reserve is impossible; every exposed card must already have a foundation or waste-supported escape route.
- Use undo to compare the last branch if two completions look plausible, then recheck the exact requirement: the triangular exposure graph and waste are cleared into the four foundations. A locally attractive move can still break a distant constraint.
