How to play

You complete Quartets when all thirteen rank quartets are assembled in the cells and removed, leaving no card in stock or tableau. The full Quartets position determines the outcome; visual shortcuts never replace the documented Quartets terminal rule.

  • Quartets begins with face-up working columns, four empty quartet cells, and a stock that reveals additional cards while no conventional foundations are present. The Quartets deal identity and PySolFC Quartets v1 are stored together. Restarting Quartets reproduces this opening exactly.
  • During Quartets, you build one rank up or down in alternating colours, move legal sequences, place cards into cells, and remove four cell cards only when ranks match. The Quartets engine rejects profile violations, unavailable material, and every action attempted after Quartets reaches a terminal result.
  • You complete Quartets when all thirteen rank quartets are assembled in the cells and removed, leaving no card in stock or tableau. The full Quartets position determines the outcome; visual shortcuts never replace the documented Quartets terminal rule.

Strategy tips

  • A reliable Quartets plan is to collect a rank only when all four copies are accessible and use reversible up-or-down tableau links to expose the missing suit. A Quartets hint is legal and deterministic. The next Quartets hint exposes one bounded action; it never claims a forced Quartets win.
  • A costly Quartets mistake is to fill cells with three promising equal ranks and an unrelated blocker; no individual cell card can be cleared before a complete quartet forms. Undo supports studying that Quartets decision, while restart preserves the original seeded Quartets opening.
  • In the Quartets endgame, identify the last two ranks, keep their copies on separate tableau tops, and clear one quartet before loading cells for the other. Check every remaining Quartets action before committing because its terminal rule is enforced immediately.

Quartets uses the independently implemented PySolFC Quartets v1 profile (R301). Quartets is a complete deterministic browser game built around tableau sequences that may rise or fall in alternating colours and four reserve cells that clear only as a complete equal-rank quartet.

Questions players ask

What makes Quartets a separate game?

Quartets uses tableau sequences that may rise or fall in alternating colours and four reserve cells that clear only as a complete equal-rank quartet. That rule belongs to the Quartets engine and storage identity rather than a cosmetic preset.

Which edge rule matters most in Quartets?

The four cells clear atomically only when all four contain the same rank; suit and colour do not alter that removal test.

How is a Quartets position reproduced?

Quartets records its game ID, rules version, and seeded deal identity. Those Quartets values recreate the same opening without a server request.
