How Trefoil plays
Four Aces start on the foundations. The other 48 cards form sixteen face-up fans of three. Only top fan cards move; they build down in the same suit or advance a suit foundation. An empty fan cannot receive a new card.

Trefoil begins by moving all aces to foundations, then deals the remaining cards into sixteen three-card fans. Build foundations up by suit, build fans down by suit, and use two redeals when play stalls.
Select a top card, then pick a highlighted destination. Redeal unlocks when no moves remain.

Every suit foundation is ready for a Two from the start. Compare which top-card move exposes a Two and what that move covers. The two redeals occur only when no normal move remains.
