Goal: Remove all 28 pyramid cards by pairing them to sum to 13.

Pairs that make 13: K alone · Q+A · J+2 · 10+3 · 9+4 · 8+5 · 7+6

Available cards: Any pyramid card with no cards overlapping it from below, plus the top card of the waste pile.

Stock: Click the face-down deck to flip one card to the waste pile. When stock is empty, click to redeal (2 redeals allowed).

Selecting: Click one card to select it (gold border), then click its pair. Kings remove immediately on click.

Win: Clear all 28 pyramid cards — the remaining stock/waste don't need to be cleared.
