Pyramid 21 — click pairs that sum to 13

Click deck (top-left) to draw a card. Kings (K = 13) remove alone.
Rules: Remove two exposed cards whose numeric values add to 13. Face values: A=1, J=11, Q=12, K=13. You may draw from the deck (top-left) to the waste (next to it) and pair waste with exposed pyramid cards. Reset restarts the game.
