Seahaven Towers

Ten same-suit columns that only a King may start, four cells, and staged moves over a deal that leaves two cards in the cells. Written as a design file, this is the whole game. Make a game explains every part of it.

  "description": "**Goal:** build all four foundations up from Ace to King, each in a single suit.\n\n- Ten columns of five cards build **down in the same suit** (a 6 of spades on a 7 of spades).\n- Four **free cells** hold one card each — two of them start with a card from the deal.\n- Only a **King** may start an empty column, so freeing your Kings is the opening problem.\n- A descending same-suit run can be dragged as a group, but only as far as free cells and empty columns could relay it by hand: **(1 + free cells) × 2 for each empty column**.",
