Baker's Dozen

Thirteen open columns that build down in any suit one card at a time, empty columns that take nothing back, and a King sink left to the player instead of the deal. 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- Thirteen columns of four, all face-up. Columns build **down in any suit**, **one card at a time**.\n- An **emptied column stays empty** — nothing may be placed back into it. There is no stock and no redeal.\n- **Sink the Kings first.** A King outranks every card and an empty column takes nothing, so a King can never move, and whatever sits under one is stuck for good. By tradition you begin by sliding each King to the bottom of its own column: arm **ORDER** (press **D**) and drag it down. This is a convention you apply yourself, not a rule — skip it for a much harder game.",
