The Cooler

A cooler is the house's answer to a winning streak: a deck somebody has seen to, or the man they sit down across from you when the night has gone your way for too long. Tic-tac-toe is a solved nine-move game, so the board here works as a damage engine rather than a win condition.

How it plays

  1. A line is exactly three cells and a deck is 52 cards, so every completed line is scored as a three-card poker hand. Seven, eight and nine of spades is a straight flush; it does 936 damage.
  2. Every card pulls two ways at once: where it goes, for blocking and forking, and what it makes, for poker value.
  3. Eight rooms of four fights: three regulars and a boss. The same faces keep turning up, deeper in the building, but every room scales them and hands its boss a different rule to break.
  4. Clearing a room grants max HP and a full heal, a charm slot every two rooms and a hex slot every three. Every run draws a seed, and the seed shuffles which boss breaks which rule.
