About Concentration Room

Platform: NES
Developer: Damian Yerrick
Year: 2010
Genre: Board and card, Puzzle
Players: 1-2
License: Homebrew

Damian Yerrick's card-matching game: flip two cards at a time and keep the pairs, on tables of 10 to 72 cards.

The story mode is set after an accident at a biochemical lab releases a neurotoxin; you have been quarantined after exposure, and the card game is what keeps you sane. There are also solitaire, two-player and versus-computer modes, with computer players from Preschool to Lab Technician. In two-player games the controller is passed between players.

It is part of Yerrick's Pin Eight NES software, with source included, and it appears on the first and fourth Action 53 multicarts.

How to play
