Auto concentration (オート神経衰弱, Ōto shinkei suijaku) is a card game in which a player matches pairs in order to clear a field of cards. It is a mini-game in Suikoden.
The object of the game is to match up all the pairs within a predetermined time limit. When a pair is matched, surrounding cards are also flipped over, with any matches flipping their surrounding cards and so on. This chain reaction allows games to pass swiftly.
Georges challenged the hero to this game during the Gate Rune War and joined the Toran Liberation Army when he lost. His cards had pictures of members of the Liberation Army on them. This may have been a custom order.
