In 2014, Korea Boardgames released the 2-4 player spellcasting game Abraca... what? from Gary Kim. In this game, you have spells in front of yourself that you can cast, but you see only the spells held by opponents, so you have to figure out which spells you can cast to take them out — and if you cast the wrong spell too often, you lose the game. (Here's a video overview recorded at SPIEL '14.)
Twelve years later, at Tokyo Game Market in May 2026, Kim and Korea Boardgames will debut Abraca Who?, a deduction game for 3-6 players who once again need to figure out something about themselves in order to win. Here's an overview:
Players are guests at a haunted house party who have been cursed by a ghost, causing them to lose their sense of identity. To lift the curse, you must navigate the chaos and collect mysterious stones while trying to figure out who you are.
On your turn, you either Investigate by naming your hidden card to trigger powerful abilities or Duel an opponent to deal damage based on your card's power. Since you can see everyone's card but your own, you must use deduction and the growing pool of revealed cards to stay alive.
The game ends instantly when a player collects seven mysterious stones, which are earned by winning duels, successfully investigating, or being the last survivor of a round.
Korea Boardgames will have a second new deduction title at Game Market Spring 2026: Woojin Yang's Jusayo. Here's an overview of this 3-5 player card game:
Your goal is to avoid playing your own cards by forcing others to play theirs. Players collectively move a figure around the circular color board, and on your turn, you must either play a card matching the current color, request a card from an opponent ("Jusayo", which is Korean for "Please give it to me"), or call someone out ("Bet you can’t"). Double-color cards immediately shift the figure to a new space, potentially disrupting the next player's plans.
The tension lies in the risk of elimination: If you request a card and the target cannot play, or if you call someone out and they can play, you are knocked out of the round. Conversely, being called out when you have no playable cards also results in elimination. The round continues until only one player remains, with this player then flipping their victory card to the "flower" side. The first person to survive two rounds wins the game.
