Play Mahjong Keiji Online

Konami released Mahjong Keiji for the Game Boy Advance in 2005, a time when the handheld was packed with experimental and niche titles. It stands out as a detective adventure that cleverly uses mahjong solitaire as its core mechanic, blending puzzle solving with light storytelling in a way that felt fresh for the system.

You play as a detective who investigates crime scenes by clearing mahjong tile layouts; each matched pair removes a tile and gradually uncovers clues or evidence hidden beneath. The main objective is to solve various cases, which range from petty thefts to more elaborate conspiracies, by fully clearing each board to reveal the full picture or key item. Signature mechanics include the risk of getting stuck if you make poor matches early, requiring strategic tile selection, and the integration of story elements that change depending on how efficiently you clear puzzles. The pacing is methodical, and the difficulty can spike on later boards, demanding careful observation. It feels satisfying to peel back layers of deception one tile at a time, turning a classic game into an investigative tool.
