JantakuAR

Take Your Mahjong Table Anywhere. Jantaku AR is a Riichi Mahjong app that turns a real table into a shared virtual mahjong table using augmented reality. Place a marker on the table and scan it with your iPhone. A 3D mahjong table appears in AR, and up to four players can share the same table from their own seats. Tiles, discards, scores, and game progress are synchronized in real time. You can also practice alone in 3D mode without an AR marker. Coaching and beginner-friendly support help you choose discards based on your strategy and improve your understanding of Riichi Mahjong.

Statistics from your most recent 200 hands include win rate, deal-in rate, Riichi rate, call rate, tenpai rate at exhaustive draws, average winning score, and overall score balance. With Hand Replay, you can review your decisions one discard at a time and compare the tile you actually discarded with the recommended choice. Shanten count and improvement tiles are also shown to help you understand why another choice may be stronger. Records from shared games are available to participating players, so each player can review results from their own seat. NO PHYSICAL TABLE OR TILES REQUIRED You do not need an automatic mahjong table or a physical set of tiles. With a table and an iPhone, Jantaku AR creates a virtual mahjong table in AR. Players gather around the same real table and share the same virtual game. Move around the table and the view changes naturally, just like sitting around a real mahjong table.
