Take your mahjong table anywhere. Jantaku AR turns a real table into a shared Riichi 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 share it from their own seats. You can also practice alone in 3D mode, with no AR marker. A discard coach helps you choose what to throw, and a built-in guide teaches scoring and yaku as you play. MAIN FEATURES Shared AR table for up to four players • A 3D table appears on the real table in front of you • Up to four iPhones share one table over the local network • Each player sees their own hand from their own seat Single-player 3D mode • No AR marker and no camera required • Play against AI opponents on one iPhone • A discard coach matched to your play style, free daily hand included • The coach explains why it pushes or folds, point by point One to four human players • AI players in five styles, retuned over thousands of simulated games, fill any empty seats • Japanese competition and standard rule presets • International competition rules too (30,000-point start, no red fives, no abortive draws) The game runs itself • Dealing, draws, discards, calls, wins and scoring are handled • Riichi, Chi, Pon, Kan, Ron and Tsumo; choose whether to call with a red five • A digital score display for all four players Every win, explained • The winning hand in tiles, with the winning tile outlined • Each yaku with its fan, and the total • Minipoints set by set, with rounding and how the points follow • Everyone's score and placement after the hand Scoring guide Open it from Settings or from any win: • A scoring table that follows your rules, rounded-up mangan included • How minipoints are counted, with a worked example • Every yaku with its fan closed and open, and an example hand in tiles RESULTS AND GAME REVIEW Every hand is recorded, and your most recent 200 hands are summarized: • Win, deal-in, riichi and call rates • Tenpai rate at draws, average win and balance • How often your discard matched the best one • Your 1st-4th finish rates and average placement • A written assessment of your play Charts show how you are changing: • Placement over your last 50 games, with a 10-game moving average • Placement distribution, last 50 games or all time • Attack vs defense: win rate against deal-in rate, all time and recent Hand Replay steps through your discards beside the recommended tile and its shanten count. Winning hands end on the same win screen as in play. Records reach every player, so each can review the game from their own seat. WHY JANTAKU AR No automatic table, no physical set: any table and an iPhone are enough. Not online mahjong: you meet in the same room, around the same surface. And a real table keeps no record, so face-to-face players could never tell whether they were improving. Jantaku AR is the table, so every hand is kept. TRY IT FREE One hand per day is free, so you can try AR, local play and 3D mode on your own devices first.
