Everything runs on the device; the app never goes online.\n\n<b>Features</b>\n\n* <b>Complete Shogi rules</b> — check, nifu (double pawn), uchifuzume (pawn-drop mate), sennichite (repetition, including the perpetual-check loss) and nyuugyoku (entering-king, 27-point rule).\n* <b>Offline AI</b> — an AlphaZero-style policy + value network (Bonanza-method trained) runs on-device through a single-threaded PUCT MCTS. Eight strength levels.\n* <b>Eight opponents</b> — club members and teachers from Lv 1 to Lv 8, each with a portrait and a short bio.\n* <b>Teacher mode</b> — tap \"Ask Kato-sensei!\" during a game to see the top three candidate moves with win rates. You still choose the move yourself.\n* <b>Play experience</b> — multi-step undo, resign, last-move highlight, piece and UI sounds, haptics, save and resume.\n* <b>Kifu save and review</b> — export games as .kif, then replay and analyse them from the title screen. Every move is evaluated by MCTS and tagged ◎ good / △ dubious / × blunder, with a recommended move for blunders.\n* <b>Board</b> — kaya-style wood grain, traditional pentagonal pieces, brush-script piece kanji (Fude Goshirae).\n\nThe user interface is in Japanese.\n\n<b>Privacy</b>\n\nNo network permission. No ads, tracking or analytics. The AI model runs locally.\n\n<b>License</b>\n\nGPL-3.0-or-later. Source code:\nhttps://github.com/hiroshiyui/SeiShinGakuen_ShougiBu\n","categories":["Board Game"]}
