Seishin Gakuen Shogi Club (清正学園将棋部) is a single-player Shogi (Japanese chess) game. Everything runs on the device; the app never goes online.

Features

* Complete Shogi rules — check, nifu (double pawn), uchifuzume (pawn-drop mate), sennichite (repetition, including the perpetual-check loss) and nyuugyoku (entering-king, 27-point rule).
* Offline AI — an AlphaZero-style policy + value network (Bonanza-method trained) runs on-device through a single-threaded PUCT MCTS. Eight strength levels.
* Eight opponents — club members and teachers from Lv 1 to Lv 8, each with a portrait and a short bio.
* Teacher mode — tap "Ask Kato-sensei!" during a game to see the top three candidate moves with win rates. You still choose the move yourself.
* Play experience — multi-step undo, resign, last-move highlight, piece and UI sounds, haptics, save and resume.
* Kifu save and review — 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.
* Board — kaya-style wood grain, traditional pentagonal pieces, brush-script piece kanji (Fude Goshirae).

The user interface is in Japanese.
