モバイル将棋 is a free board game available for Android devices. While the AI may not be very strong, it offers the option to play with handicap settings and compete to find the shortest checkmate solution, making it enjoyable for advanced players as well.

With regular updates, the game also introduces various initial board configurations and slightly different rules from traditional shogi, providing the opportunity to explore different checkmate patterns on each board.

In addition to the standard game mode, which includes both regular and handicap matches, モバイル将棋 offers several other modes for players to enjoy. These include:

• Fuhyo Shogi: A variant where players only have pawns, gold, and the king in their starting positions.
• Naked Shogi: Three different variations where players start with only the king and the rest of the pieces are held in hand.
• Anaguma Shogi: A variant where the AI plays as the strongest defensive formation, known as "Anaguma."
• Tokin Shogi: A variant where all the AI's pawns are replaced with gold generals.
• Complete Shogi: A chess-like variant where capturing all the opponent's pieces is required for victory.
• Bonus: A puzzle-like mode similar to tsume-shogi.

It's important to note that the regular game mode may not be suitable for advanced players. However, if you're looking for challenges like solving checkmate puzzles or playing with slightly different rules, モバイル将棋 can still provide an enjoyable experience.

The game received updates in December 2021, adding the Fuhyo Shogi mode and Bonus 3. In November 2017, various shogi features were incorporated, including the AI's handicap settings and the addition of Naked Shogi 3 to the game.
