AI将棋-オンライン対戦と最強AI is a free board game developed by Kiyofumi Nagami for Android devices. This game offers two main game modes: online play and playing against the strongest AI. The AI level ranges from beginner to professional, and during the game, the AI evaluates the situation. The game is designed to consume less battery power on your phone by processing the AI's thinking on external servers.

The online play is free, and you can play as many games as you want. Additionally, you can view your game records from your "My Page" and set your favorite avatar, ranging from historical figures to animals. However, it is important to note that the game is designed to end in 10 minutes, and the player who exceeds the time limit will lose.

Overall, AI将棋-オンライン対戦と最強AI is a great game for those who love to play shogi and want to play against AI at different levels or compete with other players online. It is also worth mentioning that the game was featured on Appliv.
