9マス将棋VS - 小さなマスで詰将棋 - is a shogi game built around a nine-square board instead of the usual 81-square layout. The central objective is to outsmart an opponent in a smaller contest, with options to play against the computer or challenge a friend nearby.
A smaller shogi board
The reduced board is the defining change from traditional shogi described for the game. With only nine squares in play, the match takes place in a compact space, while the aim remains to think strategically and beat the opposing player. The source does not specify changes to shogi piece movement or other rules, so the board size is the documented distinction.
Computer and friend matches
For solo play, the computer opponent is offered at various difficulty levels. This gives players a choice of challenge, with the game described as suitable for both beginners and advanced players. The other stated option is a match with a nearby friend, where each player tries to outthink the other. No online multiplayer mode is specified.
Practice and review
Players can start by practicing alone to become familiar with the game mechanics, then try different strategies and tactics. The source also recommends thinking back over moves after a game and considering how to improve. These suggestions frame play around learning from each match, whether the opponent is the computer or a friend. No additional campaign, unlock system, or progression structure is described.
