GAME

Even if a game is "a thing competing for victory or defeat", a fighting partner may not be another person. A lot of games that I can enjoy alone are known.

The game that I can enjoy alone is called a sled tail (a solitaire) or patience. As for many of sled tails, some kind of aims are decided beforehand and "beat" it in the case that was able to arrive at this aim and think about the case that is not so with "a defeat".

The thing of various kinds is known from the things which I used a thing, the card that I used a board for a sled tail for old days. A lot of things which assumed that many of recent TV games are idle alone the principal objective can classify all these in a sled tail.

For a normal game except the sled tail, there are a thing (a game of go, shogi, a contract bridge) and a thing (I arrange poker, 7, Old Maid) which is not so which the number of people to participate in a game fixes. A thing (2 people - 5 people) of to have the upper bottom is common even if I do not fix it.

In addition, there is the thing (five hundred, pinochle) which a rule turns into by the participation number of people.

In addition, I am different and suppose the intention of other players in the case of the multiplayer game that there are plural players by the one game (one-person games) with the partner (for example, obstacles such as nature) who does not have intention, and it is it with a game without the element which I pressure it to work on to change the intention.

As for game of go, shogi, Othello, information covered with a meaning to understand all the hands of the current partner is the game that there is not; (a complete information game).

In contrast, it may be said that poker, mah-jong are games to increase the element to suppose information covered by the hands of the partner player (an incomplete information game).

The difficulty of issue of victory method search itself of the game is not defined for the moment, and the difficulty of the victory method search problem for the class of the game is defined.
