 # Game
 
-Most generally game is a form of play which is restricted by certain rules, the goal of which is typically [fun](fun.md), challenge and/or [competition](competition.md). A game may have various combinations of mathematical/mental elements (e.g. competitive mental calculations, mathematically defined rules, ...), physical elements (based in [real life](irl.md) physics, e.g. [football](football.md), [marble racing](marble_racing.md), ...) and even other types of elements (e.g. social, psychological, ...); nowadays very popular games are [computer](computer.md) games, or video games (also gaymes or vidya, e.g. [Anarch](anarch.md), [minesweeper](minesweeper.md), [Doom](doom.md), ...), which are played with the help of a computer. An entity (human, computer, animal, ...) playing a game is called a player and his ability to play it well is called [skill](skill.md). *Game* is also a [mathematical](math.md) term in [game theory](game_theory.md) which studies games and competition rigorously.

 It's quite hard to exactly define what a game is, it is a [fuzzy](fuzzy.md) concept, and it is also hard to categorize games. Let us now define a simple classification of games by their basic nature, which will hopefully be suitable for us here:
 
-- **[mathematical](math.md) games**: Games taking place in an abstract mathematical space, with exactly defined rules. Though mathematical games may of course be represented in real life (e.g. by physical chess pieces made of wood), such a representation is only a helper for the player and doesn't rule the game out of this category.
+- **[mathematical](math.md) games**: Games taking place in an abstract mathematical space, with exactly defined rules. Though mathematical games may of course be represented in real life (e.g. by physical chess pieces made of wood), such a representation is only a helper for the player and doesn't rule the game out of this category. Mathematicians try to *solve* these games in various ways, e.g. by trying to construct an [algorithm](algorithm.md) for perfect play or proving that with perfect play one of the players can always secure a win.
   - **[computer](computer.md) games**: Mathematical games that practically REQUIRE a computer (and usually have been design as such) to be played due to the computations involved being very numerous and/or complex -- for example [Doom](doom.md).
   - **non-computer mathematical games**: Mathematical games that do not require a computer (though of course their computer implementations may exist) as the calculations involved can be practically performed without it -- for example [chess](chess.md).
 - **[real life](irl.md) games**: Games taking place in real life, i.e. usually making use of real world physics or other laws (e.g. social ones) -- for example [football](football.md) or [marble racing](marble_racing.md).
