# Game settings

Game settings change the way the game is initialized. `Player count` is a setting that all games have. Two player games such as *Tic-Tac-Toe* always have two players, while some multiple player games like *Uno* supports between two to four players. 

Some games have additional game settings. In *Dots and Boxes*, there is a `Size` setting that takes on the values `2x2`, `3x3`, `7x7`, and `Any`. Bots do not have access to the game settings field because they can be implicitly derived from the game state. In this *Dots and Boxes* example, the game setting gets converted into the `board_width` and the `board_height` fields. 

```protobuf
message State {
  // Required field to indicate the player who should be making the next move
  // Values = 0 or 1
  int32 player_turn_idx = 1;

  // The array is stored in row major order, so index 0 is the top left and 
  // last index is the bottom right. In a size 2x2 board, index 1 is the 
  // top right board. 
  repeated Box board = 2;

  // Number of horizontal boxes in the grid
  int32 board_width = 3;

  // Number of vertical boxes in the grid
  int32 board_height = 4;
}
