Chess is more than just a game. This is an intellectual pastime, a way to develop logical thinking and visual memory. Chess has deep roots in history, which means it has stood the test of time and is one of the oldest strategy games in the world.

The ultimate goal of the game is to checkmate your opponent. This means that the opponent's king finds himself in a situation in which capture is inevitable.

Shapes:
1. Pawns - move one square forward or 2 squares if this is the first move.
2. Knight - moves two squares vertically and one horizontally or one square vertically and two horizontally.
3. Bishop - moves diagonally to any number of squares.
4. Rook - moves one or more squares vertically or horizontally.
5. Queen - moves any distance horizontally, vertically or diagonally.
6. King - moves one square in any direction.

Rules of the game:
The rules correspond to the classical rules of chess. All chess pieces are standard and follow international rules. Select the difficulty level, first easier and then more difficult, try playing at all difficulty levels. You can also play with a friend or family member by selecting the two-player game mode, i.e. against each other and take turns. In the game, you can customize the design style of the chessboard and table, and turn sound effects on or off. There is also the ability to manually and automatically save the game.

1. Checkmate - when the player's king is in check and there is no way to get out of it.
2. Pat - The game ends in a draw if the player has nowhere to move, but there is no “check”.
3. Draw - there are not enough pieces to checkmate:
- King against king and bishop;
- King against king and knight;
- King and bishop against king and bishop (and bishops are on squares of the same color).

Castling is performed by the king and rook and can only be played after the pieces between them have been removed. The king is placed first two squares to the right or left, and then the rook from this corner “jumps” to the square that the king crossed.

Castling is not allowed when:
- The King or Rook has already moved;
- The king is in check;
- The king will go through check.
