Checkers

## Introduction

A timeless classic offering complex strategy with simple rules.

Checkers is a game with traditions streching back thousands of years, and is played today in many parts of the world. Most often played on a 8×8 chessboard, but it can also be played on larger and smaller boards. A common classic version is played on a 10x10 board, which you can create with the Green Box.

## Setup

To create a 10x10 board, simply build a 5x5 grid using the back/yellow side of the tiles. Each tile is divided into 2x2 small squares. Players select a colour, and place their cubes in starting positions on opposite sides of the board.
Start by placing a cube in the bottom right corner. Then place a cube on every other square on the row. In the second row place cubes diagonally adjacent to the cubes in the first row and continue this pattern for four rows. When you’re done you should have 20 cubes forming a diagonal pattern across the first four rows, and using the same diagonal lines across the board as your opponent.

## Play

Here are the basic rules, courtesy of Wikipedia:

### General rules

Draughts (or checkers) is played by two opponents, on opposite sides of the gameboard. One player has the dark pieces; the other has the light pieces. Players alternate turns. A player may not move an opponent’s piece. A move consists of moving a piece diagonally to an adjacent unoccupied square. If the adjacent square contains an opponent’s piece, and the square immediately beyond it is vacant, the piece may be captured (and removed from the game) by jumping over it.

Only the dark squares of the checkered board are used. A piece may move only diagonally into an unoccupied square. Capturing is mandatory in most official rules, although some rule variations make capturing optional when presented.[citation needed] In almost all variants, the player without pieces remaining, or who cannot move due to being blocked, loses the game.

### Men

Uncrowned pieces (men) move one step diagonally forward, and capture an opponent’s piece by moving two consecutive steps in the same line, jumping over the piece on the first step. Multiple opposing pieces may be captured in a single turn provided this is done by successive jumps made by a single piece; the jumps do not need to be in the same line but may “zigzag” (change diagonal direction). In English draughts men can capture only forward, but in international draughts and Russian draughts they may also capture (diagonally) backwards.

### Kings

When a man reaches the crownhead or kings row (the farthest row forward), it becomes a king, and is marked by placing an additional piece on top of the first man, and acquires additional powers including the ability to move backwards (and capture backwards, in variants in which they cannot already do so). As with non-king men, a king may make successive jumps in a single turn provided that each jump captures an opponent man or king.

In international draughts, kings (sometimes called flying kings) move any distance along unblocked diagonals, and may capture an opposing man any distance away by jumping to any of the unoccupied squares immediately beyond it. Since captured pieces remain on the board until the turn is complete, it is possible to reach a position in a multi-capture move where the flying king is blocked from capturing further by a piece already captured.

Flying kings are not used in English draughts, in which a king’s only advantage over a man is the ability to move and capture backwards as well as forwards.

## Winner

Once a game has been gridlocked, where only back and forth moves between same locations on the board avoid jumps, the player with the majority of free space wins the games.
