King

The King is functionally the same as the king in regular checkers. It can move and capture both forward and backwards, unlike non-kinged pieces. It costs 2 points.

Normal Kings Vs. Bought Kings
Like in normal checkers, when a non-king piece moves to the other end of the board (the opponent's backrow), it becomes a king. This counts for most pieces with special abilities, so you can have kinged King-Killers, kinged Two-Timers, etc. The only exception is when a King that was bought at the begining of the game reaches the opponent's backrow, nothing happens. There are no kinged Kings.

Basic Plays
Kings have more advanced positioning ability, as they can move and capture forward and backward on the board. Kings can easily capture Two-Timers by jumping over them and then jumping backwards over them again, returning to their original position.

Advanced Plays
Early in the game, you can make your opponent move their pieces into a bad position while you maintain your formations by using the King's mobility. Later on in the game, the King can act as a defensive piece to prevent enemy kinged pieces from surviving long.
