Koop Checkers Kingdom - SteamCheckers Kingdom - Steam

FROM YOUR GRANDMOTHER'S KITCHEN TABLE TO THE PHANTOM'S THRONE

Learn the openings the masters actually play. Master the endgames every club player should know. Face opponents who play like real humans, not algorithms. Across every official ruleset, from your first move as a kid to tournament-level play.

This is checkers built like the masters built it.

EVERY OFFICIAL RULESET

Not a reskin. Not a single-rule port. The actual rules, properly implemented.
American Checkers. 8×8, men move forward, mandatory capture. The classic.
International Draughts. 10×10, flying kings, max-capture required. The global competitive standard.
Russian Draughts. 8×8, flying kings, mid-jump promotion. Men that reach the king row during a capture continue as kings.
Brazilian Draughts. International depth on the familiar 8×8 board.

LEARN THE GAME PROPERLY

An interactive Training Academy with lessons across basics, tactics, openings, middlegame, and endgames. Every lesson ends in a puzzle.
The Named Openings Trainer teaches real checkers theory: Single Corner, Double Corner, Bristol, Cross, Old Fourteenth, Dyke, and others from the classical repertoire.
The Endgame Trainer walks you through First Position, The Bridge, Payne's Draw, the Triangle of Petrov, and the other endings that actually win club games.
Post-game analysis tags every move (Brilliant, Best, Good, Inaccuracy, Mistake, Blunder) and scores your accuracy, the way serious players actually review.
Hints that teach why, not just what. Tap the hint button and you get the engine's best move plus a one-line explanation of the idea behind it.

OPPONENTS WHO FEEL HUMAN

A full roster of named AI opponents, from first-time newcomers to the Phantom himself. Each one plays with a consistent style, their own voice, and their own reactions to your moves. The difficulty you pick is the difficulty you get. No algorithmic difficulty spikes. No "the AI suddenly plays perfectly when you're winning."

A STORY OF YOUR OWN

A campaign that takes you from a worn wooden set on your grandmother's table, through village clubs and regional tournaments, onto the international stage, and finally to the Phantom's throne. Every chapter has its own cast. Every chapter ends on a boss with their own monologue.

FOR PLAYERS WHO WANT MORE THAN ONE BOARD AND ONE OPPONENT

Most checkers games give you one ruleset and a generic AI. This one gives you every official ruleset, a full roster of opponents who feel human, and the learning tools to master all of them. Whether you're revisiting a childhood game or climbing toward international competition, there's a ladder here for you.
