Click and drag your pieces. The system will instantly calculate the mathematically perfect countermove. Why Chinook Matters to Modern Gaming and AI
Chinook wins the right to play for the world championship but faces political hurdles in the checkers federation.
The simplest way to experience the unbeatable AI without dealing with complex installations is to use the official University of Alberta web portal. This method is highly recommended for players who just want to test their skills against the champion.

Chinook uses a combination of alpha-beta search, a massive opening book, and an endgame database. For software developers and AI researchers, studying Chinook’s algorithms is a masterclass in game theory.
: Serious players and developers can download the actual "brain" of the program. The Endgame Databases include perfect information for all positions with 8 or fewer pieces, totaling over 2.7 GB of data. Click and drag your pieces
The first version of Chinook was developed in 1986 by Jonathan Schaeffer, a computer science professor at the University of Alberta, Canada. Initially, the program was designed to play American checkers, but it was later adapted to play other variants of the game, including English draughts. Chinook's early success was largely due to its innovative use of AI techniques, such as alpha-beta pruning and transposition tables.
In 2007, the Chinook team announced that checkers had been "solved." With perfect play, the game always ends in a draw. Chinook’s internal database contains every possible move of the game—over 500 billion positions. When you download and run the official Chinook engine, you are playing against an entity that literally cannot make a mistake. No human, and no other software, can consistently beat the full-powered version.

The software’s dominance is built on three main pillars of computer science:
The software combined a deep search algorithm with a massive endgame database. This database contained every possible position with 10 or fewer pieces on the board. When the program reached these endgames, it no longer had to calculate moves—it already knew the mathematically perfect path to victory.
Today, Chinook remains a for:
