Play Checkers against the computer.
Player one is GREEN and player two is BLUE. By default you are player one and the computer is player two, but that can be swapped when starting a new game. The board is always drawn with your pieces at the bottom.
When you hover over a piece that can be moved it is highlighted in YELLOW. Click on a highlighted piece and the squares it can move to will be outlined in YELLOW. Click on one of the outlined squares to make the move, or click on a different piece to see what moves it can make. After an initial jump, if another jump is possible, the squares you can jump to next are outlined in YELLOW.
After you move, the computer will "think" and then make its move. The computer's move will be highligted with a dashed BLACK outline.
The computer uses JSMCTS, a javascript implementation of Monte Carlo Tree Search (MCTS) that runs in the browser, to select a move. It displays the moves it is evaluating and what percentage of the time those moves lead to a win. The number of trials it runs and the amount of time it has to run them can be controlled.
