The Chinese Checkers AI I built for my mom

My mom loves Chinese Checkers. Growing up, our family would play together for hours. But when my brother and I left for college, my mom had no one to play against. She tried to find a good website or iPhone app, but none of the computer opponents were fun or strong enough.

The desire to build my mom a worthy opponent grew into JumpStar, the world's strongest open, verifiable Chinese Checkers AI engine for classic and multiplayer play, with results published in the public CCERL benchmark. My mom has been playing every day, and this project has rekindled our joy of the game. I hope you find it enriching too!
