3 handpicked Scratch ai | Scratch projects

Some moves you think are bugs might actually be based on the rules. Make sure you understand specific moves like the king and rook’s, and the pawn’s “en passant” rule. If you want to see how the game evaluates moves, check out the black and white bar on the right side of the board. If the game seems too easy, try the “Difficult” level on TurboWarp. And if you manage to win, screenshot it for analysis; it’ll help you improve. There are various difficulty levels, from Easy 1 to Difficult (competition mode). Especially on TurboWarp, where the AI anticipates about 4 moves ahead at Medium or Difficult levels, giving a real challenge. If you’re remixing, do it before playing to keep the list from getting too long. Let’s all challenge the AI!

Summary of the author’s notes

overall board score, the number of moves available on a player’s turn, and the number of secure edge pieces leading to corners. This AI is strong in one-on-one attacks but weak in broader strategies. Interestingly, it performs slightly better as the second player. The method for calculating board value comes from Koso Sato’s work on evaluation functions.
