The game is most likely Caylus , the board game. It’s a worker-placement strategy game, and the name matches the clue closely from the public results I found.

Why this fits

  • Caylus is an established game title, not just a person’s name.
  • It’s described as a classic worker-placement game about building and expanding a town.
  • The wording in your question seems to be a misspelling or shorthand around “Caylus,” which is the clearest match from the available information.

Quick note

If you meant a video where Caylus played something with “Casio” in the title, that title wasn’t clear from the results I could verify here.
