Offline relaxing games for cruise

Hello! I won’t pay the exorbitant rate for cruise ship WiFi, and I’m also not much of a gamer.

However, since during downtime or lying in bed at night I won’t have access to my typical mind-numbing scrollable apps, I’d like some games that can be used entirely offline.

Puzzle games: sudoku, logic puzzles, maybe some easy number games…anything low key and relaxing.

Happy to pay a buck or two if the games are actually good and will definitely work in airplane mode, without needing to access WiFi for ads and junk.

Thank you!!! ❤️
