Google Forms are excellent for creating escape rooms.
Use short answers (instead of multiple choice) along with Validation to have students respond to clues. In the clue itself, be sure to add if you require all caps or lower case or a number.
If they answer it incorrectly, give them another clue under Custom error text.
If they answer correctly, add a section for another clue or for the final slide.
Escape rooms can also be called Digital Breakouts, when looking for examples.
