Sure! Here's a simple implementation of the Ouija board game using HTML and JavaScript, which can be played on a smartphone. It uses pictograms and allows you to "ask" questions and receive "answers" from a ghost.
The Ouija Board
To play the game, save the above code in a file with an `.html` extension (e.g., `ouija.html`). Open the file in a web browser on your smartphone. You will see a virtual Ouija board with a question input field, a keyboard, and a message area. To ask a question, tap on the letter buttons on the keyboard to spell out your question. Once ready, tap on the "Ask" button to see the ghost's answer in the message area. You can clear the question field and try again by tapping the "Clear" button. Have fun!
