This scavenger hunt game is built using Twilio's MMS feature to send picture clues to players, who then text back a keyword that must be found at the location depicted in the picture. The game uses Sinatra as the web framework and DataMapper for database management. When a player texts back a correct keyword, they are given the next clue and their progress is tracked. If they miss a keyword, they receive another clue with instructions to try again. The game includes features such as verifying player identity through phone number and keeping track of completed clues. The master route handles incoming texts from players, verifies keywords, and updates the player's status accordingly. To connect the game to Twilio, the server endpoint is set up in the Twilio dashboard, allowing for seamless MMS sending and receiving. The game includes suggestions for customizing the experience and has a GitHub repository with example code and additional features.
