Pictogram Guessing Game
Guess the correct pictogram based on the hint.
In this game, the player is presented with three pictograms and a hint. They need to select the correct pictogram based on the given hint. Once they tap on a pictogram, the JavaScript code checks if their selection matches the correct answer. If it does, a congratulatory message is displayed; otherwise, an error message suggests trying again.
