Pictogram Game
Tap on the correct pictogram!
In this game, you need to tap on the correct pictogram to increase your score. The available pictogram images are defined in the `pictograms` array. Each time you tap on the correct pictogram, your score increases and a random new pictogram is generated. The game is over when your score reaches 10, and then you have the option to reset the game by tapping on any pictogram.
