Sure, I can help you create a simple group game using JavaScript in a single HTML file. The game will be designed for smartphones and will use pictograms. Here's an example implementation:
Group Game
Instructions: Each player takes turns choosing a pictogram. The goal is to select pictograms that form a common theme. The player with the most matching pictograms wins!
In this game, players take turns selecting pictograms by tapping on them. The goal is to pick pictograms that have a common theme. Once each player has selected three pictograms, the game will display the theme and reset for the next round. Players can continue playing by selecting new sets of pictograms.
Feel free to customize the pictograms array with your own set of pictograms suitable for 1st to 5th-grade players.
