Sure! Here's an implementation of "The Pyramid Battle" game using JavaScript in a single HTML file. Since it's a smartphone game, I'll use pictograms for the characters.
In the game, we have a pyramid structure where characters battle against each other. At the bottom of the pyramid, we have Zebra, Cow, and Giraffe. In the middle, we have Fox and Hyena, and on top of the pyramid, the ultimate battle is against the Lion.
The power of each character is represented by a numerical value. The function `determineWinner()` compares the combined power of Zebra, Cow, and Giraffe against the combined power of Fox and Hyena. Based on the result, it determines who will defeat the Lion.
When you run this HTML file, it will display an alert with the winner of the battle.
