Sure, here is an example of a Frog Leap game implemented in a single HTML file using JavaScript:
Frog Leap Game
This code creates a Frog Leap game where there are three green frogs and three brown frogs placed on a game board. The objective of the game is to move all the green frogs to the right side and all the brown frogs to the left side.
You can play the game by clicking on a frog, which will cause it to leap over its adjacent frog (if there's an empty spot available) or perform a reverse leap. The game will determine if the move is valid, and if all the frogs are correctly positioned, it will display a winning message and offer an option to reset the game.
Note: To run this game, save the code into an HTML file and open it in a web browser.
