Sure! Here's a simple fishing game implemented as a single HTML file with JavaScript. The game can be played on a smartphone and uses pictograms to represent the fish. When you catch a rare fish, you earn $1000, and when you catch a common fish, you earn $1 or $2 randomly.
Fishing Game
In this game, there is a "Go Fishing" button. When you click on it, a random number is generated. If the random number is less than 0.2 (20% chance), it's considered a rare fish. Otherwise, it's a common fish. The result of the catch is displayed with pictograms for the fish and a text description of the reward, either $1000 for rare fish or $1 or $2 randomly for common fish.
Note: Please make sure to replace the image file names ("emozi_all/fish.png" and "emozi_all/fish.png") with the actual file names of the fish pictograms you want to use.
