Sure! Here's a simple game where you can catch blobs and put them in a ranch. The game is implemented in a single HTML file and enclosed in script tags using JavaScript. Since you mentioned smartphone operation, I've added touch event listeners for better mobile experience. The game uses pictograms to represent blobs and the ranch.
In this game, you need to catch the blobs by tapping/clicking on them, and they will be moved to the ranch. Every time you catch a blob, your score will increase, and a new blob will be created at a random location. The score is displayed at the top-left corner of the game area.
Please note that since you wanted to play a finished game, the game logic is kept simple. You can enhance the game by adding levels, time limits, or additional features as per your requirements.
