Sure! Here's an example of a simple game implemented as a single HTML file using JavaScript and script tags, designed for smartphone operation with the use of pictograms:
In this game, the player can choose between rock, paper, and scissors by tapping on the corresponding pictogram. The computer randomly selects its choice, and the game determines the result (win, lose, or tie) based on the classic rock-paper-scissors rules. The score is displayed at the top, and an alert message shows the player's choice, computer's choice, and the outcome of the game.
Note that you would need to replace the image file URLs (`emozi_all/rock.png`, `emozi_chicken.png`, `emozi_all/scissors.png`) in the code with the actual URLs or paths to your desired pictogram images in order for them to display correctly in the game.
