Sure! Here's a simple tablet game implemented as a single HTML file using JavaScript. The game is called "PictoMatch" and the objective is to match pairs of pictograms within a given time limit.
PictoMatch
Time: 100s
Score: 0
Please note that you need to replace the `emozi_dog.png` with the actual paths to the pictogram images you want to use in the game. Also, you can add more pictograms to the `pictograms` array to increase the difficulty of the game.
