Sure, here's a simple game that meets your requirements. The game will be displayed as a 10x10 grid of pictograms, and the player's goal is to find the blue square.
To test the game, simply copy and paste the entire code into a blank HTML file (e.g., "game.html") and open it in a web browser on your smartphone. The game will generate a 10x10 grid of cells, one of which will be randomly chosen to be blue. When you tap/click on a cell, the game will check if it's the blue cell. If you find the blue cell, you'll be congratulated, but then alerted that you died afterwards.
