Sure, here's a simple game called "Mario Addition: Spikes Cave" implemented as a single HTML file using JavaScript. The game will run on smartphones and uses pictograms for visual elements. Please note that this is a simplified example and may not have extensive gameplay or graphics. Copy the code below into an HTML file and open it in a web browser to play the game.

In this game, you'll control Mario by tapping/clicking on the screen. Mario will jump up when you touch/click and there will be spikes moving from right to left trying to hit Mario. The objective is to avoid the spikes and survive as long as possible. If Mario collides with a spike, the game will end and an alert will be shown.
