Sure! Here's a simple text-based futuristic tycoon game implemented as a single HTML file using JavaScript. Since it's a text-based game, I won't be using pictograms, but you can play it directly in your smartphone browser.
When you open this HTML file in your smartphone browser, you'll see a simple game interface. The goal is to buy robots and sell them to make a profit. You start with $100 and each robot costs $20 to buy and sells for $10. The game keeps track of your money and the number of robots you own.
You can tap the "Buy Robot" button to buy a robot if you have enough money, and tap the "Sell Robot" button to sell a robot if you already own one. The game will update the statistics (money and robots) after each action.
That's it! You can try running this game on your smartphone and start building your futuristic robot empire.
