Sure! Here's a simple implementation of Tetris game using JavaScript, HTML, and CSS. The game is optimized for smartphone operation and uses pictograms for a better visual experience. Please note that due to the limitations of the text-based format, I won't be able to provide interactive gameplay, but you can copy and paste the code into a single HTML file to play it yourself.
Please note that the code provided is just a starting point for implementing Tetris and lacks the actual game logic such as handling user input and updating the game state. You would need to add additional JavaScript code to handle these aspects to create a fully functional game.
