Sure! Here's a simple implementation of a block breaker game using HTML, JavaScript, and pictograms.

To play the game, simply save the code above as a `.html` file and open it in a web browser. The game can be played on a smartphone by touching and dragging the paddle to control its movement. The objective is to bounce the ball off the paddle and break all the bricks on the screen.
