Sure! Here's an example implementation of a simple Block Breaker game using JavaScript and HTML:

To play this game on a smartphone, you can simply open the HTML file in your phone's browser. The game uses touch-based input for controlling the paddle. Slide your finger horizontally on the screen to move the paddle left and right. The objective of the game is to break all the blocks with the ball by bouncing it off the paddle. If the ball falls below the paddle, the game ends. If you manage to break all the blocks, a "Congratulations! You won!" message will be displayed.
