\*In the first part of our series on building an on-chain game on StarkNet, we set up and built a simple on-chain game called Stark Racing using the open-source HTML5 game development framework Phaser. The game allows users to connect their StarkNet wallet directly on Phaser, mint a car with a random speed property, and race against another car. The fastest car will win the race and be rewarded with a token called $SPEED. \*
