To play the game, you need to serve customers the correct type of sushi by adding toppings to a plate of rice and placing it on the conveyor belt. Each customer wants a specific type of sushi, but they won't tell you exactly what they want. You'll need to watch for clues from the customers as the sushi goes past them. To add a topping to the rice, click on it with your mouse. Then, click on the plate to add it to the conveyor belt. Every time you add a plate to the belt, it costs money. However, you'll earn much more money after a customer is served. If you need to speed up the game, you can press the fast forward button to speed up the conveyor belt. Your goal is to reach your cash target before running out of time, so watch for clues and serve the right sushi to each customer to earn as much money as possible.
