So, Rush in computer and video games means that you have to complete a task or goal really quickly. It's like when your mom tells you to clean your room before dinner, and you only have a little bit of time to get it done. In a game, you might have to get to a certain point on the map, or collect as many coins as you can before time runs out. Basically, you have to move fast and think fast to get the job done in time. It's like a race against the clock!
