Help a friend: did you buy the game currency in the video game? What should I do if I can't play the game currency because the slot size of the machine is different? How can I enlarge the slot?

Not everything. There are big and small. I used to work in a city where video games were played.

All video game cities adjust all holes according to their own game currency size. If you throw them in, they will get stuck in the hole, and the small ones will fall directly. Only coins of the same size can be adjusted in the slot of the machine.
