How much for a child and a adult

To get in is free.....you have to pay for food.....and games.

Typically $20 for a 30 minute game card and $40 for 60 minutes. Also can load points onto a game card instead of time. Pizza is about $15 And they have a salad buffet now.

It's free

Do they still do coins instead of a card or both ?

Buy points rather than time if you have small kids

It's free to enter, and to participate in the arcade games you load money into a vending machine and use a card to play any games for a certain amount of time

You pay for what you want
