I know that some of the arcade games like the coin pushers you actually get more credits of you insert cash. I didn't realize that until I had used on the money i loaded on the card
Prices of games vary. Usually .25-.50 per play. You use a card they give you to add money on and then swipe at each game to play. Putt putt is about $7 per person.
When we go just for arcade games I usually give my daughter about $20 to $25 to play with. It lasts long enough and usually has gotten enough points for a decent prize stash.
