Paschilos are Japanese, they use "Metals" which is the Japanese translation of token.
Pachinko uses metal balls (also metals).
You can have games of Chance in Japan but they cannot have a reward that is more than 3x the bet.
So with a Paschilo if you put in 5 coins the max win is 15 coins.
The way they get around this is a "fever" round where if you hit this, they pay 15 coins, then automatically take 5 coins with a guaranteed win and cycle through that as many as 30 times. Paying out 300 metals (as your actually winning 10 coins per).
As an Arcade for entertainment purposes only (nudge nudge wink wink) - Metals cannot be converted back to cash - so you go to the redemption counter and get your giant stuffed bear (blender, toaster, etc) - which is in a large plastic bag with a bar coded security tag on it. When you leave the "arcade" you will find another close by store - called the prize redemption center. Which is theoretically unrelated to the "arcade" - and surprise .... they are interested in purchasing your giant stuffed bear for cash. This is provided you have not in anyway opened the bag or removed the security tag. If you were to buy 10 metals for 100yen (roughly $1 usd), and you somehow turn these into a 1000yen, which gets you a stuffed bear, the prize redemption center would give you something like 600Yen for your prize. Of course their are all sorts of player clubs where if you had gold status you might get 700yen for your status rather than 600. There are restaurants in the arcade that you purchase your ramen by using Metals. Same bowl of soup is 700Yen or 1100metals.
