I've never owned one and have always been curious. What I'm asking must fluctuate according to activity at the time and all the rest but how much would you usually need in your vault to start out? I'm not even sure how many are into the gambling aspect, I'm just curious about what it's like owning one and the costs. 

I've owned one on more than one occasion. Users only broke the bank once and that was my fault. Usually 20m is enough.

It's 110-120 million I forget which. Thats a 100 for the purchase and the rest goes in the vault

You have some control over pay tables and how much you allow people to bet

You collect rakes from cash poker tables you can create in the casino interface

You collect losses and payout wins from your vault

If you bankrupt your vault you lose the casino, you get nothing in return

In the future this should go in the Help Forum. Good luck.

not worth it to buy tbh

no one really uses it, all gambling uses dice anyway

squishy should either move some of the dice stuff to being player run (with bankroll from the casinos) or scale down the pricing of the casinos and add in some new gamees

I may be imagining things but iirc Squishy has said in the past that it's a known money-sink.  Not really a thing to make you rich but more like a long-term goal for players that had too much money and didn't know what to do with it.

Doesn't seem to be doing bad over the last 30 days. Only 1Bn in cash and 3k+ of credits.  

Dice != casino...
