Common in wallets, less common in casino cashiers.
Wallet support outruns cashier support
Polygon is well established in wallets and in decentralised applications, and tether moves on it cheaply and quickly. Casino cashiers have largely not followed, and it is the least frequently listed of the routes covered here.
So the usual situation is a reader holding Polygon USDT at a casino that does not take it. The answer is to convert inside an exchange rather than to look for a bridge, because bridges add a step with its own fees and its own ways to go wrong.

It uses Ethereum's address format
Which means the same trap as BEP-20: a Polygon address is a valid-looking Ethereum address, a wallet will let you send to it, and the transfer will land somewhere nobody is watching.
Three networks, one address shape, no error message. The network label on the cashier screen is the only field that distinguishes them, and reading it is the whole of the defence.
When it is genuinely the right route
When the cashier lists it and your balance is already there. That is the entire list, and it is not a criticism of the network — it is a statement about where casino integrations currently are.
The decision page works through what to do when your balance and the cashier disagree.
Operators that publish this route
Taken from what each operator publishes, not from what a homepage badge implies. An empty column means this site has not recorded that operator's network list — it is a gap here, not a statement that the operator has none. The deposit screen settles it.
Every button opens the same casino, which is why none of them carries an operator's name.
