CRO is the native token of the Cronos chain, an ecosystem built by Crypto.com, and at the casinos on this list it moves as an ERC20 token, carrying Ethereum's standard gas costs on deposit and withdrawal since no alternative network is offered here.
It is a narrower-support coin than Bitcoin, Ethereum or the major stablecoins — fewer crypto casinos list it, and where they do, liquidity and withdrawal processing tend to be less thoroughly tested by volume than for the coins everyone accepts. That is not a red flag on its own, just a reason to check a given operator's specific minimums and any withdrawal notes for CRO rather than assuming it behaves identically to more established options on the same site.
CRO's price, like most non-stablecoin tokens on this list, is meaningfully more volatile than Bitcoin's, so a balance held in it between a deposit and a later withdrawal carries real exposure to price movement independent of anything happening at the casino itself.

This list holds fewer than 5 casinos, so it is kept out of search results until it offers a real choice.
