SAND is the token of The Sandbox, a virtual-world platform, and at the casinos that accept it, it moves as a single ERC20 asset — there is no alternative network here, so deposits and withdrawals carry Ethereum mainnet's standard gas costs regardless of which casino you use.
Support for SAND is narrower than for the majors on this list. Where it is accepted, it is worth confirming the casino's specific minimum deposit and withdrawal figures rather than assuming they mirror a more widely supported coin on the same platform, since smaller-token liquidity and processing can differ meaningfully between operators.
Like most non-stablecoin tokens here, SAND's price is driven by the broader market rather than pegged to anything, so a balance held in it between a deposit and a later withdrawal is exposed to real price movement independent of anything happening at the casino.
