In most cases you can! Your first deposit bonus is designed to let you explore all nooks and crannies of the casino before you commit too much real money to it. This means that you can play live games with your deposit without any issue, just like you would any other game on the platform. While there are exceptions, you can certainly use your first deposit on all roulette games (live dealer roulette and table roulette alike), just as you would any other game with live dealers. Make sure to play responsibly and read the terms and conditions before you deposit!
