What Is a Pennsylvania Casino No-Deposit Bonus? Instead, use free bonus funds to check out the casino’s website and app. With these bonuses, you don’t need to deposit any money into your online casino account to try games, including slots, table games, and video poker. One of the biggest reasons to play at online casinos in Pennsylvania versus land-based ones is a special welcome bonus offered to new players, called a no-deposit bonus. Pennsylvania online casinos are rapidly gaining in popularity now that online gambling is legal in the state.
