Bonuses in online casinos bring new players in and keep regular players interested. Usually they offer free credits for depositing money or referring a new user. Some will let people play for free and keep their winnings. Free participation in tournaments and keeping the prize is not usually counted as a bonus, but in reality it works like one.
One type of freeroll tournaments offers cash that can be used for betting in the casino or as entry free for other tournaments. You get to enter a beginner’s freeroll tournament that is open only to new members so that no one feels intimidated. All online casinos with tournaments have freerolls, often every day. The prizes are relatively small because they’re free. Usually you get 30 minutes to play. It’s good to use this time to your advantage – either for winning or for learning and developing strategies. VIP freerolls happen much more rarely, but the prizes are much bigger. They’re open to the loyal players who wager regularly and reach VIP levels.
In the other type of freerolls tournaments you can win free entries to otherwise paid tournaments with huge prizes. The players might need to go through several qualifiers if the tournament lasts a few months. Winning $10,000 or more and building up your bankroll is not impossible when you start from freerolls.
