Also known as sign-up bonuses, the new customer bonuses are a popular feature in almost all online casinos. While there is no rule as to how much a casino can give as a welcome bonus, most players are awarded a match bonus where the bonus is calculated as a percentage of the amount deposited.Welcome bonuses are classified into two broad categories; cashable sign-up bonuses which can be redeemed for cash and non-cashable sign-up bonuses which are used to play but cannot be converted to cash. In an effort to stay away from the competition, casinos review their bonuses all the time. For players to benefit from bonuses, they need to carefully choose where to play.Look out for casinos that give bonuses but also make provisions for players to win other types of rewards as they play. These types of casinos not only save players the initial deposit money but provide avenues to earn more than the game offers as a payout.If you are new to gambling, you need to first get familiar with a game before betting on it. If you choose a slot, choose one from a reputable provider like NetEnt or Microgaming. The best casinos allow players to win actual money before they deposit any of their own funds. While there are usually requirements to be met before withdrawing such winnings, the fact is that players do not spend until after they have won something. This gives new players an opportunity to decide whether the money they have won is worth accessing if they have to deposit money of their own to do so.Casino bonuses, explained in more detail by Casino Brawl, are one of the biggest perks of playing online.Since different casinos operate under a unique set of regulations, it is important to consider the house edge over an individual game’s payout. The rule of thumb should be to go through the terms and conditions that govern bonuses in a casino before signing up. If it is proving difficult to access information concerning how bonuses and rewards are awarded, that should be taken to be a red-flag.
