Both online casino and land-based real casinos often offer bonuses to attract more players to play at their casino. The most common bonuses for online casinos including slot casinos are sign-up and reload bonuses, however real land-based casinos usually reward their players by giving out free meals, room upgrades or slot vouchers. Online casino bonuses can be divided into six different types: cashable bonuses, sticky bonuses, cashback bonuses, no deposit bonuses, free play bonuses, and comp points.
Cashable bonus is the free money that the casino will give the player to play slots or any other game at their online casino. The player probably is required to complete a wagering requirement before being able to cash out this bonus. Online casinos usually offer a certain percentage match bonus up to some amount of money like, 100% sign-up bonus match up to $400, this means that on your first deposit, the online casino will double your initial deposit money up to $400, so if you deposit $400 your account will be credited for $800, however you may not withdraw the bonus until you wager $4000 on casino games. Usually, there are restrictions on the casino games that you can wager on, games like roulette, baccarat, craps usually do not consider as part of wagering requirement. The reason is that these bets give the player the opportunity to simultaneously bet on winning and losing outcomes, greatly reducing variance. For example, betting on both red and black in roulette. Online casino might have different policy against wagers on casino games with a low house edge, like blackjack, video poker, and slots which are also often excluded
Sticky bonuses are very similar to cash bonuses, but the player can never withdraw the bonus money given by online casino. So an online casino might offer a 100% match sticky bonus up to $200 with a wagering requirement of $3000, and the player can bet the sticky bonus after meeting the wagering requirement. Regardless of winning or losing, the sticky bonus can not be cashed out, so if the player cashes out $500, the initial $200 will stay in the casino and he will be given $300. Also the player may not cash out any amount of money having a balance below the given sticky bonus. This type of bonus is also known as "non-cashable" or "phantom" bonus.
Another type of bonuses, rarely seen in slot casinos, is cashback bonus. Cashback bonus will be given following a player loss, and this simply is a portion of the player's loss which is returned weekly or monthly. For example an online slot casino might offer a 25% cashback each month, that means 25% of the money lost by a player playing slots will be credited back to his/her account, and any player who has won playing slots will not be eligible to receive the cashback bonus.
No deposit bonuses are the free money given by the online casino or land-based casino, cashable at anytime and the player can use this on any casino games like slots, video poker and etc. without any restriction; however these bonuses are very small size.
Free play bonuses are the play money given by the online casino to play at free part of the online casino, and usually online casinos reward the players if they win a lot of play money by real money which is very small comparing to the amount won in the play money section. For example, when you play slots online at slothill.com, you are playing with play money.
Usually when you play slots or any other game at an online casino, you will be given a comp point with each wager you make on the game like slot. The players can exchange the comp points for cash or other prizes. A casino might offer 3 comp points for each $5 wagered on slots and 1 comp point for each 10$ wagered on blackjack.
