Every online casino will specify which games are allowed. It is important to read the terms and conditions associated with the No Deposit Bonus outlining the rules.
There are several reasons a player may not be eligible and depends on the terms and conditions of the offer. Reasons for not qualifying include restricted country, claiming two bonuses in a row, two players residing in one household sharing the same IP address, bonus abuser, and in certain circumstances online Casino groups allow only one free chip among their brands.
The bonus or credit is paid for by the house (casino), it has the same value as cash and can be used to play any type of casino games including blackjack, craps, slots, video poker, roulette, and even less popular games such as scratch cards and keno. But both the credits used for playing and the winnings (if there were any) still belong to the casino. In order for that cash to exchange hands and end up in the player’s pocket then the player needs to wager both a good amount of time and money.
