Best Casino Bonuses Online – FAQ

What are Casino Bonuses?

Casino bonuses are incentives offered by online casinos to attract new players and retain existing ones. They come in various forms, such as welcome bonuses, deposit bonuses, free spins, etc.

Can I Claim a Welcome Bonus if I’m Not a New Player? 

No, you can not claim a welcome bonus if you’re not a new player. These bonuses are exclusively for new players.

If someone using the same home or IP address has already claimed it, you will not be eligible.

What Are Wagering Requirements at Online Casinos?

It’s the amount of money you have to spend at a gambling site to withdraw the bonus money. 40x wagering requirements mean you have to spend $4,000 on casino wagers to cash out $100 in bonus cash. You are not obliged to win or lose, only to wager.

What Online Casino Has the Best Deposit Bonus?

We found Ignition to have the best deposit bonus for newcomers. It gives your bankroll a significant boost (up to $3,000) and comes with very low wagering requirements.

Usually, crypto gambling sites feature better bonuses than traditional fiat casinos.

Is a Casino Sign Up Bonus valid for a Limited Time?

Yes, many gambling sites limit the time you can use their welcome bonus codes. It typically ranges between one week and several months.

Are Bonus Spins Valid for a Limited Time at Online Casinos?

Yes, bonus money, free chips, and free spins are all limited to a specific time when players can use them. The validity period can range from a week to several months.

Do Casino Bonus Codes Work on Mobile Devices?

Yes, a mobile bonus is typically no different than a desktop one. Whichever device you use to claim your offers, you’ll score the same bonus funds, free chips, or free spins.

Can I Claim a Deposit Bonus on Any Casino Game? 

Yes, but it’s not always strategic to play all games due to differing contribution rates. Slots usually contribute 100% to wagering requirements, while games like roulette often contribute less.

In detail, a deposit bonus can technically be used on any casino game. However, the effectiveness of this strategy varies based on each game’s contribution towards the wagering requirements. For instance, if you bet $100 on slots, it would fully count towards your wagering requirement because slots typically contribute 100%.

Conversely, betting $100 on roulette, which may only contribute 10%, would only count as $10 towards the requirement. Thus, understanding these varying contribution rates is key to effectively using your deposit bonuses.
