What Are Casino Bonuses?

Bonus promotions are offered at many online casinos that promise to provide players with free cash for use in their real money casino games in CA. While some sites may offer a no deposit bonus, Casinos in CA most often base their offers on your deposits.

You will most often see a sign-up or reload bonus referred to as a deposit match bonus and structured something like this: 100% match up to $3000.  In this example, the casino is offering to match 200% of your deposit up to a maximum amount of $3000.

So, if you deposit $100, the casino will give you an additional $100.  If you deposit $3000, the casino will give you an additional $3000.  If you deposit $4000, the casino will give you an additional $3000 as their contribution maxes out at $3000. (This is just an example – bonus offers vary from casino to casino.)

There are terms attached to casino bonus offers in CA that players must complete before winnings can be withdrawn. Further details are provided in the following sections.

How Do Online Casino Bonuses Work In CA?

To find out what each California casino site is offering, simply visit the promotions section of their site where they will list the specific bonus and how to claim it. You’ll usually find this section either in their menu or a tab at the top of the home page.

Once CA players decide on the offer they want to accept, they can either enter the promo code when making a deposit or toggle the yes/no switch inside the pay window, depending on how the casino has it structured. Bonus cash will be uploaded to accounts when the deposit completes unless otherwise noted.

Withdrawals that include winnings from using the bonus can only be requested once all the terms and conditions are met, which really means the wagering requirements for playthrough. Some casinos require playthrough for the bonus cash and your deposit, while others only subject the promo funds to rollover.

Be sure to read through all details of California gambling bonuses before accepting one. Using them is not required to become a member.

Types Of Casino Bonuses Offered In California

New Signup Bonuses
Reload Deposit Promos
Cryptocurrency Casino Bonus Offers

California gambling sites love them some cryptocurrency. When players deposit with Bitcoin, Ethereum, Cardano, Dogecoin, or other crypto coins, the casino bonus cash totals and percentage amounts begin to climb. Terms are often easier to complete as well.

Game-Specific Bonuses

Other Types of Online Gambling Bonuses

California Poker Bonuses – Online poker games are offered at most of the gambling sites mentioned here. Some provide poker-specific bonuses that work differently than those extended for sports betting or casino games. Poker promo cash is often awarded based on the number of hands played and dollars risked. The more you ante up, the more free money can be acquired.

CA Sportsbook Promos – These sports betting bonuses work a lot like casino promos in that they usually require playthrough conditions. The rollover terms are often much friendlier than casino bonuses.

Best Casino Bonus Cash Offers

The term "best" is subjective. We would consider the best bonuses to be the largest ones that include the most favorable playthrough terms. There are online casinos out there that strategically make it impossible to meet the Ts&Cs and never intend for you to benefit.

We have personally vetted the casinos you see listed on this page and all of them offer reasonable terms for their bonuses and promotions, even exceeding industry standards.  None of them offer these incentives with nefarious intentions.

What Is Rollover/Playthrough?

A common California online casino condition for withdrawing bonus cash is playthrough or rollover. This means the number of times the promo cash must be gambled before winnings can be requested. Some gambling venues require playthrough for both the bonus and deposited funds, but others only apply it to the bonus portion.

Here is how the playthrough would work at California casino websites in both cases.

  • Bonus Funds + Deposited Cash Promos - $100 total deposit and bonus with 10x playthrough means $1,000 must be gambled before a payout can occur.
  • Bonus Cash Only Promos - $100 total deposit and bonus ($50 deposit/$50 bonus) requires $500 worth of gambling at the CA casino.

How To Satisfy The Terms Of A Casino Bonus – Which Games Matter?

When satisfying the terms of a bonus cash offer, gamblers need to consider the fulfillment rate for each game. Most CA casino sites feature a chart that breaks down how gambling in each game works toward the terms of bonuses.

Generally speaking, games that are based on pure luck contribute at a higher percentage. For instance, slots typically repay at 100%. Table games, video poker, blackjack, backgammon, and roulette contribute toward the terms at 20% or below in most cases.

Craps and live dealer games typically do not contribute to the bonus completion terms at all. Just be mindful of how these conditions can be repaid and you’ll be able to withdraw your winnings much faster.

Should I Accept An Online Casino Bonus?

A bonus that is favorable could be defined for each player in California using the following logic – The casino bonus I accept will be the one I can definitively complete. For us, this means only claiming promo cash with terms that can be completed within our normal gambling activities.

All the online casinos featured on this page offer bonuses with reasonable and attainable wagering requirements. However, if the conditions of a gambling bonus aren’t met within the allotted time, the promo dollars and the associated winnings are forfeited. Avoid this by making a sound strategy based on your realistic gambling schedule.

Slots usually carry the highest fulfillment percentages, so consider playing these games in order to get your payouts faster.  Other games, particularly those involving strategy or decision making by players, contribute at a much smaller rate to fulfilling the terms of the offer, so you’d have to play longer and bet more money to satisfy the Ts & Cs.

If you are concerned about the playthrough terms, you can consider making a smaller deposit. It will be less money that must be gambled through in the casino so that your winnings can be collected sooner – however your bonus amount will also be smaller.

Yes! Just play it smart and accept the casino promo that you can complete. Don’t max out the bonus cash offer unless you intend to gamble a lot over the coming weeks or months, depending on what the terms require.

Again, "best" to our staff equates to the gambling bonus we can easily qualify for. If it is a $1,000 bonus with 10X rollover, don't accept it if you don't intend on gambling $10K before the CA casino’s deadline.
