Online Casino Welcome Bonuses - Terms & Conditions [Must Read]

It’s very important to make sure thay you understand how terms and conditions work for online casino bonuses. All promos come with their own, specific T&Cs, but here are the general overview of how they usually look:

• Minimum Qualifying Deposit: In order to qualify for a welcome bonus, or any other promo, you must make a minimum deposit. Every casino is different, but most sites will allow you to get a piece of the action with $10 - $20 upfront.
• Deposit Methods: Some casinos require you to use a specific deposit method to activate certain bonuses. In many cases, Skrill & Neteller deposits are excluded.
• Wagering Requirements: Before you withdraw winnings from the bonus, you’ll have to satisfy wagering requirements. For example, Slots.lv’s 300% match up to $1,500 comes with a 35x playthrough.
• If you deposit the minimum of $20 to qualify for this offer, you’ll have $60 in your account.
• Game Contributions: Different games contribute different percentages of each wager towards your playthrough requirement. Slots usually contribute dollar-for-dollar, but table games & specialties may only fork 10-20% of each wager towards helping you cash out.
• Cap on Winnings: Not every online casino has a cap on real money winnings, but some sites limit the amount of bonus cash you’re able to win using a bonus. Cashout restrictions are more commonly found with high-percentage bonuses.

How Do Wagering Requirements Work?

Wagering requirements are conditions imposed by online casinos on sign-up bonuses to prevent immediate withdrawal of bonus money.

These requirements dictate how much a player must bet before withdrawing winnings earned from a bonus. For instance, a $100 bonus with a 10x wagering requirement means the player must wager $1,000 before withdrawing any winnings gained from that bonus.

Typically, different games contribute differently towards meeting these requirements. Slots might contribute 100% of each bet, while table games may contribute less due to their lower house edge. Players must carefully choose games that contribute more to fulfill these requirements efficiently.

Sometimes, meeting the wagering requirement is easier said than done – especially when you don’t know the exact terms and conditions of the bonus you are using. Make sure to always have a closer look at the fine print. It’s very common that not all games contribute towards meeting the WR, so make sure to only play those that do count.
