Information about casino bonuses


Online casinos offer various bonuses to attract and retain players. Here are the most popular types:

  • Welcome Bonuses: These are designed for new players and typically include a percentage match of your first deposit (e.g., 100% up to £200). Some may also include free spins.
  • No Deposit Bonuses: These bonuses allow you to play without making a deposit. They are often small amounts of free cash or free spins.
  • Free Spins: Offered either as part of a welcome package or as standalone promotions, free spins let you play specific slot games without using your own money.
  • Reload Bonuses: These are for existing players, offering a percentage match on deposits made after the initial welcome bonus.
  • Cashback Bonuses: Some casinos offer to return a percentage of your losses over a specified period, softening the blow of an unlucky streak.
  • Loyalty Rewards and VIP Bonuses: Designed to reward regular players, these bonuses include perks like free spins, cashback, higher withdrawal limits, or even personal account managers.
  • Live Casino Bonuses: These are aimed at players who enjoy live dealer games, offering tailored rewards for blackjack, roulette, and similar games.

Key Terms and Conditions for Casino Bonuses

Casino bonuses often come with terms and conditions that dictate how they can be used. Familiarising yourself with these terms is essential to avoid surprises:

  • Wagering Requirements: This is the number of times you must play through the bonus amount before withdrawing any winnings. For example, a £100 bonus with a 30x wagering requirement means you need to wager £3,000.
  • Game Contribution: Not all games contribute equally to wagering requirements. Slots often contribute 100%, while table games like blackjack may only contribute 10%-20%.
  • Minimum Deposit: Bonuses often require a minimum deposit to activate. This is typically between £10 and £20.
  • Maximum Bet Limit: While using a bonus, casinos may cap the maximum bet size (e.g., £5 per spin or game round).
  • Expiry Period: Bonuses are usually valid for a limited time, such as 7 or 30 days, after which they expire.
  • Eligible Games: Some bonuses can only be used on specific games, so make sure to check which ones qualify.

What to Consider When Choosing a Casino Bonus

Not all bonuses are created equal, and selecting the right one depends on your preferences and playing style. Here are some factors to consider:

  • Wagering Requirements: Look for bonuses with low wagering requirements, as these are easier to turn into real money.
  • Bonus Size vs. Usability: A huge bonus might seem appealing, but if the wagering requirements or game restrictions are too high, it may not be worth it.
  • Game Preferences: Choose bonuses that align with the games you enjoy, whether it's slots, live casino, or table games.
  • Reputation of the Casino: Ensure the casino is licensed and regulated by a reputable authority like the UK Gambling Commission to guarantee fair play.
  • Payment Methods: Some bonuses exclude specific payment methods, such as Neteller or Skrill, from promotion eligibility.

Understanding Wagering Requirements


Wagering requirements are the conditions set by online casinos that determine how much you need to bet before you can withdraw winnings earned from bonus funds. Simply, they represent the amount of money you must wager to "unlock" your bonus and turn it into real, withdrawable cash.

For example, if you receive a £100 bonus with a 10x wagering requirement, you would need to wager a total of £1,000 (£100 x 10) before you can withdraw any winnings from the bonus. The higher the wagering requirement, the more difficult it can be to meet the conditions and cash out your winnings.
