A sticky bonus is a “non payable” bonus, which means the bonus will only be credited for bets in online casinos and deducted from the profit when it comes to a payout. Actually, only a few casinos such as the Playtech casinos use these types of bonuses such as Casino Tropez, Europa Casino or Euro Grand. The bonus amounts are often 200-300% and the turnover requirements are low. Whilst this sounds good as first, the bonus you receive from the casino does absolutely nothing, as you will never be able to withdraw it, it just gives a more credits to wager.
How useful are sticky bonuses? First, the profit possibilities in Playtech casinos are really very modest and payouts are hard to achieve. Secondly, if you should be winning any money with the bonus, you would not be able to withdraw it, as it will be deduced from your profit first. You should better make use of bonus offer other than sticky bonuses to have a chance to actually get the bonus paid out.
