For example, a €10 no deposit bonus with a 50x wagering requirement means €500 must be wagered before withdrawal is possible. Terms and conditions vary, but commonly include a minimum loss requirement, maximum cashback limits, and restrictions on qualifying games.

Terms and conditions for reload bonuses are similar to other casino promotions. For example, a 100% match up to €200 means that if you deposit €200, you receive an additional €200 as bonus funds.
