What if I deposit more than the maximum qualifying deposit?

There is no maximum. You receive the bonus on your full deposit.

Can I make money with this bonus?

On average no: the expected value is negative (−€40.00). But individual results vary greatly due to slot variance. Some players end up positive, most negative. The casino always has a mathematical advantage.

How long do I have to meet the requirements?

You have 15 days from activation to complete the wagering requirement. If you don't make it, the bonus and any winnings are forfeited.

Do table games count towards the wagering requirement?

Table games count for 10%. Live casino games count for 10%. Slots count for 100%.

How reliable are these calculations?

Our calculations are based on a mathematical model that estimates expected value using the official bonus terms and the casino's standard RTP. It's an approximation: actual results depend on the specific game, your bet size, and luck. Read our full methodology for more details.

Our analysis

Maikel Slomp

Casino777 sits right at the bottom of the ranking. Its welcome bonus carries the highest playthrough requirement we come across, which means the casino on average takes back more in its own edge than the bonus itself is worth. Most sessions end with your deposit at zero before the bonus is ever cleared. If you play here, treat the stake as entertainment, not investment.
