"je me suis loggé sur jupiter club casino j'ai eu 20 euro de bonus - j'ai un gain actuel total de 306 euros. J'ai contacté le casino et reçu comme réponse pour pouvoir retirer les gains ceci: "you need to play 30 time through before they may be cashed in ".
"cela veut dire qu'il te faut jouer 30 fois le montant du bonus avant de pouvoir encaisser , soit 600 euros de mise ."

"Signup bonuses
Many online casinos offer signup bonuses to new players making their first deposit. These bonuses normally match a percentage of the player's deposit with a dollar maximum, and almost all online casino signup bonuses require a minimum amount of wagering before allowing a cash out. Gameplay at specific casino games might be excluded from the wagering requirement calculation.[citation needed]
A fictional signup bonus offer follows as an example:
* The online casino offers new players a deposit matching bonus of 100%, up to $100
* The player must wager 25 times the total amount of the deposit plus the bonus before withdrawing
* Wagers on baccarat, craps, roulette, and sic bo do not count towards meeting wagering requirements
For this particular example, this would mean that a player depositing $100 would start with $200 in his account. The player must make $5000 ($200 × 25) in wagers before being allowed to make a withdrawal."
