The bonus is very substantial. However, if you win a large amount of money, you will suddenly be required to submit a very complicated document that has never been seen before. No matter how many times I submit it, I have not received any payment as a real experience.
Again, it took a long time due to a very complicated request, but with the cooperation of GURU Casino, the full amount was collected.

ボーナスはとても充実しています。ただし高額の勝利すると、突然、今までに無かった、とても複雑な書類提出を要求します。何度提出しても、実体験として支払いは受けられていません。
改め、とても複雑な要求で時間が掛かりましたが、GURUカジノさんの協力を得て、全額回収しました。
