Won't let you withdraw winnings and cancel your account rather than give a bonus - SCAMMERS
By Michelle B.
Worse gaming site I have ever played. They take your money. Bonus are not worth it when u get it. Don’t waste your money is my advice. Hence all the low reviews they have.

Betninja basically scammed me out of 3k. When I lost, there was no issue. But now that I've won, they claim I violated a bonus rule and refuse to pay out. I hope people stay away from this site."

Took multiple payments for 2 transactions so £40 in total got charged £43? Won £106 asked why i got charged extra said it wasn't there problem. Asked for alot of personal details to make the withdrawal come out. Once I refused they deleted my account and have ignored me. This is a copy paste casino so when it shuts down it gets put up again be warned this is a massive scam. Should have avoided when it said you need over £100 to withdraw 😅 customer service is appalling and no help so im £43 down and cant access my account to dispute them sending the winnings complete joke avoid bet ninja and anything similar to this casino. You will get robbed and have dodgey transactions come out of your account. I will be taking this as far as possible so no one else makes the same mistake

COUNTRY BLOCKED!!! got scammed and lost £50 DOH!!!
