Never saw such a rule on a casino site (and I have used a lot of them) and this is just ridiculous. I can understand that you would need to make a valid bet if you received "free" money from a free bet or a promotion but a 100$ bet is quite extreme. If they continue to create these rules, there will not be a lot of players left to play on the site lol.
Indeed. Besides that, the free money is not too high compared to what we use for bets so I do not think it attracts the players to spend their money to chase the "free" money. Maybe they will still play gambling on that site but not for the free money as they do not have an intention to get that because they can get it from other places. They should change these rules because that will not make their members comfortable with that but that will be up to them if they still want to use that rules.
But imagine you play with that money and you reach $100 and you can't withdraw, you still need to play all in... and I guess it's easy to place some bet on x1.01, but it would be crazy if you lose it all on that payout after all that gambling...
@TopTort777 thanks for the info! I am glad you had fun gambling with free money, I hope the next time you will reach to withdraw, even with this crazy rule!
