Awesome support team

First off I would like to say this game is simple yet addicting. I never put money in, but within the first week of playing I was awarded $2. I was quickly able to turn that into $12. When I went to play the $12 game it froze up, boots me out of the game, and wouldn’t let me play it at all. So I lost my $12 and was a little upset about it, because I never had a chance to play the game. This happened during the holidays in which I knew would probably take forever to get a response and figured they would give me some bs answer and not refund the money. Again it being the holidays, they got back to me within 2 days of emailing them and refunded the $12 right away. I was very happy with how they handled the situation and was able to go on and won a few more getting me to $23. I was able to cash it out. The process for cashing out winnings is a little long, but still. I put no money in and now I’m waiting on a $20 check in the mail. So basically I made $20 for playing a game for free. Can’t beat that. So in the end great game, great support team, and I will continue to keep playing for a long time. Highly recommend it to anyone and everyone. Well to update one thing. Cashing out says it takes 4-6 weeks. I got an email today saying my check is on the way. So it actually only took about 2 weeks. Good stuff.

I was playing for a few weeks but nearly 2000 tickets later I cannot get back into the game. The app says I’m not connected to WiFi even though my phone says it is and my computer is too. I have a feeling they kick people off who won’t deposit any money I had been planning to play for free til I got the required amount of tickets needed for $500. Their ads are misleading they show people sooo excited that they are recommending it but these people and ads never state that you have to play to win they make it sound free but it’s more like gambling (you might want to do research on what is happening with the people associated with the FYRE Festival and why there still is an investigation because there are laws in place for omitting things from ads, there is also discrimination laws, gambling laws, laws to protect the consumers from misleading and false advertising, laws in place to protect people from theft and fraud, plus tax evasion laws for not reporting your winnings). Too bad they won’t let me back in for playing the free games I would have recommend it to people as it is fun but now nope not recommending it to anybody.

Tough Game Critic the first ,

Don’t get the game!!! The good reviews are fake

They ask you to deposit your own money for the game, and they don’t tell you how to play in the first place. I have no idea HOW to play and it won’t let me play another game unless I deposit my own money, which is dumb, Because the game is supposed to give YOU money. It’s a waste of time. Don’t get the game. Also I am starting to suspect that the good reviews are fake. The lengthy ones probably aren’t, However, if you keep scrolling down, the reviews start to get a lot shorter, and they all say the same thing. “I’ve been playing all night! You win real money!” This whole app is very secretive and suspicious. The game is designed so that they get money off of YOU. Also, the opponents aren’t real people, they are just fake..... I’ve seen the same people repeatedly and you never win no matter how good your score is. Also online gambling is illegal in all states except for Nevada, so technically this app is illegal and by supporting it, you’re helping this scamming business grow. DONT GET THE APP!!!!!!!!!
