▶ DOWNLOAD NOW AND UNLEASH THAT DOG
So I've been on Underdog for over a year now and I've never had any issues up until I had a few tennis matches that were canceled so Underdog refunded me my money so I withdrew well over half the money and the money I had left on there I made some basketball tickets with so I tried to deposit some more money on my underdog account to do halftime bets and all of sudden I had a deposit limit. I've never set a deposit limit on my Underdog account. So I couldn't make a deposit for 90 days, 3 months!! That's a little harsh if you ask me and my thing is we can't make another account to or they will block your Underdog account permanently. Seriously? If we are depositing money and we don't always win and Underdog is making money off of us why does Underdog permanently blocks people accounts for making a new account to gamble on?? That doesn't make any sense to me at all. It's really harsh. I love Underdog and like the anticipation of it but some of the rules are a bit immature.
They’ll make sure you never win

Worst betting app I’ve ever used. And for me, that’s saying something, as both fanduel and draft kings are blocked in my state, so I’ve been banished to the depths of my state sportsbook and even THAT I prefer over underdog. Blatant false claims for the pick-em entries just to make people throw away money. They make it seem like hitting 3 out of 3 picks will get you 6x money and hitting 2 of 3 will give you 3x, but in reality, 2 of 3 only gets you your money back. Selecting insurance states “hit 2 or more picks to win” but in what world do you only get your money back on a “won bet”? They need to phrase this better and say the bet will be voided, not won. Also in the pick-em rules it states “Payouts include entry fee being paid back” which is not the case if you select insurance. This makes it seem like you’ll at least be making +100 on 2 of 3 but in reality you don’t get anything. Despite all of this, I was actually about to give them my business today on another pickem. I had 4 selections picked out, 2 of which were rescinded minutes after I selected. Do not select ANYTHING until you are ready to actually submit the bet. The fact that two of my promising, well-researched picks were rescinded minutes after I selected them, makes me almost positive that they are monitoring your picks before you even make them, and adjusting them accordingly so they’ll always come out on top. If I could rate 0 stars I would, don’t give these grifters your money.
Horrible
Pursuityourslooksrizz
Arguably the worst app off all time. They trick you thinking it’s good with these promos, don’t be dumb and fall for it. I got 50 people to switch apps and they all agree chalkboard and sleeper are way better. After I signed up, put in my information somehow my account gets locked 4 days later, they claim it is normal and happends to most accounts. By looking at the reviews it happend to almost everyone. They asked for the exact same information that was verified when I signed up. Exact information, even though when I signed up I was verified and my information was correct and I was all good. Next up they started asking for weird information which is completely uncalled for. I try to contact there help team, they respond in 24 hours, I’ll respond back in 10 mins and have to wait another 24 hours. You have to use your bonus money quickly and mine is going to get taken away because my account is locked and they are allergic to responding to legit people. After you open up a case, they take forever to reply and the help agents are never active. I provided them all information possible, everything they need and my account is still locked, insane. $700 down the drain and my friend got scammed by them for 4k. It won’t let me request a withdrawal and my account is locked so I can’t bet. Extremely frustrated, a lawsuit might be filed. This is ridiculous, can’t believe I fell for this scam

Consumer beware

I was happy to find a way to get in a sport that does not allow sports betting yet. But underdog is a disaster of an app and company. Practices are predatory, customer service offers you nothing but leaves your pockets empty. When you win with a “bonus” the overwhelming majority of your “winnings” go back into bonus money. It does not matter if part of that money was your “real money.” This is also never explained to consumers and leaves you scratching your head when you finally do win. Not to mention the insane chances of hitting two parlays. If you have another option besides underdog PLEASE use that option. I really wonder why people still choose to use underdog. It is so incredibly unlikely to hit two parlays AND THEN underdog makes it more difficult when you can’t bet two props from the same player or same team. If you’re reading this…please bet your money elsewhere. Go to a casino or give it to a friend, do not give it to this predatory company. Also when a prop becomes popular in vegas underdog will change the odds in their favor and force you to bet something higher bc it is popular in vegas. This company does not care one iota about their consumer. Please put your money to other uses. Do not support this company, they should be ashamed of themselves. This is coming from a bettor who has actually profited from betting on underdog (not a salty consumer who lost with them, just a concerned one telling other ppl there are BETTER ways to bet and better customer service-also better apps with more transparency).
