My friend plays on Bovada and just hit me with this nice little roll.
bare with me:
First he moved his entire balance back to Bitcoin wallet.
Then re-deposited 1k with the welcome slot bonus (which is $500 max)
After making sure he had the bonus funds, he took his playable balance and signed up for future tournaments thus making his playable balance locked up in future tournaments and leaving his bonus.
So in essence, he's playing with his bonus, while his money is locked up in tournaments. He has to constantly watch that because he didn't want to actually play any tournaments.
So here's the key: with the $500 in bonus funds, to be able to clear the and get the bonus, you have to wager 25k. (if he had deposited lower, it would've been a lower bonus, and a lower clear amount)
Now every time you spin in the slots, for $50 (free play bonus money) and above, it will give you money (like a dollar or 2) whether you win or lose the spin. If you win the spin, you get more.
so basically.....deposit, get the bonus, sign up for future events you're not going to play, and use your bonus to spin the slots for the free money they give you for every spin (it varies on if you win or not).
