We are giving away free All-In Poker bets on a daily basis for those who complete the challenges. There is no limit to the number of free bets that you can earn.
The easiest to complete are The Multi Challenge and 4 of a Kind Challenge.
To complete the 4 of a Kind Challenge you simply have to deal yourself any pocket pair, and once you play enough you will eventually hit 4 of kind.
More details on the challenges can be found here :

Tip - How to maximize your All-In Poker winnings with Ten Jack SuitedTo maximize your All-In Poker winnings you should take advantage of the free bets that we award for completing challenges.
Whenever you win a single bet with a Straight Flush using both of your hole cards you will earn a free bet bonus at the size of 3 times your winning bet stake, and whenever you hit a Royal Flush you will earn a free bet bonus at the size of 10 times your winning bet stake.
Your goal is therefore to give yourself the best possible chance to hit a Straight Flush or a Royal Flush and the starting hand with the most chance to do it is Ten Jack Suited !
Make sure you don't give the dealer any hand that includes one of the cards that you need to make a Straight Flush or Royal Flush. For example, if you give yourself Ten of Hearts and Jack of Hearts, make sure the dealer does not have any heart 7 or higher as this will reduce your chances of winning the bonus.
Finally, did you know that Ten Jack suited has the best chance from all the starting hands to beat Pocket Aces ?
This is important because one of the tasks in the Multi Challenge is to crack pocket aces, and Ten Jack suited is the best hand to do it with !
I hope this tip will help you put some extra winnings in you wallet.
Good Luck !
