Continuity mistake: As Hank is having his discussion with Cotton in the Casino you can see Cotton's red (playing) chips in front of him. In one shot Hank stands up and the angle shows Cotton from over Hank's shoulder and the red chips look black and badly damaged. The next shot from the same angle the chips are back to being red and completely fine.
Continuity mistake: Before Cotton puts down "8 the hard way" on the craps table, there is a beer on the table next to him. After he loses, he gets onto the table and you can see the beer has disappeared and he is not holding it. Even in the final shot through the security camera monitor, the beer is nowhere to be seen even on the floor. Also, Hank was holding a beer before Cotton leaped onto the table and in the security monitor footage he has not put it down on the table and is not holding it as he puts both hands on his head.
Continuity mistake: During the scene where Hank is talking to Bobby in the garage about the baby, Hank is wearing brown shorts and sitting on a stool. When Hank stands up you can see the top of his pants are now blue, the same color as his usual pants. When Bobby passes in front of him, he has brown shorts on again.
