Continuity mistake: The third tape player is hanging from a string in some shots, but a cord in others.
Continuity mistake: The tear on Jeff's cheek briefly switches sides when he is holding the third card.
Continuity mistake: When the movie opens, Eric is in the bathroom and looks over at Adam, who is leaning up against the wall. However when we see Adam in Saw 2, he is propped up against the pipe. Eric hasn't moved him, as he's chained up. Obviously when they set up the bathroom for this movie, they did not put the dummy Adam in the same place. This scene takes place immediately after the scene in Saw 2, and thus there's no time for the body to have been moved at all. (00:00:50)
Continuity mistake: In the "pig" room the string around the tape player suddenly disappears in the middle of the tape message. Jeff's right hand never changes position and the string was tied around the middle of the player, he would have had to move his hand to get it off. (00:58:00)
Continuity mistake: When Jeff finds the second box (after the freezer room) he takes the card and flips it over to see the picture on the back. In the closeup his thumbs are on the bottom corners, but then the shot cuts away to a view from his left and you can see that his left thumb is at the top left corner and his right thumb is as least halfway up the card (instant cut, no time to move his hands). (00:48:30)
Continuity mistake: The blood stains (streams) on Jigsaw's chest constantly change after Jeff slices his neck. Sometimes the only blood stain is a trail that goes directly down the side of his hospital gown, other times it's halfway down his chest. The shots constantly go back and forth, so it's not just the blood flowing down his chest.
Revealing mistake: When Kerry is in the Angel trap there is a close up of her about to put her hand in the acid for the first time before it changes to a spinning shot. In the close up, watch very closely and you will see her fingertips enter the acid but she doesn't get burned or scream in pain. (00:15:40)
Continuity mistake: There is a smear of blood on Jeff's right temple that disappears in the shot right after he drops the saw blade. It reappears in the very next shot.
Continuity mistake: When Jeff flips over the 3rd card he is holding it with his left hand by the left edge of the card, but when the scene (instantly) cuts away to a view of in front of Jeff you can see the he's holding it by the bottom (look at the way the card it bent).
Plot hole: Out of all of the chains Troy had attached to him, one is hooked to his jaw which is near impossible to do as that would probably kill you and ripping it out would too, which is why Amanda would have placed it there. Jigsaw wouldn't have approved of it, and obviously there's no indication that Amanda had a medical profession, so how did she hook that chain to his jaw and even if she did, without killing him?
Revealing mistake: After Jeff shoots Amanda she falls to the ground. You can tell it is a dummy, just watch her arms and head.
Suggested correction: First of all, she doesn't fall to the ground. She stumbles after being shot and then slowly collapses to a seated position. There is also no dummy being used, as Shawnee Smith's face is visible in every shot of her until she dies.
Suggested correction: You don't always feel the pain straight way when under immense physical stress.

What about not being burned? That's still a mistake.
