Continuity mistake: The third tape player is hanging from a string in some shots, but a cord in others.

Continuity mistake: When Jeff sees the mini Jigsaw puppet on the tricycle, the handlebars are just red in one shot, but then they turn grey. (00:56:10)

Continuity mistake: The tear on Jeff's cheek briefly switches sides when he is holding the third card.

Low Cow

Revealing mistake: When Jigsaw is coughing up blood, the tube pumping the blood is visible. Look near his thigh. You can even see some red liquid oozing up. (Only visible in widescreen.) (00:38:20)

Revealing mistake: After Jeff shoots Amanda she falls to the ground. You can tell it is a dummy, just watch her arms and head.

Visible crew/equipment: Just before Amanda shoots Lynn, a mini microphone can be seen on Amanda's neck. It is only visible for a few seconds then vanishes, so look quickly.

Other mistake: Near the end of the film when Jigsaw has the tape player, the 'play' button is near the left side. But Jigsaw's finger is on the right side, not even close to the play button. Jigsaw presses on the right side where there isn't even a button, but the tape begins to play anyway although nobody pressed the actual play button.

Low Cow

Continuity mistake: The model of gun Amanda has when she shoots Lynn changes between shots.

Low Cow

Continuity mistake: Jeff's saw that he used to slit Jigsaw's throat is drenched in blood. Throughout the scene the blood stain gets shorter and longer.
