Plot hole: Spoilers. It's revealed that the barn game takes place at an old farmhouse owned by the family of Jill Tuck - Jigsaw's widow. It's public knowledge that she was married to Jigsaw and that buildings they owned served as the headquarters of several past traps, so the barn should have been investigated at some point in the meantime. Ten years have passed. It makes no sense that the barn was never investigated and that the bodies of the barn victims were never discovered.
Plot hole: Buddy is seen at the end of the movie going on the bus that will be featured in Jeepers Creepers 2. When the students and staff encounter the Creeper why didn't he inform anyone that he had encountered the Creeper earlier? The only person that seemed to know anything was one of the girls having a premonition.
Suggested correction: Buddy is getting on the bus to go to the basketball game. When the second films begins, the kids on the bus are celebrating their victory. Presumable Buddy just stayed in the other town for the night or got another ride home.
Plot hole: Derek, who escaped the mental hospital by pretending to be his twin brother Tyler, was able to locate Tyler's vehicle by using the keys to beep its horn. Once inside the SUV, he apparently found Tyler's cell phone, which is odd because most people carry their cell phones with them. But Derek did not ask Tyler for his cell phone's password before rendering him unconscious - so how did he gain access to the cell phone without the password? (It isn't likely that Tyler previously gave it to him). (00:20:40)
Suggested correction: Tyler never left his cell phone in the car. He had with him when visiting Derek. We see him pull out his cell phone to show Derek a picture, so the phone was already unlocked, assuming he locks it with a password in the first place.
I haven't had time to finish posting the rest of the mistakes I have, but I just uploaded two that should show up under "pending submissions." They probably should have been posted before the one above. I suppose the real question is where the cell phone came from each time.
Suggested correction: The game was unknown to police even 10 years after John died. Now they've found all his other games and his multiple lairs. There would be no need to continue the search.

Hogwash. They would have definitely searched known properties associated with Kramer and his family.
I agree. In the second Saw movie, the police discover that John Kramer is Jigsaw. With this knowledge, not only would the police be able to freeze his assets but, they would be able to look into his financial records and look into any properties he owns like houses, warehouses, etc. Since the cops now have a face and a name, it's a very big plot hole why they never searched his home or any other places. If they had, more traps would have been found and confiscated.
