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: The nuclear codes are stolen and the Russian guy holding them was let go by Dom. He would contact his government to let them know and the codes changed. Cypher would also know this so her plan is flawed.
Plot hole: The world depicted features magic, an evil overlord who 2,000 years before tried to conquer the world, and several races. Despite these HUGE differences with our world, everything turns out of the same as our world, with nations as they are now, and a casual mention of the Alamo and "Mexicans still getting shit" for it. So our current history has not been altered a single bit by wizards, dragons and super-strong races roaming the Earth. Fine. In this ungodly implausible context, orcs live with humans in cities that mirror ours; humans and elves don't trust them, but still they live in towns with them, they go to schools, run businesses, half of the NFL is formed by orcs. Even the movie Shrek exists! And yet, at the end of the movie Nick Jakoby becomes the first Orkish police officer in the USA! There is just no way a society like this, mirroring closely our own and with orcs that existed as long as humans did, can exist with no orc ever been part of law enforcement.
Plot hole: Eddie estimates that the bad guys will break through Montclair in 30 minutes. Since they already broke the doors with the first car, and all that remains is a pile of rubble (with a forklift behind, even) that does not stop the passage of a person, it's hard to understand what would hold them back that long.
Plot hole: Henry was having headaches and blurred vision, which he attributed to stress. He told the doctor he never considered a brain tumor. Henry started planning how to protect Christina but a sudden severe seizure was an emergency that resulted in surgery and hospitalization; Henry never returned home, but was writing in his red book at the hospital. The tape recorder with step-by-step instructions for his mother was in the safe - if he didn't know he was gravely ill, he wouldn't have prepared it.
Plot hole: When Doc outlines the plan to rob the Perimeter Trust bank in Dunwoody, he says it's "right next to the Buford Highway" which allows for a quick getaway. In reality, Buford Highway is multiple miles away from Dunwoody, with the section of the road the truck chase quickly transitions to being nearly 7 miles away. Similarly, this segment then quickly transitions to the John Lewis Freedom Parkway just east of Interstate 75/85, which is another 4 miles away.
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.
