Goofs

When Katie escapes the wax museum & gets in the police car with Noel, she closes the door. When they drive away, the passenger door is open.

When Noel and Katie first escape in the car, the drivers window changes several times from open to closed in quick succession.

When first getting into the white suv the plate reads LPA3 when arriving at the compound the suv with plate LPA3 is parked and they arrive in an suv with plate LPA1.

When Noel and Katie are in the Impala, it shows on the clock that it started at 1:00 p.m.. when they are driving through the warehouse being chased by the motorcycle gang, the clock says 10:58.

When Machine Gun Kelly gets pulled out of the pool his hair changes between shots.

When a lottery "rolls over" the unclaimed money from one lottery is added to the ticket sales of the next to make the new jackpot, but in Jackpot the jackpot is given away every time (either to the "winner" or the person who kills them), so a Rollover is impossible.

Escaping from LA stops the game; no one wins. Traffic jams of people fleeing LA before the drawing are shown during the bus ride. It is entirely possible that multiple 'winners' managed to escape in a row.

If they'd brought Machine Gun Kelly into the panic room with them, they wouldn't have had to worry about him giving up the code. Even if he woke up, he hadn't shown any interest in collecting the jackpot for himself, but they could always stun him again if he did.
