Visible crew/equipment: The scene where Spencer throws the boomerang for the first time and misses the bikers they take off running. While they are running from the bikers, there is a shot right before the boomerang hits the bikers where you can see a camera man sitting in the bushes on the left side. You don't have to pause it, but can to see it better. (00:36:30)
Visible crew/equipment: When the girl is dragged by the motorcycle, she unties herself and starts to walk. A crew member can plainly be seen standing in the background. (01:35:00)
Continuity mistake: The father of Alex is wearing a red scarf in the shot where Spencer and fridge are in front of his house. From another angle when Bethany and her mom see them from the car he's not wearing the red scarf.
Plot hole: Sea-Plane tells the group that he has tried twice to cross the canyon and complete the transportation level. It would have made no sense for him to be completing that level moving toward the jaguar if he didn't have the jewel needed to finish the game. Either he had been given a jewel and it was reset back and given to the new players or there could be more than one jewel in the game but he doesn't mention having his own jewel.
Continuity mistake: At the end of the movie, Spencer is wearing a blue hood jacket when arriving at school. However, when they destroy the gaming unit and game with a bowling ball, Spencer is back in his yellow raincoat. Bethany and Fridge are also wearing different jackets, because outside Fridge is on a vest with a hoodie and a green shirt, and Bethany has on a blue jacket, but inside, Fridge just has on a hoodie and a numbered football shirt, and Bethany has on a multi colored jacket. Also, Spencer has on a black shirt outside, and a blue button down shirt inside. (01:48:00 - 01:50:00)
Continuity mistake: The rocket launcher pods are a bundle of PVC tubes on the prop but correct in CGI shots.
Continuity mistake: When Bethany is taking a selfie, there is a cup on the table to her left, which she adjusts. Throughout the entire sequence of the selfie scene, the handle of the cup can be seen to change directions several times, from pointing straight up (to the top of the screen from viewers perspective) to pointing to the left of the screen. This is noticeable in close up and far shots of the table, as well as overhead shots of the table. (00:04:35)
Continuity mistake: When Martha approaches the men at the transportation shed, the stereo is visible on the bench on the right and its front is parallel to the side of the bench, but when it switches on for the dance fight, it is now at about a 30 degree angle, touching both sides of the bench. (01:10:30 - 01:12:00)
Continuity mistake: Towards the end when the group of 5 are getting ready to go down the lit path to return the jewel, Spencer tells Fridge to hand him the jewel, then when he starts the climb through the trees the jewel disappears. When he falls out of the tree and 'dies', then runs back to his friends, Alex asks if he has the jewel and he takes it out of his pocket, then the very next scene puts his hands on his hips and the jewel is gone again.
