Continuity: In the shots before Danny throws the rugby ball, which knocks the glass over, the position of items on the desk keeps changing, and a computer mouse appears next to the glass of juice between shots.

Continuity: After the rugby ball knocks the glass of juice over, the juice spills all over a drawing that the Dad needs for work. Between shots the position of the spilt juice on the drawing changes.

Continuity: When Danny throws the rugby ball across the table at Walter, which knocks the glass of juice over, the ball also knocks a photo frame over. In the next shot the photo frame is standing upright again.

Continuity: Danny has plasters on his right elbow. During various scenes, they appear and disappear. Also they once changed design. And around the end of the movie, the plasters disappear from his elbow and appear on his right hand.

Deliberate "mistake": The turn count for Lisa's stay in the Cryogenic Sleep Chamber is off. The card reads she should be there for 5 turns. 'Turn' can either represent a single move made by either Danny or Walter, or a complete game cycle where both Danny and Walter have made a move. If we count the turns by player, it comes to 8 and she's awake 2 turns too late as it should have happened at the start of 6th. If we count both players’ moves together as a start of a turn, then she's awake 2 turns too early as its turn 4 and not turn 6. It seems obvious from showing us the shower suddenly start up that this is the correct point in the film they wanted her awake, so it's unlikely she was actually awake off-camera during the Astronaut's arrival and we just didn't see.

Continuity: When Walter is watching SportsCenter, and Danny is complaining that he was watching SpongeBob, he changes his position between the a closeup of his head and a wideshot of him.
