Robert Pattinson and Kristen Stewart are reportedly playing board games to while away the hours on the Twilight set.
The Hollywood stars - who play lovers Edward Cullen and Bella Swann in the hit vampire movies and are also dating off screen - love playing chess, Monopoly and Scrabble between takes, and are getting obsessed at challenging each other at games, according to The Sun.
Kristen and R-Patz apparently invite co-stars Taylor Lautner, Kellan Lutz and Ashley Greene to "game nights" at the Louisiana set, where filming for the final Twilight movies, Breaking Dawn Parts I and II, starts this week.
A source said: "Rob and Kristen have hours to burn on set and have got massively into board games. It gets competitive. There have been tantrums over snakes and ladders."
