We'll explain everything before the game starts but:

Plays pair up first and then sit in tables of 8 (4 pairs) with one dice per table.
Players take it in turns to throw the dice.
When a player throws a six they draw the body of their beetle.
They can't draw the legs or head until they've drawn a body.
The round ends when the first person in the room draws a beetle with 6 legs, 2 wings, 2 eyes and 2 feelers and shouts BEETLE

Everyone tots up their scores - 1 point for each part of the beetle drawn
The highest scoring pair of plays from each table move clockwise round the room while the lowest scoring pair move anti-clockwise.

The pair of players at the end of night with highest total score get a prize.
