The M25 is a light party-ish game revolving around the circular M25 Motorway. On their turn, players pick up a card and do what it says - anything from a simple move to a full-blown charade, with drawings and lip reading possibilities.

By doing the action correctly, the player then gets to move further around the M25. The aim of the game is to be the first to reach central London and find a parking space, which is done by rolling a 6 on a six-sided die.
