The fourth event of Last Marble Standing was held on 11th June 2020, featuring the fourth event, Collision.
The formatting of this event was similar to that of the Collision event from the Marble League Showdown 2019. However, there are only 2 groups, as opposed to 4. Each marble team rolls down a slope before colliding into each other. The aim is to stay in the arena. Unlike in previous collision events, the number of point the team earns is the number of marbles from their team left in the arena, rather than the number of the opponents team that are knocked out of the arena. There are dominoes around the edge of the arena that can be knocked over. Ball bearings on slides are spread around the arena and can be fired into the arena by pushing their slides.

- Two production errors occurred during this event.
- The first error occurred before the match-up between The Freshers and Graze of Glory. In the on-screen graphic that appeared before the marbles were released, the logos for The Freshers and Graze of Glory were depicted as the logos for Graze of Glory and Dairy Dash, respectively. The error was rectified in the results graphic for the match.
- The second error occurred in the graphic depicting the result of the finals match. It displayed 5 - 4 (where teams score points for knocking off opponent marbles) instead of 1 - 0 (the current scoring system).
