At the start of the round, the game chooses three random players as judges. The other players are selected as models. The game chooses a random category that the players must base their outfit on.
The models are teleported into the fitting room, where they can choose what they want to wear that is available. The models have a limited amount of time before they are released onto the runaway with the clothes they have on.
The models will walk on the runaway one at a time, having the judges vote on their outfit from a scale of 1–10. When a model is done posing on the runaway, they will be teleported to the bleachers on the sides of the runaway.
Once all models have walked on the runaway and had the judges vote on them, the game will announce the winner, give them 200 points, and start another round. If there is a tie, the game will announce the tied players, distribute the 200 points evenly, and start another round. Winning players receive one win and points.
In August 2017, the developer changed the name from "Roblox's Top Model" to "Top Roblox Runway Model".
