Speed Run 4

Speed Run 4 is one of the oldest and most iconic parkour games on Roblox, built by veteran solo developer Vurse and launched in October 2014. Players race through 30 handcrafted obstacle courses, each with a distinct visual theme and its own unique soundtrack, in either untimed exploration or competitive Time Trial Mode. With 1.72 billion visits and 4.51 million favorites, it ranks among the most-played Roblox games ever made - sustained by polished level design and a movement feel that has kept players returning for over a decade.

The 30 levels span a wide range of visual themes including forest, ice, neon, space, and more, making the experience feel varied despite the consistent run-and-jump mechanic. Early levels introduce platforming fundamentals, while later stages present brutal precision-jump sequences that test experienced players. Casual Mode removes the timer entirely for players who want to explore without pressure, while Time Trial Mode records your fastest completion per level and displays it against others on the server:

• 🏆 Time Trial Mode - records fastest completion per level; competitive layer for experienced players
• 🗺️ Casual Mode - no timer; exploration-focused for players enjoying the visuals and music
• 💎 Moon Dimension - secret bonus area accessible via a legacy code; sought after by the community
• ⏳ Skips - unintended shortcuts through levels discovered by the community; a major skill expression
• 🏠 Donut Update content - new levels, Forbidden Levels, and Secret Levels added in the 2024 update

Community speedrunners actively track World Records across all 30 levels, and the discovery of skip routes remains an ongoing pursuit. There is no currency, inventory, or character customization within the core game - progression is purely temporal (how fast you complete levels) and positional (how far you have gotten).

The code system was added in 2018 and then removed in the Donut Update of 2024. Two legacy codes from before the removal remain of note: one unlocks the Moon Dimension, and one grants a Meme Shout cosmetic. Speed Run 4 operates today as a perennial classic with infrequent updates, and no active codes are available.
