On June 8, Roblox's higher DevEx rate for eligible novel games went live. Roblox previously said the 42% increase applies to spending from age-checked players 18+ in the United States and is designed to support teams building deeper games for older audiences.
A DevForum recap marked the launch with the new rate of $0.54 per 100 Earned Robux. The key condition is eligibility: games must qualify as novel games and use R15.
The raise is narrow by design: it rewards a specific slice of the catalog rather than all spending. For studios the math still shifts materially — $0.54 per 100 Earned Robux is a 42% premium over the standard rate, and at scale that premium can decide whether a team builds its next game for adults or for the broad all-ages middle.
