- Revenue scales into the hundreds of millions per second
World 4 [W4] (community-modelled)
Current endgame- World 4 is live in the current build (game updated September 16, 2026)

How to Eliminate Tycoon Bottlenecks
The 3 most common mistakes that stunt Cash Per Second growth in Drive-Thru Empire.
Ignoring Order Intercom Speed
If your kitchen cook time is 2 seconds but your Intercom takes 7 seconds, your cooks stand idle. Always upgrade Intercom until incoming orders never bottleneck at the speaker.
Wasting Starting Luck Boost
Code LUCK301 grants 30 minutes of Luck. If you redeem it with no cash to roll with, the window expires unused. Bank some cash before you redeem it.
Delaying DRAIN CCU Group Perks
The developers advertise rewards for joining the official Roblox group, and joining costs nothing. The exact bonus is not published, so join early and treat the size of the perk as unverified.
Frequently Asked Questions
Common questions about Drive-Thru Empire mechanics and codes.
Is Drive-Thru Empire related to Driving Empire?
No. Drive-Thru Empire is a fast-food restaurant tycoon game created by DRAIN CCU Games where you build a drive-thru and roll for supercars to serve. Driving Empire is a separate car racing and driving simulator created by Voldex.
How do I redeem promo codes in Drive-Thru Empire?
Launch the game on Roblox, look for the "Codes" button located in the bottom-left corner of the screen, type or paste the code exactly as written, and click Submit to receive your reward.
What is the best station upgrade priority?
Always upgrade Order Intercom first until order intake matches kitchen cooking speed. Upgrading the Grill without Order Speed creates an empty kitchen, while upgrading only Grill leaves cars waiting at the entrance.
How do Luck boosts work on supercar rolls?
The working LUCK301 code grants 30 minutes of Luck. The developer does not publish the exact size of the boost; the source only states that your rolls have a better chance of landing rare, exotic or cosmic cars while it is active.
