4x4 Cars Obby is a driving obstacle course on Roblox with 400 levels spread across three worlds, and more than 70 cars to collect from the in-game shop. This guide covers how to get started, how the worlds are structured, how to earn and spend in-game currency, and how Rebirth works.
In shortBuying your first car and hitting early checkpoints gets you into the game's rhythm right away.
When you first load in, head to the shop and buy a car. Once you are in a car, drive through checkpoints one by one. The early milestones at 5, 10, 25, 50, and 100 checkpoints each mark real progress and unlock badges along the way.
Buy a caropen the shop and make your first purchase to unlock the First Car badge.
Hit checkpoint 5your first numbered milestone on the course.
In shortEach world ends at a fixed checkpoint, so use those numbers as your medium-term targets.
The 400-level course is divided into three distinct worlds. Clearing one world unlocks the next, and each has a specific checkpoint where it is considered complete.
World 1
runs up to checkpoint 100, where Heavens World unlocks.
Heavens World
unlocked at checkpoint 100, completed at checkpoint 200.
Summer World
unlocks after Heavens World is done, completed at checkpoint 300.
In shortCurrency is earned through play and spent entirely in the car shop.
Currency accumulates as you play, and the only thing you spend it on is buying cars from the shop. Collecting more cars unlocks additional badges. Every currency milestone from 100 dollars up to 1 million dollars has its own badge, giving you a ladder of goals to climb.
Tips worth knowing
Earn 100 dollars to unlock the First Cash badge — your very first currency milestone.
Keep playing to pass 1,000, then 10,000, then 25,000 dollars in turn.
The currency ladder continues at 50,000, 100,000, 500,000, and finally 1,000,000 dollars.
Spend your savings in the shop — buying 5 cars unlocks Mini Collection, and buying 10 unlocks Car Fleet.
All 70-plus cars are available through the shop.
You do not need to spend real money — every car and every badge can be reached with in-game currency alone.
