Progression route

Progression Route

The purchase order that keeps every run improving.

Updated

Shop panels with cars and cash bundles
Car Builds, Missing Parts, and the Exclusive Shop are the three shop tabs.

The shape of progression

Everything in the game converts into one of two things: better rolls or better runs. The mid-game is about alternating between them instead of dumping cash into one lane.

A healthy pattern from footage and shop prices: bank a run, buy the cheapest luck node available, bank another run, add the missing car part, repeat. Each lap makes the next one faster.

Priority order (with prices)

These are the observed prices, ordered by compounding value — the same order the tier list ranks.

When to stop grinding one lane

If every run ends at the same checkpoint, the fix is usually a part, not a skill. If every roll feels useless, the fix is a luck node, not a bigger car. Switching lanes when one stalls is the whole skill of the mid-game.

The Index is the decision tool: it shows which collection slots are still locked in each category, so you can target the category whose next unlock would most improve the car.

The five-figure stretch

Past roughly 10K cash decisions get expensive — the next meaningful upgrade usually costs thousands. By then runs should be reaching deep checkpoints regularly, and the question becomes whether distance or kills is the weaker earner for your build.

That is also the point where event currencies matter: Hacker Tokens from codes and events add alongside your cash income without competing for it.

FAQ

Progression Route FAQ

What is the single best early purchase?

Luck II at 250 — it is the cheapest permanent multiplier and it improves every roll from then on.

When should I buy my second support?

As soon as a second good roll arrives. Capacity upgrades like More Support II (3.70K) only pay off once you have pieces worth mounting.
