How do I start in Build A Cart?
Build or extend a cart train, buy the confirmed component families, drive for distance and cash, upgrade, and compare what your own run shows.
Which cart components are confirmed?
The official description names carts, engines, fuel, and turrets. It does not currently provide a complete named roster or stats.
How can I compare two cart runs?
Record the same fields for each run and use Cart Planner; it shows only ratios whose required entries are valid.
How do I go farther in Build A Cart?
Record one baseline run, change only one visible cart, engine, fuel, turret, or upgrade input, then repeat under similar conditions. Keep the change only when the displayed distance improves again; no universal farthest-cart build is confirmed.
What is confirmed about offline earnings?
The cart can keep driving and earning while you are offline. A rate, duration, and cap were not confirmed.
How do I rebirth in Build A Cart?
A current creator-owned source does not document the rebirth steps, requirements, reset effects, multiplier, or rewards. Check the live game before spending or resetting anything, and treat third-party thresholds as unconfirmed.
