Load The Truck luck affects multiplier goals, but exact odds stay source-pending.
Increase luck when you are already moving boxes into trucks reliably and want better box or truck multiplier outcomes. If carrying, worker coverage, or cash flow is still weak, fix that bottleneck first. The official Roblox page names luck and multipliers, but it does not publish odds, caps, prices, or formulas.
