Build and Kill Zombies Parts: Roll Odds, Rarity & Prices
The five part categories
| Category | Machine | What it does |
|---|---|---|
| Blocks | CAR PARTS | The body of the car. Some blocks come in packs of five (the pad says x5). |
| Engines | CAR PARTS | Drive power. The tutorial has you roll and buy a Small Engine first. |
| Wheels | CAR PARTS | Carry the weight. Too heavy a car shows "Wheels straining under load!" before you set off. |
| Fuels | CAR PARTS | Fuel tanks. The gauge on the left of the speedometer drains as you drive and the run ends at 0%. |
| Supports | SUPPORTS | Weapons such as spikes, the Shredder and guns, placed from the Weapons tab of the build menu. |
How rolling works
- Walk up to the CAR PARTS machine. A Select Category window lets you tick Blocks, Engines, Wheels and Fuels; press CONFIRM.
- Roll. The part appears on one of the red pads with a label like Shredder, 1 in 4, Uncommon, $250.
- Buy it to keep it. Rolling itself did not take any Cash in the videos; the purchase does.
- The SUPPORTS machine next to it works the same way for weapons.
- Extra pads are locked behind a roll count ("In 20 Rolls") that ticks down every time you roll.
Luck improves what you roll. You can raise it with Cash on the skill tree (Luck I is +10%, Luck III +35%) or with Robux through the Luck passes and Server Luck in the shop.

Source: Roll pads shown in VendoPlus's How to Build Good Car video (uploaded September 12, 2026) and RobloMine's 1 to 14K meters playthrough (uploaded September 14, 2026). Odds and prices are copied from the pad labels exactly as shown.
Odds belong to the part, not to the rarity. The Rare Carbon Fiber Slab showed 1 in 20 while the Legendary Double Barrel showed 1 in 18, and the two Epic weapons were 1 in 8 and 1 in 12. Read the "1 in" number, not just the colour.
Parts seen without roll odds

| Passenger Seat | Seat | The MOREFRIENDS code gives two |
| Metal Spike | Weapon | In RobloMine's weapons tab (owned two) |
| Green Smasher | Weapon | In RobloMine's weapons tab |
| Hacker Bumper, Hacker Wheel, Hacker Fuel, Hacker Engine, Error Laser, Glitchy Turbo, Electro Glitch | Event parts | Hacker Event shop, 250 to 11,000 Hacker Tokens |
The Hacker parts are only sold for Hacker Tokens while the event lasts; prices for each are on the Hacker Event page.
Rarity tiers
The pads have shown 5 rarities, from lowest to highest: Common, Uncommon, Rare, Epic, Legendary. Sportskeeda's beginner guide also names Mythic and says there are more tiers above it. No Mythic part has come up on a pad in the videos used here.
Where the sources disagree
- Aprasi files the Glass Cylinder under the SUPPORTS machine. It comes in a pack of five for $15, which is how the block packs are sold, so its type is left as not confirmed.
- Aprasi says parts are rolled using cash. In VendoPlus's video the cash counter stayed at 210 across several rolls; money only left when a part was bought at the price on its pad (the tutorial Shredder took 300 down to 50).

Parts FAQ
How do I roll parts?
Walk to the CAR PARTS machine, pick a category (Blocks, Engines, Wheels or Fuels) in the Select Category window, confirm, and roll. The result appears on a pad with its name, odds, rarity and price. Weapons come from the SUPPORTS machine next to it.
Does rolling cost Cash?
Not in the recordings used here: the cash counter stayed the same across several rolls. You pay the price shown on the pad only when you buy the part, for example $250 for the Shredder.
What does x5 on a pad mean?
That roll gives five of the part. The Glass Cylinder (x5) pad sold five for $15 and the Carbon Fiber Slab (x5) pad sold five for $35.
What does "In 20 Rolls - LOCKED" mean?
More roll pads open as you roll. The signs next to the locked pads count down (20, 19, 17, 16 and 15 rolls were all seen), and the pad unlocks when the counter runs out.
What is the rarest part so far?
The Double Barrel, a Legendary weapon that showed 1 in 18 for $2.2K. Sportskeeda mentions a Mythic tier above Legendary, but no Mythic part has been shown on a pad yet.
Where can I see part stats?
In the INDEX menu (purple button on the left). It lists the parts you have unlocked by category. Speed and damage numbers per part have not been published anywhere else yet.
