Materials are buffs you roll at the spawn. Each roll costs more than the last and the published cap is 100,000,000 Cash. A playthrough put the first material unlock near 10,000 Cash. Modifiers from friends and from repeated runs are separate, and the page says modifiers stack.
Spin results
The chances below are printed one by one. Added together they pass 100 percent, so they are not a single pie. Frog is also locked behind a rebirth. Use the calculator only as an independent-spin estimate of the percent you type.
| Material | Published effect | Chance |
|---|---|---|
| Bronze | 1.1x multiplier | 16.5% |
| Silver | 1.25x multiplier | 16.5% |
| Brick | 1.5x, can crumble | 16.5% |
| Rubber | 1.1x bone value, very bouncy | 16.5% |
| Spark | 20% chance of a lightning break | 16% |
| Titanium | 1.5x bone value, harder to break | 7% |
| Glass | 8x bone value, breaks on hit | 6% |
| Explosive | Explode after 25 breaks | 6% |
| Frog | Frog jump after 5 breaks | 6%, rebirth required |
| Plant | +0.1x bone value when a bone breaks | 3.5% |
| Ghostglass | 5x bone value, breaks after 3 hits | 3% |
| Forge | +0.2x per ragdoll that has Forge | 3% |
The Forge diagram file name says +0.3x per ragdoll. The sentence on the page says +0.2x. Trust the number on the in-game tooltip if they differ.
Play videos also mention results such as magma that are not on this table. The materials page itself says it was still being updated. Those extra names are omitted here until an effect and a chance are published.
Run modifiers
| Modifier | How you get it | Effect |
|---|---|---|
| Friends | Friends in the same server | +10% each |
| Gold | 10 runs | 3x |
| Diamond | 40 runs | 8x |
| Void | 200 runs | 15x |
| Rebirth 2x | First rebirth | 2x |
Void is a run-count reward, not a spin material. A paid shortcut that turns Gold into every 5 runs was shown in a September 2025 video and is not given a current Robux price here.
How to choose
Glass is the largest printed multiplier and ends the bone on hit. Ghostglass is 5x for three hits. Forge and Plant grow with ragdolls or with break count. Bronze, Silver, and Rubber are common small bonuses. The tier list is an editorial sort of these tradeoffs, not an official rank.
