Break your Bones ☠️ Calculator

Two forms that use numbers you type. The spin form starts at Glass's published 6 percent. The payback form starts at Mutant's 800 Cash price and a fake 100 Cash sample you must replace.

This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own Break your Bones ☠️ session. It will not click the shop.

Drop probability

Material Spin hit chance

Estimates the chance of seeing a spin result at least once. Type the percent printed for that material. Glass is published at 6 percent, which is only the sample default. The published chances do not add up to 100 percent, and this form assumes independent spins. That may not be how the in-game wheel is coded.

Enter values from your session.

Chance of at least one success = 1 − (1 − chance per attempt) raised to the number of attempts.

Default 6 matches the published Glass chance. Replace it with the chance of the material you care about. Do not treat the result as an official drop rate.

Upgrade payback

Cash purchase payback

Compares a Cash purchase with the extra Cash you personally measure per run. The sample cost of 800 is the published Mutant price. The sample extra of 100 Cash per run is not a measured Mutant payout. Replace both numbers before you trust the result. Minute length is your own run time.

Enter values from your session.

Payback cycles = upgrade cost ÷ extra profit per cycle, rounded up.

800 is Mutant's published price so the form is not empty. 100 extra Cash and 1 minute are placeholders, not game data.

FAQ

Break your Bones ☠️ calculator questions

What do you actually do in Break your Bones?

Place a ragdoll on the conveyor or drop, let physics smash it through obstacles, and collect Cash from each broken bone. Spend Cash on bone levels, the next ragdoll, and Material Spin.

Does Break your Bones have codes?

No code box is documented for this experience. Use the conveyor, bone pads, Material Spin, and rebirth shrine instead.

What should a new player buy first?

Level bones your current ragdoll has, especially Skull and Rib Cage, and buy Mutant at 800 Cash when you can. The first Material Spin is about 10,000 Cash and gets more expensive.

How much is the first rebirth?

The published first rebirth is 25 billion Cash at the shrine beside the material stations. It grants a 2x modifier and three materials. The second is 25 quadrillion Cash for 4x.
