How to Use This Calculator

Use a probability that matches the exact cube, region, potential tier and desired outcome. Enter 1 for a 1% chance, not 0.01.

Formula & Methodology

The probability of no success after n independent attempts is (1 − p)^n. Therefore, the probability of at least one success is 1 − (1 − p)^n. Expected successes equal n × p.

Example: 100 attempts at a 1% success rate

With a 1% chance per independent attempt, 100 attempts have about a 63.4% chance of producing at least one success. This does not guarantee a success.

Results are planning estimates. Game mechanics, rates, caps, regional versions, servers, seasons and event rules can change.

Frequently Asked Questions

Does the expected number of cubes guarantee success?
No. It is a long-run average. Any individual cubing session can finish earlier or take much longer.
Can I use official or community cube rates?
Yes, but use a rate that matches your region, cube type, current potential tier and exact target outcome.
Why does 100 attempts at 1% not equal a 100% chance?
Each attempt can fail. The correct cumulative probability is 1 minus the probability that every attempt fails.
