Why it exists
Games often show a very small per-attempt drop rate but do not make the cumulative probability intuitive. This project combines a lightweight manual counter with calculators that explain what repeated independent attempts mean.
How the tools are built
The counter saves its total in local browser storage. The probability tools use the standard independent-events formula and expose the rate, multiplier, attempt count, and target percentage as editable inputs. Results are estimates and never guarantees.
Editorial principles
- Separate confirmed facts from editable planning assumptions.
- Link to primary sources when discussing a live event.
- Avoid official logos, copied artwork, cheats, account access, or game-process access.
- Correct material errors and update time-sensitive rate notes.
