About

RNG Simulator is an application that allows you to play with different monster's drop rates. It uses a simple algorithm that takes in a list of items with weighted values and generates a random number, resulting in a "random" item drop.
The rarity of items per monster replicates the exact rarity from Old School RuneScape.
All drop table data is fetched via the osrsbox API.
All images of monsters are from the oldschoolrunescape.wiki

If you really like this for some reason and feel the urge to buy me a nice cuppa tea, my unemployed self would very much appreciate it or if you need any digital marketing services hit us up at UntitledOne | Digital Marketing Agency.

Future Development

- Drop rates for things like clue scrolls and raids as well as the "Rare and Gem drop tables" and Pets will be added in the future.
- Grand exchange prices & total loot value will be added in the future.
- Item drops that currently contain a range in quantity will instead select a random quantity within the range.

Limitations:

Currently, the application does not take into account the "Rare and Gem drop table" or drops that should be multi-rolls. This will be addressed eventually.
Certain drops display a range in quantity, this may lead to undesired calculations.
