A probability form for a 1-in-N mount you convert to a percent. It does not know your Luck.

This calculator is arithmetic on a table, not a live mixer. Enter quantities from your own [🎃] MOUNT RNG session. It will not click the shop.

Drop probability

Roll odds helper

Estimate the chance of seeing a listed mount at least once. Enter the percent yourself from the in-game 1-in-N index. The default is only the documented 1-in-6 starter example, not a rare-mount rate, and the form does not apply Luck.

Enter values from your session.

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

16.67% matches a published 1-in-6 example such as Roblox Noob. If the mount index says 1 in N, enter 100 divided by N. Luck potions, friends, and passes are not folded into this result. Identical potions do not stack their Luck numbers; this form also cannot model that.

FAQ

[🎃] MOUNT RNG calculator questions

What is MOUNT RNG?

MOUNT RNG is a Roblox incremental simulator by TaleSun Studios. You roll for more than 700 mounts, sell duplicates for Essence, unlock islands, and fight beasts. Version 1.54, Update 54, is the Halloween update described on the official page.

How do I raise Luck without Robux?

Like the game, join the TaleSun Studios group, and turn on notifications for +20 Luck. Each friend in your 12-player server adds +5 Luck, and those bonuses stack. Free ground potions add +50 Luck for one minute. Buy Ultra Luck only after that free stack is on.

Which codes should I try first?

Try CORTISOL, FORTNIGHT, LESSON5, SIGH, and 2YEARS first. Mid-October 2026 lists repeat those more often than the rest. The other active rows are still printed by at least one October list and marked expired by another, so enter each one once and stop if it fails. The live version 1.54 description does not print code strings.

How many official badges are there?

The Roblox catalog for this experience lists seven badges: Welcome to Mount RNG, Auntum Fields, Paradise Island, Frozen Reach, Celestial Peak, The Magma Lair, and Against the Test of Time for obtaining Azatoth on the secret island.
