Rarity Factory Tycoon

Rarity Factory Tycoon is an RNG-based incremental tycoon on Roblox developed by RedNightBlade and the Rarity Factory Tycoon studio. Launched in September 2022 and running active seasonal events across three-plus years, it has earned a 92.2% approval rating and over 51 million visits - one of the most consistent approval records in its genre.

The factory produces orbs of varying rarities, and the entire game is built around improving how often rare orbs appear. The loop compounds through several interconnected systems:

• 💎 Orbs range from Common through Luminary, Zenith, and up to the coveted Secret rarity tier
• 💰 Process orbs through the factory to convert them into Money - rarer orbs yield exponentially more
• 💎 Droppers are the core investment - each dropper has a Luck stat that controls rare orb frequency
• 💎 Rebirth resets your factory for a permanent Luck multiplier that makes subsequent runs faster
• ⏳ Seasonal events run during Easter, Halloween, and Christmas with themed orbs and limited content
• 💎 Completing the on-map obby awards a free Speed Boost stackable with other active bonuses

Group members and Roblox Premium subscribers both receive a passive +1.1x Luck multiplier. Luck bonuses from droppers, group membership, and rebirths all stack multiplicatively, making the late game dramatically faster than early factory runs.

The closest comparison is Sol's RNG for RNG-driven progression, though Rarity Factory Tycoon structures that randomness through a tycoon build loop rather than open exploration.
