Aura Farm: RNG is a luck game about rolling auras. Press Roll and you get a random aura. Most rolls give a Spark or some Dust, but somewhere among the 65 auras sits the Primordial, at 1 in 100,000,000.

The rarer the aura, the more it shows on your character: flames, lightning, wings, glitches, cosmic effects.

What else is in there:

• Day and night: moon auras drop far more often at night
• World events: Starfall, Storm, Northern Lights and the rare Glitch boost your luck
• The Wilds outside the gates: monsters, hidden chests and 4 bosses with auras of their own
• Three daily quests and weekly challenges
• Luck potions and gloves crafted from materials found around the map
• Auto-roll and offline progress: the game keeps rolling while you're away
