Sol's RNG is a Roblox rolling game where players repeatedly roll for auras of increasing rarity, and the rarest pulls are announced to the entire server so everyone can see who got lucky. A one-in-a-hundred-million result sits near the top of that rarity scale, which is why its announcement carries so much weight among players. Clips of the message are shared in gameplay videos, streams and short-form edits, often reused as a prank to make viewers believe an impossible roll has just happened.
