UNI vs. UNO (what's similar)

  • Match cards by colour or number
  • Familiar action cards (Skip, Reverse, Draw Two)
  • Round ends when your hand is empty

What's different (The Hook)

  • Crazy UNI-specific cards and chaotic mechanics
  • Build and create your own deck to play with friends
  • Play with your favorite custom rules

"It feels as if someone played modded Minecraft or Risk of Rain 2, and chugged down all of the mods existing."
