Official Unstable Unicorns Rules

Unstable Unicorns is a strategic card game with a delightful dash of chaos, where you build a stable of unicorns and use special cards to hinder your opponents! Here's a breakdown of the rules:


Be the first player to collect a specific number of unicorns in your stable (usually 7 unicorns). You'll achieve this by acquiring unicorn cards and using magic cards to your advantage, while strategically hindering your opponents' progress.

Number of Players: 2-8 players (more players require purchasing additional decks)


  • Deck of Unicorn Cards (contains basic unicorns and special unicorns)

  • Deck of Magic Cards (contains instant, upgrade, and downgrade cards)

  • Stable mats (optional)

  • Neigh cards (optional, used to negate certain card effects)


1. Shuffle the deck of unicorn cards and deal each player a hand of five cards.

2. Place the remaining unicorn cards in a draw pile in the center of the table.

3. Separate the baby unicorn cards from the rest of the deck and place them in a separate draw pile.

4. Each player chooses a basic unicorn card and places it in front of them to start their stable.


1. Turn Structure:

  • On your turn, you can perform one of the following actions:

    • Draw a card: Draw one card from the draw pile.

    • Play a card: Play a unicorn card or a magical card from your hand.

    • Use a card's effect: Some cards have effects that can be activated during your turn. 

2. Building Your Stable:

  • To build your stable, you need to play unicorn cards from your hand into your stable in front of you.

  • You can only have one basic unicorn in your stable at a time, but you can have any number of magical unicorns.

  • Some unicorn cards have effects or ongoing abilities that affect gameplay. 

3. Magical Cards:

  • Magical cards have various effects and can be played to help you or hinder your opponents.

  • Some magical cards allow you to steal unicorns from other players' stables, destroy their unicorns, or protect your own unicorns from sabotage. 

4. Baby Unicorns:

  • Baby unicorn cards can be collected by playing cards with the "baby unicorn" effect.

  • Collecting baby unicorn cards contributes to your overall unicorn count, making it easier to win the game.

Winning the Game

  • The first player to successfully have a certain number of unicorns in their stable wins the game. This number can vary depending on the agreed-upon game length or the number of players.


1. Rainbow Apocalypse Mode:

  • This mode introduces a new "Apocalypse" card to the deck. When drawn, the Apocalypse card triggers the end of the game immediately, and the player with the most unicorns in their stable wins.

  • This mode adds a sense of urgency and unpredictability to the game, as players must race to build their stable before the game abruptly ends.  

2. NSFW Expansion:

  • The NSFW (Not Safe For Work) expansion introduces a new set of unicorn and magical cards with mature themes and humor.

  • This expansion is intended for adult players and adds a more risqué and irreverent element to the game.  

3. Unicorns of Legend Expansion:

  • This expansion introduces legendary unicorn cards with powerful abilities that can significantly impact gameplay.

  • Legendary unicorn cards provide new strategic options and add depth to the game as players strive to collect and utilize these powerful creatures.  

4. Control and Chaos Mode:

  • In this mode, players can choose between playing with the "Control" deck or the "Chaos" deck.

  • The Control deck contains cards that provide strategic advantages and opportunities for long-term planning.

  • The Chaos deck contains cards that introduce random events and chaotic effects, adding an element of unpredictability to the game.  

5. R-Rated Mode:

  • Similar to the NSFW expansion, R-Rated mode introduces a set of unicorn and magical cards with mature themes and content.

  • This mode is intended for adult players and features more explicit and graphic content than the standard game.  

6. Rainbow Sprinkles Expansion:

  • This expansion adds new rainbow unicorn cards with unique abilities that can influence gameplay in various ways.

  • Rainbow unicorn cards introduce new strategic considerations and add variety to the game as players compete to collect and utilize these special unicorns.

That's the basic gameplay of "Unstable Unicorns"! It's a whimsical and strategic card game that combines elements of set collection, hand management, and player interaction.
