What is Monster Coup?

Two secret cards, a few coins, and as many lies as you dare. 2-6 players.
If you have played Coup, you already know the idea: Monster Coup is inspired by it and adapted to play online, everyone on their own phone, with bots for missing players.
Coup is a trademark of its publisher. Apateon is not affiliated with or endorsed by it.

How to play Monster Coup

  • 1
    You hold two secret monsters. Each one has a power — the Dragon taxes, the Shade kills, the Kraken steals.
  • 2
    On your turn claim any monster to use its power, whether you hold it or not. Anyone can call your bluff; the loser of a challenge loses a card.
  • 3
    Some powers can be blocked by claiming the right card. Lose both cards and you are out — the last one standing wins.

Full Monster Coup rules

The goal

  • •
    Everyone starts with two hidden monster cards (their influence) and two coins.
  • •
    Lose a challenge, get assassinated or suffer a coup and you turn a card face up. With both face up you are out. Last one standing wins.

Anyone can do these

  • •
    Income: take 1 coin. Nobody can stop it.
  • •
    Foreign aid: take 2 coins. Anyone claiming the Dragon can block it.
  • •
    Coup: pay 7 coins and make a player lose a card. It cannot be blocked. With 10 or more coins you must coup.

Challenges

  • •
    Whenever someone claims a monster — to act or to block — anyone may challenge.
  • •
    If they really hold it, they show it, shuffle it back, draw a new one, and the challenger loses a card.
  • •
    If they were bluffing, they lose a card and the action (or the block) fails.
  • •
    You have a few seconds to answer; staying quiet means you let it happen.

Tips to win at Monster Coup

  • •
    Claiming the Dragon to collect 3 coins is the most common early lie: few players risk challenging it on the first turn.
  • •
    Count the revealed cards: there are three copies of each monster. If two Gorgons are already face up, whoever claims the third is probably lying.
  • •
    A Coup costs 7 coins and cannot be blocked or challenged: save it for the most dangerous rival at the table.
  • •
    With one card left, think twice before challenging: if you are wrong, you lose your last card and you are out.
  • •
    If someone tries to assassinate you and you have one card left, claiming the Gorgon almost always pays: without the block you would lose it anyway.
