Janken Deck

Welcome to!

What is the Janken Deck?

The Janken Deck combines Rock Paper Scissors rules with a classic playing card format for a new way to play cards!

Rock, Paper, Scissors, Water and Lizard make up the five suits. Each suit has different strengths and weaknesses against each other but no suit is strongest. Each suit has the familiar Ace through Ten, Jack, Queen and King. There is even a Joker in every suit for the more challenging games! is your source for game rules and updates. Be sure to bookmark this site and then connect on social media for the latest updates and new game rules!

The second print for the Janken deck with new purple backs will also be coming in spring.

Play Games!

The Janken Deck gives you lots of ways to play. Take out the Water and Lizard suits for easier games or combine the whole deck with a standard deck to play with nine suits at once! Some games depend on the Rock-Paper-Scissors rules, some games are just more fun to play with five suits instead of four.

Like Puzzles?

Rock-Paper-Scissors logic opens a new world of puzzles. Sometimes the simplest rules can lead to unexpected challenges!

I've created a few puzzles using the Janken Deck here. Perhaps you'll discover more of your own as you play!
