The one idea behind the Janken Deck
No suit is strongest.
Instead of red and black, the Janken Deck has five suits that beat each other in a circle. Tap a suit on the wheel to see what it beats — then try a real round.
- Rock
- Paper
- Scissors
- Water
- Lizard
The art
Every face card is real.
The faces aren't generic kings and queens. They're real rulers and legends from every corner of the world — researched, hand-illustrated, and printed bold enough to read at a glance.
- Xerxes of Persia
- Mansa Musa of Mali
- Nefertiti of Egypt
- Moctezuma II
- Kamehameha of Hawai‘i
- Qin Shi Huang of China
- Empress Myeongseong
- Sun Wukong

Storm Turtle Games turned two favorites — Janken Deck and King's Keys solitaire — into free mobile apps. A nice way to get a feel for the decks before you teach a friend.
About the maker
I'm Jeff — and I make cards that play differently.
"Each of my decks explores a new generation of card games by changing the structure of the deck. The Janken Deck swaps the suits for Rock, Paper, Scissors, Water and Lizard. King's Keys is a 4×4×4 deck with medieval themes. Dark Hand merges two 52-card decks, one light and one dark, into one. They're poker sized, printed in America on high-quality stock, and designed to be bold and easy to read for everyone."
— Jeff Daymont
