Janken (じゃんけん) is Japanese rock-paper-scissors. A cultural institution—used everywhere from playgrounds to boardrooms for making quick, fair decisions.
Beats Scissors
Beats Rock
Beats Paper
The simplicity of rock-paper-scissors meets the rigor of cryptographic fairness.
Commit-reveal protocol locks in your move before anyone reveals. No house can cheat, no opponent can peek.
Every commitment, reveal, and settlement is recorded on Solana. Transparent and auditable.
Every settled match burns 10% of the pot. The more you play, the scarcer $JKN becomes.
No house edge. No hidden tricks. Just you vs another player in symmetric competition.
Track win streaks, biggest pots, and climb the global ranks. Flex your dominance.
Everyone knows rock-paper-scissors. Jump in and start dueling in seconds.
Four simple steps. Provably fair. No bullshit.
Get $JKN tokens
Link wallet, choose stake, enter lobby
Lock in your move, then both reveal
Winner takes 90%, 10% burns forever
No house edge.
Burns benefit all $JKN holders equally. The protocol takes nothing—supply reduction is symmetric across all participants.
Tie? Pot returns to both players. No burn.
"The game is the sink. The sink is the story."
How It Works
Every settled match burns 10% of the pot. The more people play, the scarcer $JKN becomes. Deflation is endogenous—driven by actual gameplay, not arbitrary schedules.
The Flywheel
More games → More burns → Less supply
Less supply → Higher scarcity → More attention
More attention → More games... 🔁
Scissors cut paper. Burns cut supply.
