WELCOME! TO! THE! JANKENPON! HISTORY!!!
jankenpon is a fast-paced roguelike Rock–Paper–Scissors tournament where luck is optional, cheating is encouraged, and the rules are made to be bent.
Win matches, stack damage, buy upgrades, and survive a tournament that evolves run after run.
A TOURNAMENT-DRIVEN ROGUELIKE
Each run follows a simple but ruthless loop:
Match
Win rounds of Rock–Paper–Scissors to deal damage.
Stack hits until one fighter’s HP reaches zero.

Shop
Spend your winnings on bracelets that twist probabilities, outcomes, and core rules.

Map
Pick your own path on the map. Make a stop at the shop, train your moves, or battle enemies. Only one goal... get to the boss and show him what you are made of !

Boss Fights
You are looking for a real challenge ? Boss Fights are just what you need. They are tougher and can switch their strategies during the match.

ARCHETYPES
At the start of a run, choose an Archetype.
Archetypes are powerful, cheat-like modifiers that influence how the game behaves:
How information is revealed

How much control you have over outcomes

How you mitigate randomness

How you take risks

They don’t dictate a single strategy, they shape the entire run and push you toward different builds and decisions.
BRACELETS
Bracelets are your main source of progression.
They:
Modify probabilities and outcomes

Reward specific playstyles

Create unexpected synergies

Stack into increasingly chaotic effects

You have a limited number of slots, so choose carefully !
CHEATS (IT IS REALLY ALLOWED)
Yes.
Cheating is allowed.
Use special effects to escape bad situations, flip matches, or push your advantage even further.
But be careful:
your opponents cheat too.
Especially the bosses.
BECOME THE ULTIMATE JANKENPON MASTER
Start at the bottom of the ladder.
Climb through increasingly twisted tournaments.
Face opponents that challenge your understanding of the rules, and how you adapt to them.
Become the one contender who didn’t just master Rock–Paper–Scissors…
…but learned how to break it.
