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.
