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.

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.Tournament View
Watch other matches unfold and discover who you’ll face next.Boss Fights
Face opponents that don’t just play better —
they play by different rules.
ARCHETYPES — DEFINE YOUR RUN
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 — STACK THE BROKEN
Bracelets are your main source of progression.
They:
Modify probabilities and outcomes
Reward specific playstyles
Create unexpected synergies
Stack into increasingly chaotic effects
Equip as many as you want —
and watch the game slowly lose its sanity.
CHEATS — FAIRNESS IS OPTIONAL
Yes.
Cheating is allowed.
Use cheat-like effects to escape bad situations, flip matches, or push your advantage even further.
But remember:
your opponents cheat too.
Especially the bosses.
BECOME THE UNDISPUTED JANKENPON MASTER
Start in shady taverns.
Climb through increasingly twisted tournaments.
Face opponents that challenge not just your luck — but your understanding of the rules.
Become the one contender who didn’t just master Rock–Paper–Scissors…
…but learned how to break it.
