Basic Match Format
All official competitions in RPS Online use the same fundamental match format:
First to 3 Wins (Best of 5)
- • Players compete in individual rounds
- • Each round: simultaneous Rock, Paper, or Scissors throw
- • First player to win 3 rounds wins the match
- • Draws don't count — the round is replayed
- • Maximum possible rounds: 5 (2-2 going to decisive round)
This format ensures matches are meaningful while remaining quick enough for daily play. A skilled player can complete a match in 2-5 minutes.
Janken Pro League (JPL)
じゃんけんプロリーグ
The JPL is our flagship seasonal competition, modeled after professional football leagues. It features multiple tiers with promotion and relegation.
Season Structure
14 days per season
2 per player (attack + defend)
+3 points
+0 points
Tier System
The JPL features multiple tiers (Pro League 1, Pro League 2, etc.). Players are divided based on skill level.
Attack vs. Defend Games
Each day, you play two matches against different opponents:
- ⚔️Attack Game: You are the designated attacker. Win to prove aggressive capability.
- 🛡️Defend Game: You are the designated defender. Win to prove defensive resilience.
Home vs. Away
The schedule also designates Home and Away games. These designations may affect certain situational bonuses and add variety to the season. Home games give a slight psychological advantage — just like in real sports.
RPS Ladder (RPSL)
ラダーランキング
The RPSL is a "King of the Hill" style competition where you challenge players ranked above you and defend against challengers from below.
How It Works
- Challenge: Once per day, challenge someone ranked 1-3 positions above you
- Win: Take their position (they drop down one spot)
- Lose: Stay at your current position
- Defense: You must defend against challenges from below
Ladder Strategy
Rising through the ladder requires both winning your challenges AND defending your position. A player who climbs quickly but can't defend will yo-yo up and down.
Climbing Tips
- • Challenge daily — don't waste opportunities
- • Study opponents before challenging
- • Time challenges strategically
Defense Tips
- • Maintain unpredictable patterns
- • Don't underestimate challengers
- • Stay mentally fresh for defenses
RPS World Series (RPSWS)
ワールドシリーズ
The RPSWS is a knockout tournament format, similar to tennis Grand Slams or World Cup brackets. It's high-stakes, elimination-style competition.
Tournament Format
- Seeding: Players seeded based on JWR ranking
- Byes: Top seeds may receive first-round byes
- Single Elimination: Lose and you're out
- Round Deadlines: Each round has a deadline to complete
Tournament Stages
Janken World Ranking (JWR)
世界ランキング
The JWR is a global ranking system that tracks player performance across all competitions. Think of it like tennis ATP rankings — your overall standing in the competitive RPS world.
How Points Work
- Wins earn points: Amount varies by opponent strength and competition type
- Losses cost points: Losing to lower-ranked players hurts more
- Giant kills: Bonus points for beating much higher-ranked opponents
- Comebacks: Bonus for winning from 0-2 down
Ranking Benefits
Your JWR ranking affects several things:
- •Tournament seeding: Higher ranked = better seeds in RPSWS
- •League placement: Affects your starting tier in new JPL seasons
- •Prestige: Leaderboard recognition and bragging rights
