RPS League

About

I started building a simple developer interview assignment 4 months ago and evolved it into a real-time prestige browser game called RPS League.The game resolves global matches every 5 seconds across all connected users using Server-Sent Events (SSE). Progression is driven by win streaks (3, 4, 5 wins trigger x2, x3, x5 multipliers) and a 40% random bonus system that can amplify rewards up to 7x or negate losses, scaling into BigInt ranges.A short showcase of visual events, seasonal tiers, and live-service systems:https://www.youtube.com/shorts/gEePdwCo-0YCore Systems:Ascension: At 999 Sextrigintillion (STR), players can reset for prestige progression or continue infinite ranking. Higher tiers permanently unlock visual styles that can be equipped at any time.Relic Locker: Collectible, duplicate-protected relics across five rarity tiers that modify gameplay.Global Events: Flash Events and Player Festivals dynamically alter gameplay and visuals across all users in real time.Idle Auto-Betting: Unlocks after the first lap, using the Page Visibility API to safely pause and resume state without desync.AI Oracle: In-game assistant connected to a systems knowledge base for mechanics, stats, and live guidance.No account. No install. Instant entry into a persistent live world.Play Now (No Signups): https://rpsleague.fi/Source Code (GitHub): https://github.com/AlexDegerman/rps-league-app/
