Rogue-TS

Play Now | Daily Challenge

A faithful TypeScript port of the classic Rogue (1980) dungeon crawler, playable directly in your browser. Every monster stat, item property, dungeon generation algorithm, and game mechanic preserved from the original C source. The only change is the platform: curses replaced with HTML5 Canvas.

Features

Everything from the original Rogue, running natively in the browser:

• 26 monster types (A-Z) with exact original stats, behaviors, and special attacks
• 14 potions, 18 scrolls, 9 weapons, 8 armors, 14 rings, 14 wands — all with original effects
• Procedural dungeon generation — 3x3 room grid with corridors, dark rooms, mazes, and treasure rooms
• 8 trap types — teleport, arrow, sleep, bear, pit, dart, rust, mysterious
• Full combat system — attack rolls, damage dice, armor class, strength bonuses, experience levels
• Hunger system — find and eat food or starve
• Item identification — colored potions, titled scrolls, gems on rings, wood/metal wands
• Fog of war — rooms light up when entered, corridors reveal as you explore
• Daemon/fuse system — timed effects for confusion, haste, blindness, hallucination
• Amulet of Yendor — descend to level 26+, find it, and escape back to the surface to win
• Seedable RNG — share runs via URL, compete on daily challenges
