About Perk Chess

Perk Chess is a Chrome extension that brings Call of Duty–inspired gamification to Lichess. Win games, earn XP, level up, unlock perks, and climb the prestige ranks. It's a whole progression layer on top of the chess you already play. Every win earns XP Points, which nudge your board color and push you toward the next level. Each level takes 100 XP and comes with its own board theme, across 15 distinct levels to complete the Perk Chess Challenge. The Perk System is the heart of it. Perks reward you with bonus XP for pulling off specific feats in your games, and you unlock new ones as you level up. You run two at a time, so you build a loadout that fits how you play. Features: XP & Levels: Win games to earn XP and progress through 15 levels, each with its own board theme. Perk System: Unlock 12 perks as you level up, each offering a different way to earn bonus XP. Equip two at once to match your playstyle. Specializations: Beat all 15 levels to unlock RPG-style classes that reshape your perk unlock order around a theme (Gladiator, Gambiteer, Berserker, and more). Prestige: Finish the game and prestige, climbing the ranks with a new emblem to show for it. Time-Based Rewards: Slower time controls award more XP than faster ones. Progress Tracking: A progress bar shows your current level and how close you are to the next. Easter Eggs: A few surprises tucked away for you to find. Purely cosmetic. No move suggestions, no analysis, no assistance of any kind. Just a more fun reason to keep playing. Perk Chess is open source: https://github.com/prefabcode/perk-chess Perk Chess 2.0.4 release notes: - Hypermodern perk now triggers after 4 moves instead of 5. - Fixed bugs with some glyphs not rendering properly
