Hue Chess 作者： prefabcode

Hue Chess is a gamification mod for lichess that adds experience points, levels, and unlockable perks to lichess.

The basic premise is that when you win games on lichess, you earn "hue points" which increase your experience within a level and change your chess board color. There are 100 hue points in one level, and there are 15 levels in total. When you accumulate 100 hue points in a level, you "level up" and move on to the next chess-board theme.

In addition, Hue Chess features selectable perks that you unlock as you level up. Perks act as a bonus modifier on the amount of hue points you earn for winning games on lichess. As an example, you start with a perk called "Opportunist". When selected, Opportunist grants extra hue points per win on lichess, if you are up in material for more than one move at any time in a chess game. You may only have two perks selected at any given time.

Hue Chess features 12 unlockable perks, spread across 15 levels. It also features a prestige system.

The extension is 100% free and the source code is open for anyone to use anyway they like.
