DeltaChess ♟️

Camping a rare spawn for the 47th time? Waiting for that one raid member who definitely won’t disconnect again (for real this time)? Standing around in Valdrakken doing absolutely nothing?

Support Development ❤️

If you enjoy DeltaChess and want to support its development (or just prevent the author from also camping rare spawns for gold), you can support my other WoW project blingtron.app — a Discord bot for raid leaders — on Patreon:

Support is completely optional, but very much appreciated.

Play chess. In WoW.

DeltaChess lets you play full, proper chess games directly inside World of Warcraft — against other players (yes, cross-realm) or against the computer — so you finally have something to do while the game refuses to respect your time.

What is DeltaChess?

DeltaChess is a lightweight but fully-featured chess addon for World of Warcraft. Open a board, challenge a friend, or start a single-player game and enjoy real chess rules without alt-tabbing, tab-crashing, or explaining to your raid why you’re suddenly AFK.

Challenge players by:

• Targeting them and typing /chess
• Using /chess PlayerName-RealmName
• Clicking the minimap button when boredom strikes

Yes, it’s real chess

No “WoW-flavored almost chess” nonsense here. DeltaChess supports:

• Castling (both sides)
• En passant (yes, really)
• Pawn promotion
• Check, checkmate, stalemate
• Fifty-move rule
• Insufficient material

Valid moves are highlighted, so you won’t embarrass yourself by trying to move a bishop like a warrior.

Play vs players or the computer

Not in the mood for humans?

• Single-player mode vs AI
• 4 built-in chess engines ranging from ~ELO 100 to 2600
• Pick an engine and difficulty directly from the UI
• Engines run fully async and are WoW-safe (no frame drops)

Included engines range from “Dumb Goblin” (greedy and very beatable) up to Fruit 2.1 for people who hate themselves.

Time pressure included (optional)

Want to simulate Mythic+ stress but with fewer repair bills?

• Optional chess clocks
• Configurable time per player (1–60 minutes)
• Optional increment per move
• Handicap clocks — give one side less time for uneven matchups
• Play as white, black, or let fate decide (just like raid loot)

Pause without the drama

• Pause any game — clocks stop, moves are blocked
• Human games require mutual agreement (no mid-checkmate stalling)
• AI games can be paused instantly
• Close the board vs AI and the game auto-pauses

Games don’t disappear (unlike your group)

• Games are saved automatically
• Disconnect? Crash? Rage quit? → Resume later
• Finished games are stored with full move history
• Track wins, losses, draws, and win rate
• Inactive games are automatically archived

PGN export

Played an immortal game between trash pulls?

• Export full games as PGN
• Standard algebraic notation with check markers
• Time control and clock annotations included
• One-click copy — paste into Lichess, Chess.com, or brag in guild chat

Features at a glance

• Play chess against other players cross-realm
• Single-player mode vs AI (ELO ~100–2600)
• Full standard chess rules implemented
• Optional clocks, increment, and handicap time
• Pause & resume games safely
• PGN export
• Saved & resumable games

DeltaChess is perfect for:

• Rare camping
• Raid downtime
• Queue waiting
• That moment when someone says “brb 2 min” and you know it’s a lie

Stop staring at your cooldowns. Start checkmating people. ♟️
