Take chess to the next level by moving any piece you'd like out-of-turn! In this RTS-style chess game, each chess piece has its own "cool down time". You can move each piece every 5 seconds—even if your opponent doesn't make a move! Play free chess online with your friends or with strangers! Singleplayer is great for beginners and experts! I modified an open-source chess AI engine called Garbo-Chess giving even trained chess players a challenge. Kill the King Features: - Queens, rooks and all pieces can move out-of-turn - Extremely difficulty singleplayer AI - Play free multiplayer chess with friends - AI uses a modified, real chess AI engine - Chess becomes a frantic, 1-on-1 army battle If you have any feature that you'd like added, do not hesitate to email me!

Chess with one capture rule changed — and that one change rewires how you think. THE RULE Pieces can only capture the same type. • Pawns capture pawns • Knights capture knights • Queens capture queens • Kings still capture anything (like normal chess) Everything else is normal: check, checkmate, castling, en passant, promotion. WHY PLAY THIS Regular chess rewards muscle memory. Openings on autopilot. Patterns you stop questioning. Here, every capture is a decision. Positions that look like blunders aren’t. Safe-looking pieces suddenly aren’t. It’s a workout for calculation — the kind that transfers back when you return to standard chess. FEATURES • Full games vs CPU (multiple strengths) or pass-and-play • Offline — no account required • Weird-rule mate puzzles built for this capture rule • Themes and piece sets • Optional clocks If you’re stuck in the same games, try a rule that won’t let your hands play for you.

Verdict
The clearest difference is ads: Kill the King at none against Chess's shown. Kill the King also leads on update cadence (daily vs every 5 days) and iOS requirement (8.0 vs 17.0). On price, in-app purchases and device support there is nothing between them.
