ChessFlex is chess stripped back to the game. No accounts, no servers, no chat — just the board, the friends you choose, and a real rating that's yours. PLAY YOUR CIRCLE Connect by trading a QR code, in person or over iMessage. No global matchmaking, no strangers, no friend requests. The people across the board are people you picked. HUMANS — OR HUMAN-LIKE BOTS Five built-in bots from 400 to 2000 ELO play like real people at that level: they make human mistakes, not random ones. A real game and a real rating from your very first move. And when you've beaten them all, there's King — our own engine at full strength, and not human-like at all. FIDE-FORMULA RATING Every game updates your rating with the standard FIDE formula. It's your history, not your ceiling — anyone can challenge anyone, and a 1200 taking on a 2000 is courage, not a mistake. PLAY AT YOUR PACE Async by default — make a move, put your phone away, pick it up hours later. Or set a clock: Blitz, Rapid, Classical, or multi-day correspondence. THE BOARD IS THE CONVERSATION There's no chat box, ever. Players speak only in standard chess annotation symbols — !! for a brilliant move, ? for a mistake. Nothing personal can be exchanged, so there's nothing to moderate, and it's cross-language by default. PRIVATE BY DESIGN No email, no sign-up, no tracking, no ads. Your identity is your device; your games live on your device and travel only between you and your opponent. CHESSFLEX STUDY (optional) A one-time unlock that turns every game into a lesson: move-by-move analysis, win-chance insight in plain language, guided openings, and practice positions. Scan a chess diagram from a screenshot and play it out, or have the coach read its suggested line aloud. Playing, ratings, and opening names stay free, always. From Labham LLC. A sibling to LexFlex.

This is not the chess you know. Dark Squares is chess, unhinged: every piece can wield a weapon. All the strategy of chess, none of its mercy. FREEZE the knight charging at you. TELEPORT your queen across the board. BLIGHT the enemy ranks and watch them wither. ASCEND a humble pawn into royalty. And when the path is open — take the king. HOW IT PLAYS • Real chess at the core: every classic move works, every classic plan matters. • Weapons change everything: arm a loadout of spells before each battle and cast them at the perfect moment. • Win by capture: no checkmate formalities — the game ends when a king falls. MODES • Play a Friend: challenge friends directly to friendly duels — and earn XP while you're at it. • Play vs Computer: three difficulty levels, and yes — the computer casts weapons too. • Open arena: bring your full loadout against anyone online. • Normalized arena: a fair, ranked duel — both players draft from the same weapon pool, so skill alone decides it. PROGRESSION • Earn XP in every online game — win or lose. • Unlock new weapons and upgrade them to higher tiers as you climb the ladder. • Build your Armory and craft the loadout that fits your style. DARK SQUARES PRO • An optional subscription ($4.99/month, auto-renews) that instantly adds four more weapon families — Aegis, Silence, Blight and Oracle. • Pro is variety, never raw power — free weapons stay fully competitive. Dark Squares is young and evolving — your feedback shapes what comes next. Every piece, a weapon. Every move, a gambit. Welcome to Dark Squares.
