Chess was built for two. This is chess for FOUR. 4-Player Chess is the chaotic, four-army take on the game you know โ€” played free-for-all on a giant 14x14 cut-corner board. Four kings, three rivals, one winner. Capture pieces to bank points, hunt checkmates for big bonuses, betray, kingmake, and steal the win on points while the two leaders slug it out. Real chess credibility, total party chaos. WAYS TO PLAY - Play vs. Bots โ€” three difficulty tiers (Easy, Medium, Hard) and original characters with personalities of their own: Turbo the laid-back turtle, Fang the dramatic wolf, and Nova the hyper-precise robot. They talk, they react, and they taunt you when they corner your king. - Pass & Play โ€” hand one device around the table. Free-for-All or Teams 2v2. - Online Multiplayer โ€” jump into Quick Match, or spin up a private room and share a code with friends. Finished Quick Matches move your ELO rating. - Live or Daily pace โ€” play a fast game now, or run up to ten correspondence games at once at one move per day. The My Games hub shows YOUR TURN at a glance, so 4-player chess becomes a habit you check, not an event you schedule. DAILY PUZZLE A fresh four-player mate-in-1 every day, the same one for everyone. Solve it, keep your streak alive, and share the result. THE UNDYING KING A limited-time event boss whose king refuses to die โ€” even his fallen army keeps a monarch on the move. Can you finally mate the immortal?
