You reach an endgame a pawn up and the win slips away. Chessbrix is built to fix exactly that. 384 positions across 33 chapters take you from mating with a lone rook to the rook and pawn endings that decide master games. Every chapter opens with guided lessons that walk you through the plan move by move, then gives you positions to practise it on. WHAT YOU GET • 384 endgame positions across 33 progressive chapters • 192 move-by-move lessons that explain the idea before asking for the move • Basic mates, pawn, rook, bishop, knight and queen endings • Spaced repetition brings back the positions you got wrong, until they stick • A daily challenge and a streak to keep you coming back • Hints with on-board arrows when a position will not give • Play any position out against the engine to see why the plan works • An analysis board with undo, redo and PGN export • Notes you can attach to any position • Progress tracked per chapter, so you can see what is still weak START FREE The beginner chapter is completely free: 36 positions on checkmating a lone king, with no time limit and no account. Work through it before deciding whether the rest is for you. BUILT FOR IMPROVEMENT Positions are graded from under 1000 to roughly 2300 Elo and grouped by concept, so you can start where you actually are. Nothing here is filler. Every solution is checked against a chess engine and an endgame tablebase before it ships, so the answer you are shown is the right one. NO ACCOUNT, NO TRACKING Chessbrix works entirely offline.
