Turn calculation into instinct.

PuzzleForge is a premium offline chess tactics trainer and chess training app designed for serious chess players seeking rapid improvement. Featuring a massive database of 40,000+ curated chess puzzles, custom Woodpecker Method drill sets, and endless tactical training, it uses spaced repetition to develop the pattern recognition and calculation speed that win games.

No cluttered menus. No online matchmaking. No distractions. Just you, the board, and the puzzles.

THE WOODPECKER METHOD
PuzzleForge is built around spaced repetition: solve the same tactical puzzles over and over until the geometry of the board becomes second nature, your calculation speeds up, and you recognize winning patterns on sight. Woodpecker Mode puts the method in your hands — build personalized chess puzzle sets of 50, 100, or 200 tactics, then drill them across multiple runs while tracking your accuracy and completion time. Watch your solve times drop with every cycle as you build the exact chess training routine you need to level up your Elo.

THE BURN BOOK
The puzzles you miss are the ones you need most. PuzzleForge automatically tracks every tactic you get wrong and stores it in the Burn Book — a dedicated review mode that forces you to confront and conquer the specific blind spots costing you games.

ENDLESS MODE
Dive into a true endless mode powered by 40,000+ chess tactics puzzles. Stack and combine motifs to filter ultra-specific puzzle streams and attack your weak spots head-on. Want to practice sacrifices that lead to knight forks? Need puzzles built around pins and mating attacks? Layer the themes you choose, patch the holes in your calculation, and forge razor-sharp board vision.

100% OFFLINE
Train on a plane, on the subway, or during a night shift with zero signal. PuzzleForge's entire puzzle database and evaluation engine run completely offline, directly on your device.

CLEAN, PREMIUM UI
A gorgeous, distraction-free interface with custom board colors, transparent move indicators, and an elegant design that feels like a high-end desktop client right in your pocket.
