Free Custom Chess Puzzles — Build Your Own Tactics
Build your own chess puzzles for free. Set up any position on the board and turn it into a solvable puzzle — perfect for drilling one exact tactic, testing a pattern you just learned, or challenging a friend with a position you found. No signup, no daily limit, everything runs in your browser.
Unlike a fixed puzzle set, a custom puzzle is exactly the position you care about: a tricky fork you spotted in a book, an endgame idea you want to memorize, or a blunder from your own game you want to turn into practice. Set the pieces, pick the side to move, and solve it like any rated tactic.
Custom puzzles sit alongside rated puzzles, Crazy Puzzle rush and the repeat deck, so once you have built one you can fold it straight into your regular training routine.
What you can do with custom puzzles
Any position you want
Drag pieces onto the board or set up a specific arrangement, then turn it into a puzzle solvable move by move.
Practice a single tactic
Isolate one exact idea — a fork, a pin, a mating net — and drill it in isolation instead of waiting for it to show up in a random puzzle set.
Learn from your own games
Recreate a position from a game you played and turn the moment you missed into a puzzle you can solve properly.
Share a challenge
Set up a tricky position and challenge a friend to find the winning move, the same way you would pose a puzzle over the board.
Fits your regular training
Custom puzzles sit next to rated puzzles, Crazy Puzzle rush and the repeat deck, so they become part of the same training routine.
Free and private
Everything runs locally in your browser — no account needed, no cost, and no limit on how many custom puzzles you build.
How to build a custom chess puzzle
Set up the position
Drag pieces onto the board to build the exact position you want to turn into a puzzle.
Pick the side to move
Choose which side is to move, matching the tactic or idea you want to practise.
Solve it like a puzzle
Play the full line move by move — the tool checks each move the same way it checks a rated puzzle.
Reuse or reset
Solve it again, adjust the position, or set up a brand-new one whenever you want to drill something else.
