Generate a puzzle.
Multi-size, real difficulty.
Every puzzle is guaranteed to have exactly one solution, with difficulty that reflects real solving techniques — not just the number of blanks. Generate batch after batch for KDP sudoku books, brain-training packets for seniors, or daily logic warm-ups for the classroom, each with its solution grid.
Like every PuzzForge generator, it exports clean A4 print-ready PDF (plus PNG and JPG) and is free to start — no credit card required. Explore the other printable generators, browse ready-made templates, or see what Premium adds: watermark-free and SVG export, advanced styling, your own logo and unlimited cloud projects.
