Cases built for real solving
Each puzzle has its own title, story, categories, clue set, and solution. The goal is not to generate hundreds of thin variations, but to publish cases that are genuinely worth solving.
No account or progress tracking
The web puzzles are designed as a frictionless trial. They do not create a player profile or store coin, XP, puzzle progress, or completion history.
Progress from easy to hard
Start with easy cases to make X/O propagation automatic. Medium puzzles introduce more chained deductions; hard cases rely more heavily on indirect consequences and contradiction checks.
