About this activity
These compact puzzles are practice activities, with a deliberately small board or sequence. They are not a complete catalogue of tournament puzzles. There is no timer or competitive ranking. Correct-answer counts describe this task only.
Some puzzles can have more than one valid solution; grid checks accept any solution that meets the displayed constraints. Hints follow a known example solution. Familiarity, hints and previous attempts affect performance.
