From your inputs to a usable result
01
Choose a focused puzzle booklet
Pick from eighty original boards in eight types, with up to twenty boards per booklet. Use Starter or Step-up as board groupings, not age or ability ratings.
02
Try, check and explore
Solve on screen, check recorded attempts and reveal an answer key when needed. Eight deterministic variations change orientation, order or symbols while keeping the rules.
03
Print separate questions and keys
Export worksheet or answer-key PDF, PNG or SVG pages with existing print fonts. CSV records answers and attempts; JSON preserves the exact boards and project.
Before you start
Where is my project saved?
Projects are saved in this browser for this site account. Download a JSON backup before changing devices or clearing browser storage.
Which puzzle types are included?
Mini Sudoku, consecutive number paths, mazes, word search, mirror grids, explicit repeating loops, shape counting and missing-number equations. Each type has ten original board sets. Existing FE bingo, pairs and dominoes remain separate.
Are the answer keys checked?
Sudoku and number-path clues must determine one solution; each listed word has one placement. Maze passages form a connected tree with one route between endpoints. Reflection, loop, count and equation answers follow their explicit rules.
Do variations make unlimited new boards?
No. Each board offers eight deterministic orientations, orderings or shape-label changes. Symmetric details may repeat. Changing variation clears that board’s attempt; Undo can recover it.
Do worksheets include my answers?
No. Worksheets contain clues and empty answer spaces. Answer keys are separate exports. CSV and JSON retain recorded attempts. Planning notes are printed on separate note pages.
Does the check assess learning ability?
No. It checks the supplied puzzle answers only. Board grouping labels are not validated age, developmental or ability measures. Attempts stay in the local browser project and are not sent as classroom reports.
Can I resume later?
Reopen the saved project on this browser and account, or restore its JSON backup. Keep backups in a place you trust because they include your supplied material.
