Preparing preview…

Start in three steps

1

Choose a practice set

Pick a real 4×4 or 6×6 level, puzzle count, symbols, paper, and answer options.

2

Check the preview

Confirm the symbol key, board size, page count, and worked example before printing.

3

Print or save the set

Use browser Print or vector PDF after the current validated preview is ready.

Choose the right support strength

Guided introduction

Use the Rules Introduction preset for one 4×4 board, visible rules, and a worked example.

Light support

Keep the symbol key and rules visible while children complete a same-level home set.

Independent practice

Use a classroom set with answers kept on separate pages for later checking.

Progressive challenge

Move from supported 4×4 boards to admitted 6×6 reasoning without opening larger grids.

Suitable learning settings

Short home practice Complete one board and explain one decisive move in five to ten minutes.
Partner or small group One learner names the rule while another places the symbol and the group checks it.
Independent quiet work Use a same-level set with the answer pages held back until every puzzle is complete.

Printing and use tips

  • Keep symbols easy to scanUse color for first practice or low-ink and line-art when strong outlines are enough.
  • Use pencil for reasoningLet children mark uncertain cells lightly and erase revisions without damaging the board.
  • Keep answers separatePrint answer pages for later checking instead of leaving them beside the active puzzle.

What children practise

Rule-based deduction

Every move can be linked to a visible count, pattern, or line comparison.

Two-direction attention

Rows and columns must be checked together rather than solved in isolation.

Focused self-checking

Children sustain attention, compare with answers, and revise a mistaken move.

Use the printed sheet in three steps

Observe one useful line

Circle or point to a row or column with enough given symbols to reveal a pattern.

Solve and explain

Place one symbol only after naming the count, no-three, or different-line rule.

Check and reflect

Compare with the separate answer page and revisit the first move that went wrong.

Ready to reason?

Start with one legal move

Open the focused board, choose a symbol, and explain the row or column rule behind your next move.

Binary Logic questions

Is Binary Logic a maths test?
No. The values are two stable identities. You can use suns and moons, shapes, nature symbols, or 0 and 1 without changing the logic.
Does a hint fill the cell for the learner?
No. Hints first identify a line, then a rule and evidence cells, and only finally reveal the conclusion. The learner still places the value.
What makes a puzzle harder?
Size, strategy requirements, cross-line dependencies, and working-memory load all contribute. The number of empty cells alone is not a reliable difficulty measure.
Can I print the exact puzzle I am playing?
Yes. The online print action uses the current deterministic definition; printable sets use one exact Document Plan for preview, browser print, and PDF.
Are 8×8 or 10×10 boards available?
Not in the current product. Only 4×4 and 6×6 are admitted for play and print; larger boards stay unavailable until their separate evidence gates are satisfied.
