01 / Choose
Keep the ingredients recognisable.
Use a few matching pieces or draw the same simple shape in several positions. Limit the palette so a change in orientation or spacing remains easy to notice.
Decide which property will matter first: a turn, a position, a filled area or the way two edges meet.
02 / Build
Make the rule visible before hiding a piece.
Arrange several examples that follow the same relationship. Check that the chosen rule explains each one.
Leave one position open and imagine what would complete it. If several answers fit, decide whether that ambiguity is part of the puzzle or whether another clue would help.
03 / Explain
Give the answer a reason.
Write a short explanation that points to the actual details in the arrangement. Avoid introducing a new rule only after the open position appears.
Try a second interpretation yourself. It can reveal whether the puzzle has a clear centre or needs a more deliberate clue.
04 / Share
Listen to the first reading.
Show the arrangement without giving away the intended relationship. Ask what the other person noticed and what supports their answer.
Compare their reading with yours, then revise a single clue if needed. A different explanation can be useful material for the next puzzle.
