The awkward twenty minutes. Waiting for food, waiting for an appointment, an hour into a drive with a long way still to go.
This is one sheet that lives in a glovebox or a bag and covers all of them.
What is on it
A dot grid for dots and boxes, big enough that two people can play a real game rather than a token one. A twenty-five square spotting bingo card that works on any road anywhere. Six noughts-and-crosses boards, because the first three always end in draws once you have both worked it out. That is the whole page.
Why one page
Because a booklet gets left at home and a printout gets used. The constraint is deliberate: everything has to fit on a single sheet that costs nothing to reprint when it comes back covered in pen.
Print a stack
Ten copies, folded once, in the door pocket. It is free, so the correct number to print is “more than you need” — the sheet only works if losing one costs nothing.
