Press on the first letter of a word and drag to the last. Let go, and if it is on the list it crosses itself off.
Prefer clicking? Click the first letter, then the last. Clicking the first letter again takes it back, and so does Esc.
Words are traced from either end. The grid does not care which way round it hid them.
A word appears on the grid exactly once, so a run of letters that spells one is always the one you want.
Two grids a day, both on the same theme and both the same size. Each keeps its own progress.
The two grids are the same size, hold the same number of words and hide
them the same two ways. The only difference is the label: an
Unlabelled jar does not say what is in it, so the list starts as
ten blank rules and fills in as you find them. New theme at
midnight UTC.
