Scanning a grid of jumbled letters for hidden words, pencil in hand, while half-listening for the next boarding announcement — a low-pressure puzzle that suits any attention span.
Pick a theme, brainstorm words, and fit them into a grid with clues you write yourself — a challenging way to practice vocabulary and logic while creating a puzzle someone else can solve.
A numeric grid puzzle, part crossword and part sudoku, where you fill cells with digits 1-9 so each run adds up to the sum shown in its shaded clue cell — and no digit repeats within a run.
