A word search where the words are numbers — and you have to earn each one. Every clue is a small maths problem: an addition, the smallest 3-digit prime, the lowest common multiple of two numbers, the next term in a sequence. Its answer is hidden somewhere in the grid of digits.
Clues are written so that each has one answer ("the smallest…", "the largest…"), and every answer is placed in the grid exactly once, so there is never a second spot that also reads right.
Big grids with all eight directions are a real scanning workout. Start small with → and ↓ only.
Solve each maths clue, then find its answer hidden in the grid of digits.
