One clue per block. The number on it is how many letters its answer has.

Drag across letters to spell it. The path steps orthogonally and never reuses a cell.

Blocks wants each answer to fill its rectangle. Freeform lets the path snake, under the same no-reuse rule.

Words read either way round, so an answer found backwards still counts.

Both modes are that day’s board for everyone, and both are ranked.
