About this puzzle
A 20×20 picture with 222 of its 400 cells filled (56%). The clues contain 118 blocks in total, and every one of them can be placed by line logic alone.
Before you mark anything, the overlap rule already settles cells in 17 of the 40 lines.
One line is filled from end to end.
The longest block is 20 cells long; the busiest line holds 7 separate blocks.
Where to start
The best opening is row 13 (clue 3 12 3): on its own it fixes 20 of its 20 cells.
On 20×20, keep a rhythm — overlap, edges, crosses — and revisit a busy line only after its neighbours have changed.
