Still Life
Picture Logic
A nonogram is a grid with numbers down the side and across the top. The numbers tell you how many squares in each line are filled. Work out which ones, and a picture appears.
Every puzzle in Still Life is machine-checked before it ships to have exactly one solution reachable by logic alone — so you are never asked to guess, and being stuck always means there is a deduction you have not spotted yet rather than a coin to flip.
