Sikku: One Line

Draw one unbroken line from 1 to the last number. Reach the numbers in order. Fill every open cell. Three rules. That's the whole game. 200 puzzles across eight chapters, every one hand-picked rather than generated on the spot. The ramp is deliberate: First Light teaches the line on small boards, and by Singular you are on a seven-by-seven full of walls where exactly one route works and you have to convince yourself it does. Then it changes shape. The last two chapters add bridge cells: a cell the line has to cross twice — once sideways through the tunnel, once top to bottom over the deck, always straight through. • 200 puzzles — the first 50 free • Eight chapters, each in its own colours • Bridge cells, crossed twice, in the last two chapters • A best time and a flawless badge for every level • A hint when you are stuck. It costs the badge, nothing else • Progress follows you across…
