Connect the colored dots by filling the entire board. Think ahead and then drag the line to fill all the space to complete each level. Keep filling up the boards, trying to complete all 50 levels. If you're stuck at any level, check out our helpful step-by-step video.
Every stage hands you a small, self-contained problem with a clean answer somewhere inside it. Matching three, sliding blocks, connecting pipes, rotating tiles; the mechanics change but the feeling is constant. You test an idea, watch it fail, adjust. Later stages layer two or three rules together so the obvious move is usually the wrong one. It is quiet, methodical play.
Short, finishable chunks. A stage of Merge Fill takes a couple of minutes, which makes it a good match for a wait at the bus stop or the last five minutes of a lunch break. It loads in a tab without an install, so there is nothing to clean up afterwards.
Suits adults who want a calm break and children old enough to read simple instructions. Casual players will find the early stages gentle, and anyone who enjoys sudoku or crosswords should feel at home.
