What are one line games?

One Line games are browser-based titles built around one line-themed gameplay. Every one line game in the PlayKovo library is HTML5, which means it loads instantly in any modern browser with no plugin or app required.

One-line games are built on a single, clear idea: draw, drag or trace one continuous line, and the puzzle is solved when the line has done its job. It can be connecting every dot without lifting your finger, guiding a path around obstacles or drawing a shape that holds a ball. The rule is so simple that you understand it within seconds, and the challenge is working out the route that fits. Levels are short, so they are easy to play in a spare minute.

How to get better at one line games

Every one line game has its own controls and mechanics. Read the "How to play" and "Controls" sections on each game page, then practice — that's the fastest way to improve.

Look at the whole picture and plan the route before you put your finger down, since a line cannot be undone halfway in many of these games. Start from the point that has only one way in or out, because that end is usually the start or the finish of the solution. If a level seems impossible, check whether you are crossing a point twice or leaving one out. Restarting is free, so treat the first attempt as a test of the layout.
