Cosmos Lines
Cosmos Lines is a relaxing, minimalist puzzle game where your goal is to fill a grid by drawing lines. Every line you place has a strict length limit dictated by a specific number, forcing you to think carefully about how the pieces will fit together before making your move.
The core gameplay loop is slow and thoughtful, accompanied by a soothing, mystical atmosphere. Since there are no timers or fast-paced threats, it is entirely about logic and visual planning as you uncover the correct layout for each board.
Controls
This game uses simple point-and-drag interactions:
- Mouse: Click and drag to draw a line of the designated length.
- Touch (Mobile/Tablet): Tap and drag across the grid to place a line.
Tips for Success
- Work from the edges: It is usually easiest to fill the corners and border spaces first, as they have fewer connection options.
- Count spaces carefully: Make sure you know exactly how many tiles a numbered line needs to cover before committing it to a narrow corridor.
- Use the hint system: If you are completely stuck on a board, use the built-in hint to reveal the correct placement of one line, then build out from there.
Cosmos Lines runs effortlessly in the browser, making it a great pick for quick puzzle sessions during breaks without needing to install anything.
