Kick back and relax with this minimalist puzzle game!
Lines (Free) is a puzzle game with a simple premise. Match up pairs of colored points while connecting every available dot and without crossing any other lines.
The game features a clean, minimal design with several audio and visual options. I found being able to change the background color helpful to ease eye strain, especially if you're stuck on a level and have been staring at it too long. I feel like the option buttons could've been better represented with icons as opposed to letters, but once you try them all out it's easy to remember which one does what.
Lines allows you to move back while connecting dots as long as you haven't fully completed a colored pair (in which case you have to start the pair over from the beginning). This lets you work out which direction you need certain lines to go and is very handy on the trickier levels.
Speaking of which, it seems like level difficulty after a certain point kind of goes all over. One level can take a while to figure out, while the next one almost completes itself. I imagine luckily spotting a key play can make a puzzle seem easier than it is, though.
While playing, I was reminded of another title I played long ago on Kongregate. There's a game mode in Picma called Links which has a similar feel but works a little differently. If you enjoy Lines, I highly suggest giving Picma a try as well.
One last thing before you play Lines, though. You should know it throws multiple achievements at you for completing each level. Some people have pretty solid opinions on games with achieve spam, but at least it requires you to actually play the game (instead of just idling it like the worst ones do).
