Sharpen your mind with a connect-the-block-style one-line brain training puzzle game. A simple but addictive one-line puzzle game that’s completely free to play. Your brain becomes more active the more you play. During your commute, before you sleep… enjoy downtime with brain training. The rules are extremely simple. Just fill in all of the blocks using only one line. Use hints for puzzles that are too hard to solve. Hints are also free, of course. 4 levels of difficulty. A whopping 2,000 puzzles. Don’t get too cozy—the puzzles get harder as you go along. One-line puzzles are mathematical problems with origins in the early 18th century. First posed in Königsberg, the original puzzle revolved around the town’s Pregel River. Mathematical thinking is said to increase work efficiency and prevent aging.

  • Ads are too frequent

    Don’t bother
  • I love this game, but a few flaws

    By MonkeyLizzy23
    I love this game because it has you addicted while still using your brain for 110% of the time. It also has a clean feeling and look to it while playing. What I don’t like about this game is that there are adds after EVERY SINGLE LEVEL!! I don’t like adds and I find them very, very annoying... so when they pop up after every level I get very angry. Overall i love this game and recommend it.

  • Ads make this unplayable

    Full screen ads that force you to interact and no way to X them out makes Fill so frustrating to play.
  • fun but...

    It's fun, and my family is obsessed, but we can all agree that there are a lot of ads. I really like it, and it makes you feel like a puzzle genius when you get one right. Great job whoever made this! It's amazing.
  • I think it’s fun but!

    I think it’s really fun! I don’t find the ads all that bad either. But the level design is repetitive. It seems, or maybe even is, some few fun levels but flipped over and over. Maybe that’s just me though.
  • Such a fun game!!
