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. Whether math is your bane or your forte, be sure to give this game a try. You’re sure to get hooked on these puzzles!



  • It’s awesome

    Wish the levels would get harder quicker but it’s still really fun 😊
  • Free hint giver doesn’t work

    So each time I watch an ad for free hints, it doesn’t work! I seems like I watched it for nothing.......
  • I never right a review but I have a bit of a complaint

    By User9439
    I really enjoy this game, some levels are challenging. However, I find it oddly unsatisfying because the rewards are only hints. I never use those hints. I think there would be more incentive to advance in level and not get bored if you can reward players with cosmetic items, maybe golden shiny roads as a swiping skin, or a rainbow road. Etc. Or maybe a little car as a leading marker. Idk, but hints are not a reward.
  • Challenging and addicting

  • Fun but too easy

    This game was challenging at first but then I flew through the first 100 levels and realized the next bunch weren’t any more difficult at all. It needs to add more challenge— like much larger maps, timer etc. The way it is now, I can fly through each one in a few seconds. Too bad I paid $2.99 to remove the ads.
  • Good stuff.

    Yeah, like, it's pretty good. There's a hell of a lot of puzzles to do. Advertisements get annoying so I'd say the game is worth $3.00 for sure, and the earlier on the better because you'll be watching an advert every 3 puzzles which you'll likely end up going through pretty quick. There's a few pleasant little tunes that cycle between levels so that helps to prevent getting sick of hearing it. Good job, even if the working title is a mouthful.

  • Pretty fun BUT...

    By Rickspindrift
    Since the last update, when you choose to watch a video to get a hint, it doesn’t give you the hint about 90% of the time. (and yes, I watch the video all the way to the end) PLEASE FIX!
  • Oh the ads!

    Half my time spent with this app is staring at ads. It’s almost unplayable as a result.
  • Too easy

    By AncientJewishToilet
    just the way everything is setup to begin with doesnt leave that much room for getting more difficult. not trying to brag but i don’t understand how this is challenging for anyone at all maybe children. havent used any of my hints i dont even know what hints theyd even give you without just completing it for you. on level 4 now so we’ll see :/
