About this game

ONE LINE is an IQ based brain game. The best snack to activate your brain every time wherever you are. Routine and the excessive use of technology tend to numb your brain with certain behaviors and patterned ways of thinking, lowering your creativity and IQ levels day after day. Thinking on this, every occasion is a good one to give your brain a push.

This game uses technology to exercise your brain with simple but tricky puzzle levels, improving your IQ gradually. IQ results are provided with your progress. ⚯ ONE LINE is the best way to test your intelligence and logic skills. A couple of minutes each day will improve your brain abilities and test your IQ with qualitative and analytical scales.

Are you Einstein’s first cousin or dumb as a brick?

Just like knowledge does not occupy place, ⚯ ONE LINE will also not overload your device memory. This is a battery-friendly game, which means we will not drain your energy either.

⚯ ONE LINE features:
Challenging levels: find new tests with your progress and improve your IQ.
Hints: would you appreciate some help? Use hints to find the right answer for a difficult level.
IQ scale: just a small percentage of our audience achieve to complete our harder levels. Are you part of those?
Relaxing and Immersive environment: a minimalistic and beautiful design merged with soothing music will relax your muscles and tease your brain.
Ranking: show your friends who is the real genius by sharing some solutions from the harder levels or simply showing ⚯ ONE LINE ranking tables.

I love this game. I am very good at it for some reason, sometimes taking only seconds, but after playing it for about 6 months, I found that the skills, for me, easily transfered over with things like directions, say on a map and I could apply them to the best way to get somewhere. Or knowing spacial issues. It is also very helpful to me to check in with myself as to how my brain is logically functioning. I am old so this is important. Thanks

The gameplay is quick, responsive, and satisfying, which is great for me. I'm quite good at these sorts of games, so they tend to become kinda tedious & same-y when they aren't super challenging, especially when they give me a score after every single puzzle. This game doesn't waste my time with those flashy & unnecessary victory animations, it just moves right onto the next puzzle. I finally get to just enjoy the feeling of breezing through puzzles uninterrupted with a nice peaceful soundtrack.

Relaxing. Not sure how accurate the IQ numbers are. I've met me. No way I'm 175; levels 131-145. Only negative is the little arrows for when it's one direction only are hard to see. Sometimes they blend too much into the background. It would be nice to be able to maybe pick a different color for the lines or pick different colors for the backgrounds.
