⊷ ONE LINE is a 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?

Fun and relaxing

I’ve really been enjoying this game. I’m always on the hunt for games I can play on the train while listening to podcasts and this has been perfect. For the most part this is beautifully made, but there are a few things I’d like to see improvement on.

First, the ads are insane. I finally paid $1.99 to have them removed because even if I turned the sound off on the game the ads had sound and there was an ad after almost every round (which sometimes only takes seconds to complete). Second, sometimes the line freezes and I can’t keep drawing to complete the puzzle and have to force restart the app. It’s also been glitching where a phantom line starts jumping around the screen when I’m drawing. Third, a minor thing, but consistency with the line thickness throughout the game would make this a lot sleeker. Sometimes the line is super thick and large and other times it’s super thin and tiny.

I also don’t quite understand the IQ score, it’s a little strange. I think just changing it to a game rating would make more sense for the user, IQ score is not real and confusing.

All in all still love this game and hope the developer continues to improve on it!

To many ads

Don’t get me wrong this game is AMAZING, but there are MANY ads. This is all I have to say about this game.
