Summary:
A brain-training puzzle game that activates your mind as you play.

How to play:
There is only one rule:

There are some fiendishly tricky, complicated puzzles among the large number of stages.
When you get stuck, make use of a hint.

Community Insight:
One-stroke puzzle game? Pause.
This game is 1 star without an ad blocker. But with Adblock enabled its actually pretty fun.
Lots of ads. Not trying to bring this app down.
Omg. Every phase is an add. Every new game is an add. Geez!!!!! Dont like it. Fun game but we watched more adds in this game than in our whole life.
Really fun and challenging (in a good way)! We would love to see a dark mode included. The white is just so bright. Maybe the developers could consider that.
The interface and game are very nice. HOWEVER, people will end up not playing at all if they have to watch that many ads! Seriously, Ive never seen so many ads in rapid succession in a game. Consider this, especially on lower levels, puzzles may only our take a few seconds to solve but then an ad takes MUCH longer than game play! People will stop playing before they ever come to love the game! To the developers, if people stop playing, you will earn a lot less money than if many more people endured a few sprinkles ads but kept playing. Consider the saying: It is better to earn a lot of nickels than just a few dimes.
So we usually like to give a puzzle game like this one about 25 levels before writing a review to get an idea of what the games like. We gotta say, we like some of the ideas going for it. The basic, non-gimmicky levels of were engaging and challenging and the shapes they used were tricky enough to keep your brain engaged. We enjoyed the couple of mechanics that the introduced (the one-way arrow and the double line) although they were HEAVILY under-utilized and left us with a feeling of disappointment with how they were handled. You see, when they introduced a new game mechanic we were expecting a new series of levels utilizing that mechanic (somewhere in the ballpark of maybe 10 levels that would utilize one or both mechanics introduced in tandem). Nope! It was just one level that utilized that mechanic each then went back to the old formula. We felt insulted to say the least and the levels felt rather boring after those introductory levels. Oh. And the ads. We dont usually complain about ads to much as we get it, the devs need to make money somehow. However, theres one peeve of ours that we didnt know we had til playing this game. Double up ads. What we mean is that this game is really sneaky. They have an option where you can get two free hints if you watch a short 30 second video. Which is fine. You support the devs, they support you in your journey through the game and youd be on your way. However, they slap another ad in your face without notice. You were told 1 ad, and instead you were given two. Its annoying. We really like this game overall. Theres just some things that could be worked out like utilizing game mechanics better, fixing some ad issues, and making the overall experience better for the player. If these get fixed, Im sure youll have a better player base overall.
We got this app to have something to distract us while waiting for the bus or for our classes to start, and it does its job. Im barely on Stage 3, but Im determined to finish all the puzzles by the end of the school year. We would say that our only issue with this app is that it has too many ads. Do we really need to see an ad every time we finish a level? It takes us a minute or less to solve each puzzle, so its just ad after ad after ad. For that reason, we cant give this app 5 stars.
Too many ads we like it doesnt take data but the qty of ads and the length of them, good idea but ooof find yall some faster ads or add mictrotransactions for like customization.
Game is fun but there is a video ad between every single puzzle. We paid $2 to remove ads and still got ads between every puzzle. Essentially they just took our money and ads are still there. Unfortunately we cant continue to play due to this.
We paid to remove ads but they are still after every puzzle.
The game itself is great, but the experience is spoiled by too many ads – pretty much an ad between each challenge.
You have to watch a long ad after every single puzzle Id rather buy the app.
This game is fun to play, but we only did level one because there was an ad after every single pattern we solved. Each ad was at least 30 seconds and about half were a minute long. We spent much more time watching ads than completing the problems which made us delete the app rather quickly.
Qung co nhiu v di, gy c ch cho ngi chi.
For every level completed we had to wait so long for the ad to finish. It ruined our game play experience. The game was fun but irritating.
We cant watch ads anymore to receive hints? Im stuck on level 5 stage 38~.
We love the idea of the game, but adds pop up after every single level making the objective of the game feel more like how many adds can you watch rather than how many levels can you pass. Very frustrating and a waste of time if you dont invest into buying no adds.
Idk if its just cause we were on the 1st level so it was easy but our goodness thats a lot of ads! Only had the app about 10 minutes before we got irritated and deleted it.
Fun but you watch an add every puzzle you solve. Some puzzles solve in 5 seconds.
A 30 second ad starts playing after EVERY little 2 second puzzle. No thanks, deleted.
We spent more time watching ads than playing game. We dont recommended this game.
2 30 seconds adds is too much, at least let folks get a few games in. Deleted immediately.
We love this game, but Ive completed all the levels and they havent updated the app in almost a year!!! Such a waste of money.
Every time we win a level we get an ad its would be a good game if there was not so many ads.
Too many ads every single time you play one simple level theres a million ads dont waste your time.
We really enjoyed the concept but Id clear a level in 5 secs only to watch an ad for the next 30. It gets exhausting very quickly when you are spending majority of the time looking at ads rather than play the game.
Lets you buy ad free then sticks an ad button where the next level button usually pops up every couple of levels. Fat chance thats an accident.
Too many ads, went 3 levels with 1 ad that forced you to play a game for at least a minute, and got another unskippable 15 second ad. Instantly deleted the app.
We love the idea of the game, but cant deal with the ads. Played 3 levels and spent 5 mins watching ads. Disappointing.
These pop-up games that are released once a week are simply ad farms. You complete a single puzzle in less than a minute, then get a minute-long unskippable ad followed by a screen thats encouraging you to download that app more for another 30 seconds to go on to another puzzle thatll take at most 40 seconds to complete. Tired of these low-rate game developers publishing these games to farm ad revenue and more than likely sell our data. Bring us back to when the ad was 30 seconds long every 10 puzzles.
We delete it too much frequent ads u cant even play.
Too many LONG ads, including ads that cant be muted. We dont mind watching some ads so the developers earn money off their game, but this is too much.
Too many ads. It dissuades us from ever recommending it or using it. We like the brain game but Ill stick to literature instead.
Youll spend more time waiting for the the ads to end then playing. Lots of ads! Dont waste your time.
Just an unbearable amount of adds. For a free game we expect some adds, but this seemed like a 3 second add for every 15 seconds of gameplay.
It took a couple of times to figure out how to play. Please consider instructions upon first time playing. We nearly removed because we didnt know what to do and couldnt figure it out, but overall after figuring it out, we can honestly say it deserves all five stars for keeping our mind sharp :).
Good game,we just downloaded it and it isnt like those annoying games with a ad every 5 seconds although it does have ads it isnt as much as usual games If you like a fun yet challenging game this game is for you, also people under the age rating may play it as there is nothing inappropriate its just a bit hard when you get up into the levels.
The game is fun to play the only downside is that there arent a lot of levels we have already finished all 10 levels(basic) and luminous thats about 9 levels.
We love this game but on Sirius level 30 you dont need the 2 lines you can make it with only drawing over that line once you dont need to make it two lines but other than that great game.
Basic level is just challenging enough to make you feel like you arent altogether stupid because you can solve the puzzle! We like that as someone who is not that smart but also easily bored.
Its a good game to keep you occupied for a bit but its too easy to figure out need to add something a little more challenging.
The game is great, dont get us wrong but there is a long add after every win! Every level. We found its quicker to close the game, reopen and move to the next level but after a while we. Began to feel its unnecessary. Please, the constant adds make it unappealing. Love the game though! We might make in app purchases but so many adds!! Get it, to many adds.
We were enjoying the game and wanted to speed through without ads so we spent that money to have it that way. But it still asks you to watch videos every so often when you finish a level. Ridiculous.
We had to restore our iPhone and we had to reinstall 1LINE . And we dont wanna have to start all over.
If ads were spaced out to every 4-5 puzzles Id have no complaints, but Ive spent more time trying to dodge ads than playing, ez delete.
We really liked the game at first, but it let us down. We love games that get us to use our brain and this one was doing a great job. But there are way too many ads. We had the game for 10 minutes and we saw 6 ads all the same -.-.
The game is so fun and challenging, but the ads are highly inappropriate. Many feature cheating husbands and nude women surrounded by puzzle games. Im deleting this app immediately. So disappointed.
Cant even get to the next level without being bombarded with multiple ads that bring you out of the game.
We dont want to say much . It has helped us a lot , there some lessons to learn from the game as well and its to stay focus and no matter how life is hitting you hard . Just be patiences and you shall definitely get through it just trust yourself and if you have played this games more like we have done you would understand us . Thanks we just VEGA on the Luminous stage.
