Community Insight:
One of our absolute favorite puzzle games. Level 11-31 and still going strong.
Is that pretty fun game other than the stupid idiot ads.
Do you know the button where you click to watch an ad and you get 100 coins while we watch it twice so then we could ask for a hint and it didnt give us it. Im still at 80 coins, and this is making us really mad because we had to sit through two ads and now Im gonna have to sit through more because we didnt get our hundred coins so does has this happened to anyone else and can you tell us what you did and thats up please thank you.
There are way to many adds and it gets on our nerves . When we click on the get more coins button , it says to watch an add. But EVERY time we watch it it never gives us any coins back! Its so annoying !!! But we love this game , but it has way to many adds and its a scam.
This is a very relaxing game there may be ads here and there but still a great game.
Overall it was a fun game but whenever we got it on the second try it would only give us one star not #3.
We just love the line puzzles! And, anyway heres a funny secret to get 3 stars on any level: Make sure that when you are making your solution to not let go.
We love this game but there are way to many ads which make us dont want to play it as much.
Its the best we live it and its the best game Ive played and we like it because none of them are hard and its gives you pointing you can get hence if you are a little bit stuck its the best game we would recommend you to play this game in app stores now go check it out its the best.
It really jeep our mind busy . One of the best game to relax.
We just love how hard and challenging it is.
This wont be boring. It will challenge your abilities. Not too much excitement but it will make you think.
We found this game ages ago, and we always come back to it. We had to use hints when we first played the game. Yet, after seeing familiar patterns it becomes intuitive.
We don't play games with ads. We're quite willing to pay to get rid of the ads, but we can't find any option to do that. We've kept the game on our iPad, and check periodically to see if you've added a price to be shed of the ads.
. . . So this is a good game for us. We dont have any problems with ads, probably because we use a blocker. At some point we may need the ads for coins for hints, thats usually how this goes. We dont whine about it, not much anyway . We simply play solitaire on our MacBook while the ads run.
The game overall is fun with some challenge but after ever one or two levels theres an add which can take up the 30 seconds after that you can play one more round and then theres another add. Disappointed, frustrating.
We absolutely love this game however the ads are just to much. You have a next button and you have a 5 x button either one you choose you have to watch an ad. We suggest that you change the next button to every three or four times and the 5x button you always watch a video. As much as we love this game it doesnt seem fair that you spend more time watching ads then you do actually playing the game. Some of the more challenging ones take longer but the ads are currently taking up far more time then game play and that is what makes it annoying. We you are competing with thousands of other games out here you would think you would want to keep your players playing your game, but most of the time we just move on because we get bored easily with such a huge pile of ads. We are here to play and take our mind off life not be pounded with ads for crap we are not interested in or for other games we already have downloaded.
Nice game. Makes you think. But theres an ad between each level and they are long ads. Im spending more time on ads than the game. Probably wont play much longer. Its just not worth it.
Its an interesting game but the puzzles take about 5 seconds and then you have to spend better part of a minute watching an ad. In between every. Single. Puzzle. So by downloading this, what you agree to is to just basically watch ads full time with short, intermittent little diversions in between. If this doesnt sound like your idea of fun, dont bother downloading this.
So we absolutely love this game and Ive been playing it for like 5 years or something across multiple devices and having to restart completely. Well we lost our enjoyment for the game when they implemented the star system we guess you would call it. Well we cant stand completing a level 3 seconds after opening it and being told we get 1 star. We dont even understand the method they use to decide how many stars a completion receives. Im convinced its randomly generated to make you upset about how you can get 3 stars that way you spend more time on the game. We could be wrong, but yeah the star thing really pisses us off. You should just get a completion and move on. None of that supervision star crap.
This used to be a fun game, hadnt played in a few years but came back to it and now there is an add every time you finish a level.
We spend more time waiting to clear the ads than it takes to do a puzzle. Puzzles take about 5 seconds and ads take about 20 seconds. And they're after every puzzle.
We tried giving this game a chance but when you only get 2 or 3 rounds then a 30 second its not worth your time. We could understand if it was like that every so often but these ads are like clockwork. Wash. Rinse. Repeat.
It definitely works both sides of our brain. We try to see how fast we can complete each puzzle. The ads are a little excessive at times but we still play.
We loved this game two years ago and would play it nonstop. Its just such a perfect pass by game that allows you to play whenever you feel like it. We would even dream about this game because of how much we played it. We would challenge our friends to beat a level. We have beat this game not once, but TWICE!! Honestly we loved this game so much. We would love to see this game get more new levels! We dont know if that can be a thing anytime soon but to get back into the grind would be a great way to start 2022 off :).
Been doing this game since 5 years ago and Im on level 897. Cant stop wont stop.
We like this game. We had in 2019 and we decided to play it again. We hate how it changed a little bit and we think the new themes are ugly. Also some people complain about the adverts. You can just turn off the wifi and the game will be fun. But you have to do it every time you start the app! Can we just remove them permanently without paying.
This is one of our favorite mindless games. We like that you don't get too stuck on the rounds, and you're more likely to complete them than in a game like Dots (which is based completely on luck sometimes tbh). Also, you can mute the music and whatnot in settings. We have a few nit-picks tho: –As you can see in the other reviews, the ADs are insufferable but can be paid off for $2.99. –There's now an arrow pointing to the hint button which is rather annoying. –we just now realized how you get 3 stars in the rounds. As long as your finger stays on the screen, you'll get 3 stars. If you take your finger off the screen once you get 2 stars, twice is 1 star. That's kinda an unfair way of rating. You can spend 10 minutes figuring it out, but as long as your finger stays on the screen you get 3 stars. It should be rated based off of time and not how well you can keep a finger on a screen imo.
In order to gain more coins youre promoted every level to watch an ad for 5x coins, the problem is that whether or not you choose to watch the ad to get to the next level, you still get at least 90% of the same trouble. We fully disagree with this structure. We give an extra star, because the level creators are obviously putting in work, and we appreciate the new colors. Our bigger problem is the time cap, whether you want more value or not, you get the same time spent, its a false choice. We do wish we could go back to our older account, where you could just play. Im not mad at free games for having ads, but it is usually that to get more you spend- more time you use on it. There is no choice in that in this. Time- in every level- is spaced by income-boosts. Its honestly sad that youre punished for either. Edit- Removing a star, because even if you buy no ads, you still only get coin boosts prompted every level via spending time. We dont want to wait 30 seconds of intermittent closing in order to earn more coins, when Ive spent more than a good steam game overall. And oh, fun fact, if you pull out of the app to check literally anything, the ad is restarted, including where you have to interact & close the ad, just to restart is again. So yeah, get a drop down text and reply? Interact and restart. In-between levels and decide to look at your messages (or any app at all)? Oh, close the ad, and the 30 seconds restart. Its sad. Ive played this game so long among multiple accounts, and Im still treated as a time and money cow, and so will you be.
Too many commercials to enjoy the game.
Watch a video to get a bigger prize. Finish video on numerous times, but game states video was skipped and no prize given. Greed getting the better of you. Game deleted.
This might be a fun game but we ended up deleting it because the insistent ads are one of the most annoying Ive come across. It takes 3 taps for you to finally click out of the ad to play another level. You can go through each level within a few seconds so you end up watching more ads than actually playing.
Love Love Love it doesnt get no better than this.
Now right out of the gate we do pay to remove ads so we wont complain about the obvious, that being said Ive seen a lot of older reviews talk about the hint system and Ive seen no issues with how it is as of today(if you run out of coins and dont wanna watch adds just redo earlier levels to get coins again) now difficulty scale is perfect from single lines, to doubling back, to having no set end point and the concept is a simple way to work your brain and pass time we highly recommend it! The sad part is Ive just completed the 2600 stages and saw that the last set added was 2 years ago :,( will there be more.
Yabbity dabbity dabbity dabbity dabbity.
Its a great game to play when your bored and its a good problem solving game.
We wouldnt say this game is particularly difficult, so if youre looking for a challenge, this isnt really the game for you. Still, its pretty fun since you can just fly through the levels, and although the ads are somewhat annoying, theyre not excessive or overdone. Overall, its a pretty decent game and good for killing time.
Ok Literally theres like so many ads.
It is a very fun game we just wish the helpers were a bit less than 200 and wish they were 100.
The game is good and it challenges your mind, a good past time. But there are a LOT of ads.
First, ads are way too frequent. Second, its extremely irritating that if you take even 3 seconds to think, theres a flashing hand pointing at the hint button. Seriously, we have eyes, we can see the hint button. You dont have to constantly point it out. Its annoying and distracting.
Love the game but way to many ads during game play.
This game is good but if you fix Game Center achievements Ill change back the rating. It had an error long time ago. 3 stars for now with ads or without WiFi offline.
Its a great mind squeezer, but there are so many ads its not even enjoyable. 2 stars.
The game used to be fantastic until they added the aspect of starts and a time limit to complete it to get full stars it makes it way to difficult to get 3 stars to actually enjoy it it just becomes frustrating to complete each level fully and not enjoyable at all.
Way too many pop up ads, detracts from the game and makes it more annoying than fun.
The levels arent too challenging, but they are addictive. It takes only a few seconds to solve each one and you are rewarded with 30 or so seconds of ads as a reward. Why would we play a game that we can only play for 10 seconds before watching another ad? Its getting deleted.
We love this game, but the hint mechanic is the most annoying thing ever devised since the invention of highway traffic. As someone who doesnt use hints it is supremely annoying when we are prompted to use one no more than 5 seconds (we timed it) into a level. This happens to us on EVERY level and ironically the hint mechanic cant take a hint, we WANNA SOLVE IT ourselves!!! In an effort to make this stop we decided to go to an easy level and purge all our money to eliminate the possibility of being able to use hints but it hasnt worked. GAME DEVELOPERS- Please change this game mechanic, it is SOOO annoying. (Maybe a turn hint suggestion off button?? Just an idea…) we like many others am looking for a mentally stimulating puzzle game that doesnt try to force spoon fed answers down our throat. If you fix it, Ill give you 5 stars. Until then you get 1. Good game, but annoying hint mechanic. No offense.
We love this game we just downloaded it and Im having so much fun! We love that there arent ads after every level! Its so fun and it gets your brain working. We definitely recommend this game.
We have anxiety and Tourettes and this helps tremendously when we are in public. Especially churches.
