Player Experience Highlights
Community Insight:
We really enjoy this, its simple and straightforward and its an entertaining puzzle. And we really appreciate the ad-free option so you dont have to constantly watch ads. But one warning: if you buy ad-free, it breaks the watch ads to get a hint buttons, so you can no longer earn extra hints. We tried emailing the devs about this months ago and they never responded to us.
We have played this daily since finding it a few weeks back. We even splurged for the ads-free version (reasonable one-time fee). The gameplay is deceptively simple to learn and enjoyable for logic and puzzle game aficionados. Our only complaint is a glitchy interface combined with an automated error-check that utterly fails at distinguishing between genuine user error and said glitchy interface. Simply explained, there are only three options for each cell: circle, X & blank. One tap is circle; two taps, X; & three taps is back to blank. Often there is a lag after a tap. Unsure if it didnt detect it or if its just lagging. We frequently tap four to eight times to get our choice. Slightly clunky, but not gratingly so. Unfortunately its straight up problematic if Im working on the last empty cell in a row or column. Regularly the wrong option is easily read as an error. (By this we mean, the line is checked before our final tap.) One error equals the loss of the three lives allocated for each game. Ive adapted by forcing ourselves to slow down and focus when working on the last empty cell. Though this reduced our official game errors, Id prefer to either be asked if the line just completed is ready to be checked or simply to have a separate way to submit it once our choice is correctly displayed. We also stop playing the game each day the first time Im prompted to earn new lives because of interface errors instead of our actual mistakes. Again, the actual game design is visually attractive and fun to play.
The game is great, but the ad time is over a minute and you have to close multiple windows, basically ruins any consistent play. The positive is you usually only do 1 puzzle then close the app because of it.
With the new update you have to click through 3 pages of ads now to play. We know somebody needs to pay the bills, but this is irritating. We play half as much now.
Really good game but unless we lack a little brain knowledge, theres no way we can guess which number goes on a specific box.
Easy to use and fun to play. Im addicted.
We love, love, LOVE this game. We love to mindlessly play it because it helps our brain focus on what im hearing. Another time we really like to play is when im trying to fall asleep. With our phone even on its darkest setting, its still much to bright to play when Im trying to wind down since the game uses a mostly white background. Not only would adding this feature integrate the app more seamlessly with iOS, but it would make it look a lot more professional with this useful, new feature, putting it further above similar apps and making it the obvious choice for users! Im a teen and Im not huge fan of going on social media while im around others (because we dont pay attention to them) and we also have no other games on our iPhone, leaving this app our go to option for really any entertainment. We alone have made you guys a decent amount of revenue just from the ads we watch between puzzles, so the least you could do is make a game-changing addition of dark mode for your biggest money maker :) Other than that its a 5 star game all the way.
We recently found this game and really enjoy it but havent been able to play now because ad is stuck and wont load. Its just there. We use ipad with iOS operating system. Is there any way to remove the ad? Saw someone else say they removed app and then reinstalled but they had same issue. Thanks for supporting a great relaxing game. Would like to play it.
Starting as of yesterday, the FaceBook Ad specifically tries to load but cant and then we cant play the game. This happens on two of our iOS devices, neither have ad blockers. Same happens on cellular vs WiFi. Deleting the app and reinstalling it lets us get through the tutorial and play 1 quick game but then Im stuck with the same issue. Also, some ads that play noise like the freeze the spider ad, plays noise even when you have the phone on silent and doesnt respect the silent settings of the phone. That should never be allowed to happen. Other than those issues, we love the game and it is the best version Ive found. Really wish the ad issue would be fixed.
Updated our app yesterday, still crashing hope this bug gets fixed.
These puzzles are loads of fun and they keep your brain sharp.
This game loads quickly, and is very enjoyable. A great game to pass the time.
This game is very cool but some of the easy generated levels are harder than some levels marked as hard.
Love the layout and how quick it is, but the nightmare puzzles seldom show up when you click on them. Id welcome more challenging levels.
It was very fun playing this game wish it had more puzzles.
We really enjoy playing this, but these pornographic ads are a little ridiculous. This game said age 4+ and has ads for porn, all body parts showing. We hope the makers fix this or Apple removes the game.
Great game!!! However when playing the game froze and tapping to get it restarted resulted in a pornographic video to play on our phone. Completely unacceptable.
It was good until they force you into things you don't want to do. Bad move promoting us to login to Game Center every time we start the game. We don't want to have to tap other buttons and we don't want to login into anything either. Who really uses Game Center anyway? It's lame.
This is the best version of this game we've found. Sometimes the color correct answer doesn't show up, it just spins in black and white; but a minor glitch. It's good for quick games! But, why is the hard version harder than expert or nightmare? And why is nightmare easier than expert? Seems counterintuitive.
Love the puzzle and now we can play anytime.
Only wish you could get hints during play.
Im a fan of binary math and this is perfect. Please keep this updated.
Thanks for the game. We learned how to play this game in a puzzle book and love that we can play it any time now.
This is the best and only binary game app you need. Great tutorial and lots of levels to play. Quick games to OMG games. Super easy to use. Love it.
Awesome. Good help & tutorial, hints available if you need them, earn more hints as you go, and NO advertisements.
The constant prompts to review the app.
We wish there was an option to pay a small price to remove the ads. We'd pay up to $2 or $3 for that option.
If the timer could be turned off, this would be a 5 star game. We hate to be timed…we like a relaxing game.
Fun, brainy, and addicting. This game has quickly absorbed the majority of our sitting-around time. Not difficult to play, but definitely a challenge cut into short, enjoyable games.
We've been looking for this game for a long time…ever since we got addicted to Binario on a daily calendar. This is perfect. Now we can get our daily fix.
Good game. Simple, straightforward UI. Fun if you like binary suduko.
