Puzzle IO - Binary Sudoku

Warning: ad-free breaks hints! I really enjoy this, it’s simple and straightforward and it’s an entertaining puzzle. And I really appreciate the ad-free option so you don’t 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. I tried emailing the devs about this months ago and they never responded to me.

Great Puzzles w/ good mix of challenging & brainless I have played this daily since finding it a few weeks back. I 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. My 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 didn’t detect it or if it’s just lagging. I frequently tap four to eight times to get my choice. Slightly clunky, but not gratingly so. Unfortunately it’s straight up problematic if I’m working on the last empty cell in a row or column. Regularly the wrong option is easily read as an error. (By this I mean, the line is checked before my final tap.) One error equals the loss of the three lives allocated for each game. I’ve adapted by forcing myself to slow down and focus when working on the last empty cell. Though this reduced my official game errors, I’d 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 my choice is correctly displayed. I also stop playing the game each day the first time I’m prompted to earn new lives because of interface errors instead of my actual mistakes. Again, the actual game design is visually attractive and fun to play.

Ads ruin it 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

I’d give zero stars if I could The puzzle itself isn’t bad. But the ads are the most annoying and pervasive of any puzzle I’ve downloaded. Truly a waste of time.

So many ads With the new update you have to click through 3 pages of ads now to play. I know somebody needs to pay the bills, but this is irritating. I play half as much now.

Please add dark mode game play!! I love, love, LOVE this game. I love to mindlessly play it because it helps my brain focus on what i’m hearing. Another time i really like to play is when i’m trying to fall asleep. With my phone even on it’s darkest setting, it’s still much to bright to play when I’m 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! I’m a teen and I’m not huge fan of going on social media while i’m around others (because I don’t pay attention to them) and I also have no other games on my iPhone, leaving this app my go to option for really any entertainment. I alone have made you guys a decent amount of revenue just from the ads I 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 it’s a 5 star game all the way.

Ad is not loading/can’t play the game I recently found this game and really enjoy it but haven’t been able to play now because ad is stuck and won’t load. It’s just there. I 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.

Ads aren’t loading, preventing from game playing Starting as of yesterday, the FaceBook Ad specifically tries to load but can’t and then I can’t play the game. This happens on two of my iOS devices, neither have ad blockers. Same happens on cellular vs WiFi. Deleting the app and reinstalling it lets me get through the tutorial and play 1 quick game but then I’m 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 doesn’t respect the silent settings of the phone. That should never be allowed to happen. Other than those issues, I love the game and it is the best version I’ve found. Really wish the ad issue would be fixed.

Love the game, app keeps crashing Updated my app yesterday, still crashing ☹️ hope this bug gets fixed!!!

One flaw Really good game but unless I lack a little brain knowledge, there’s no way I can guess which number goes on a specific box
