I was originally hesitant when considering buying this game, as it didn’t have any written reviews. I played the NYT daily puzzles, and really enjoyed those, so I craved more. I tried searching both on the App Store, with not much luck, and on the internet, which felt clunky and full of ads. When I say this app is pretty much perfect, I mean it. It doesn’t feel clunky, there’s extra modes, pretty much unlimited puzzles, leaderboards, achievements, etc. It’s a lot of fun, and gives more than just the daily puzzles which was exactly what I was looking for. The only thing I wish was different is if you could create custom names for the leaderboards, which I don’t see an option in the app for, but I could be missing it! I understand the hesitancy with that, as I’m sure it isn’t easy to ensure that no inappropriate names are displayed on the leaderboard, but if there’s a way to implement that, that’s the only change I would personally make. Overall an amazing game and definitely deserves its first written review even though I don’t usually write reviews. 5 stars! :)

This genuinely made my day, thank you so much for taking the time to leave the first written review, it means more than you know!Youre also spot on about custom leaderboard names - it's something I'd love to add. I’ll see if i can get something in the next update to address this directly!I’m so glad the app hit the spot. Enjoy the puzzles!!
Love!

Can I just ‘ditto’ the other review? Like spot on! I was hesitant but really wanted to keep playing Pips after finishing the NYT ones. Beyond my expectations! No ads, easy to use, non-stop games at different modes — and the leaderboard was a fun surprise! I love seeing how I compare. (In fact, got #2 recently and made my day!!!) also, the ghost mode is a creative twist! I was surprised I could do it, lol. I guess only feedback is keep the variations and ideas coming! Oh, and recently the tiles are getting stuck? Best way to explain would be like when you get water on your screen and try touchscreen.

This made my day!! Thank you! And #2 on the leaderboard is no joke, congrats!Really glad Ghost Mode clicked for you, it's one of those features I wasn't sure anyone would actually enjoy, so hearing that means a lot.The stuck tiles issue has been fixed in the latest update (1.4.7), so it should feel much smoother now.And on the leaderboard front, I'm working on adding personal names so you'll be able to see who you're competing against, and this will be coming in the next update!Thanks for playing and for taking the time to write this. More variations and ideas are definitely on the way.
Love it, but it has some quirks?

Huge fan. Play this game constantly, but I have noticed some quirks that are beginning to annoy me. 1. I really love Expert mode, but I feel like I’m seeing the same 4?5? puzzles over and over. Not just the shape, but the actual tile placements are all the same? Are they not randomly generated? 2. Like someone else mentioned, some of the tiles get stuck and I have to push on them harder to get them to move. I can usually get it to go eventually, but some of them are stubborn.Love this game a lot and can’t wait to love it more!!
Developer Response
Thank you so much for the kind words and for enjoying dotio so much!Both issues you've raised have been addressed in the latest update (1.4.7):1. Expert puzzle repetition; you're right, the puzzles aren't randomly generated, they're all hand-crafted with unique solutions. You've likely played through the entire Expert catalogue (impressive!), so the game was cycling back through ones you'd already seen. I've improved the selection logic so you won't see recent puzzles repeated, and I'm starting to create more Expert puzzles to expand the pool. You can expect these in the next release! 2. Stuck tiles; I've found and fixed several issues where drag interactions could feel unresponsive. Tiles should now respond cleanly every time!Thank you so much for flagging these. Feedback like yours genuinely shapes how the game improves. Hope 1.4.7 feels better!!
Just like pips
blahblahmmmmm
Love it
