Glad to see the update for iOS 11 BUT my scores are now all screwed up so what you gotta do is delete the game and reinstall. You lose your scores but they're beyond repair anyway. **Developer response:** 9 years later I’m here with 6.0, I made sure to test score migration carefully so we don’t have any repeat mistakes! Thanks for your support. ### 5/5 — Great App *2017-09-26* Great app, nice to see it still going strong in 64bit. **Developer response:** I've updated the game to support iOS 11. Thanks for your support! If you run into any new problems feel free to email me: jacob at omgpanda dot com ### 5/5 — A favorite casual game! *2015-11-02* One of the first games I ever downloaded to my very first iPhone. Simple and relaxing. This one has been ported to each new phone and I keep coming back to it. Great for a few quick moments of stress relief. ### 5/5 — A great puzzle game that will stay fun for years! *2015-07-26* A great puzzle game. Played it for years, and it is still fun ### 5/5 — Simple, but the best *2012-09-11* This is the game I always come back to. It's in my home row and the one I turn to whenever I'm bored. Stellar, simple game mechanic that gets challenging fast. ### 4/5 — Fun! *2009-11-13* Pretty dificult game. You need lots of attention to play. Reccomend coffee before playing! Your eyes will hurt lol ### 5/5 — Awesome game, challenging and fun! *2009-10-13* The game has you stacking block sequences in an isometric view as you try and eliminate blocks, or even get combos. That would be standard fare for this genre, but where it gets crazy is that the game slowly adds more colors into the mix, making it harder to get eliminations. Also, they added a global scores feature so you can rank yourself worldwide (if you're good enough!) and see the top 100 at any time. Really fun!! ### 5/5 — Outstanding *2009-09-20* I had to delete the app because it's like crack. ### 5/5 — I like it better than Tetris *2009-09-06* I have both Tetris and iso, and I have grown to like this game more. The fact that you're matching colors horizontally, vertically and diagonally provides more opportunity for strategy. The pace is pleasant. The bricklike sounds give the game a tactile feel. I come back to this game again and again. And it's inexpensive too! ### 5/5 — Fantastic! A Must Buy! *2009-08-21* I am addicted to this game! As an avid gamer, I am always on the lookout for new and exciting new games and "iso" delivers. Growing up in the Atari/Nes era, I was immediately drawn to the graphics. As a fellow iPhone Developer, I understand how difficult it is to make a high-quality game and "iso" very polished. The sound effects are perfect and I can see myself playing this game for weeks. "iso" is easily worth twice the current price and rivals the more expensive apps. Thank-you to the developer for giving us this gem! ## Frequently asked questions about iso ### What is iso? iso is a classic falling block puzzle game where you match falling blocks by color to clear them.
