3 stars: This is missing some useful features to really make this a good app. However, it is playable and hashi is a fun game to begin with. I appreciate the sheer volume of puzzles that other apps with more usable features may not have. So, I guess this app is fine. Nothing great, but it'll do if you're really jonesing for some hashi puzzles.
4 stars: Please make it possible to highlight any island by long-tapping on numbers. Having to check manually if islands are connected is very annoying. Also all puzzles are exactly the same difficulty, so categorizing them as easy-insane instead of small-huge seems a bit illogical. EDIT: Yes, sorry, I forgot numbers themselves are called \
5 stars: I fell in love with bridges after finding it in Simon Tatham's puzzles, but the ones generated there were too easy. Since I use a tablet, this app can generate heavy and insane puzzles that give me a longer playtime. I also love how it shows if islands have enough bridges. Overall an amazing app for an addicting game, it gives a rush of adrenaline once completed!
4 stars: Agree with other reviews. Much too easy--hard games aren't any harder than easy ones, just larger. Also the very first game I played had two possible solutions. Otherwise a nice interface if you're just looking to get your Hashi on. If you're looking for a difficulty curve done right, check out Conceptis.
5 stars: Very good and simple (in the rules) game. Easy to learn, harder to complete. It's good for keep...
