Nut n Bolt Sort: Color Puzzle

I started playing this on my phone and loved it so I payed to get rid of ads, they actually have a reasonable price compared to others. I decided I wanted a bigger picture and downloaded it on my iPad. They automatically restored my no ads purchase which was great, but the game is different and I’m confused. I don’t necessarily mind the change but I’d like the option to make it. On my phone the game, even the super hard levels are just moving the screws to create the picture and thinking enough ahead so you don’t run out of moves. My iPad started that way, then right in the middle of a level it changed so that some of the screws are covered and you have to wait for them to get uncovered in order to use them. I’ve played nut and screw games like that before and they’re fun, but I’d like an option because there must be one since my phone isn’t that way and my iPad didn’t start out that way. I’d really just like to know what’s going on with this game. Even the pictures they show on their game page are essentially the same, no locked screws. As I said I like that kind of puzzle in the right mood but is there a way to toggle back and forth?

I really like this game a lot. I like that there is no timer. I enjoy being able to take my time and just enjoy sorting the bolts. And the number of ads is reasonable. There are a few things though that I would change if I could. I wish you could zoom out on the picture to be able to see the whole thing at once. I get a little tired of having to swipe around to search for the bolts I need - this is only a problem on the large puzzles. The other thing I would change is to be able to see the finished puzzle. As soon as the puzzle is finished it disappears. I don’t think the game saves the completed puzzles. At least I can’t figure out how to retrieve and view them. And one last thing that I don’t understand is the hint button. I can’t figure out what it does. I hit it when I need a hint and it doesn’t do anything but count down some numbers It gives no hints. So on the really large puzzles ( especially when there are a couple colors that are too similar for me to be able to distinguish- I have ended up with no way to complete the puzzle. This can be frustrating when you put in all that work to complete it and you end up right at the end and can’t find the last bolts.

I’ve been playing this for the past few months and I do love it very very much out of all of the nuts and bolts games I’ve played but I have completed every level including the challenge ones. There are no new levels. I’ve realized after a while the pictures just repeat itself which is no fun considering I’ve probably played the same picture a bunch of times and I know what to expect. The challenge levels should have more pictures I’ve finished everything and I would like there to be more new pictures to complete. I’ve been waiting for a few weeks now to see if they add any new pictures and they haven’t. I think I will be giving this game a break for a while until new pictures have been added. Also one or two of the challenge pictures I did not complete (either phone died or just exited out of the game) and it will not let me finish it. I don’t know if that’s a glitch or bug or just how the game is but I would like there to be an option to be able to go back and finish those pictures.
