I get bored easily if a game is too easy or more challenging, it seems that there is no way to overcome it. The Istry are great puzzles to kill time. It is quite easy for anyone to play. The challenge is to overcome the best time or the highest points of the board. Or simply challenge yourself to overcome your own scores. There are enough different puzzles that if I get bored with one, I can move to another. Many puzzles or you can choose to subscribe. I have many game applications on my phone that I forgot how much I like this. Very good touch controls. I have disparaxia and I generally have difficulty with this type of games. I love you and I can do them intellectually, but for the screen to register where I made my touch it is usually impossible. It is not so with the isutys. I am very impressed that I can select cubes where I can see only the smallest piece. This incredible puzzle should not be surprised, this incredible puzzle should not be lost! The various modes for cubes add to fun. My only complaint and a minor is that you cannot "deselect" a mosaic you don't want to use. But in general, this is an exceptional game and can become a classic. Really great, it has many of the Istry games for free, including a redesigned Halloweenistry! (I bought the 2 Halloween districts and 2 of the others). My only complaint is that it is difficult to see/play on a small phone screen. I love music and various highly detailed funds 3-D as well. From the last update, the application only shows a black screen. LG G7 Android 9. I love playing this game !! Before, you had to download a different application for each game, but now they are all in one game! I love the 'new' istrys. I just can't see pay much for the full version. I have a limited income every month, so I can't pay what he wants for everything. Too bad ... I would like the 'free side' to have more different applications (elements), to choose from. However, I love the game. Keep up the good work!!!
