Blue Block is an entertaining puzzle game where your goal is to arrange the blocks on the board in such a way the dragon can reach the indicated destination. The app provides you with dozens of challenges, is suitable for users of all ages, and keeps track of your highest scores.
You have access to 9 packs of levels: Kids, Easy, Medium, Hard, Expert, Crazy, Medium Double, Hard Double, and Expert Double. The Double groups of missions bring you two special blocks which need to be guided to their destination, while the other packs offer you only one dragon block.
A good thing is that, if you haven't played this type of puzzle games before, you can practice your skills by playing the Kids challenges. The app offers you detailed gameplay instructions and teaches you how to complete challenges with a small amount of block moves.
The trial version of the game gives you access to a limited amount of levels. However, if you acquire the full app package, you will be able to play up to 39963 levels, each with a different block layout.
Another advantage is that you can always replay missions and increase your high score.
The one thing that might bother you is the lack of hints. Personally, I think it's better not having access to hints as it makes this game even more challenging than it already is.
In conclusion, you should acquire Blue Block if you're into solving brain teasing puzzles on your spare time. The app has nice graphics, automatically saves your gameplay progress, and comes with an affordable price.
