Love math? Love sudoku or math based puzzles? You won't be disappointed by this game.
Player will see that this game has nice touch of nature while progressing through it. The game is divided into regions - based on nature like, ocean, sky etc. Each region has multiple sub-regions which has plenty of puzzles to solve. More than thousands of puzzles are there for you to be solved. Each puzzle has some pre-defined par steps under which you must solve that puzzle. I don't think any average IQ person will find it difficult to match that par steps.
Not all puzzles are same - difficulty levels will also rise as you progress but I didn't find that any puzzles are really that much challenging.
If you fear math? Then also you'll find this game beautiful time pass. Go get it.
