This App takes Sudoku to the third dimension in your brain. Simple rules but hard to master. Exactly as a good puzzle should be.

5 sky scrapers with 10, 20, 30, 40, and 50 stories stand in each row and each column.
The numbers at the border indicate how many sky scrapers can be seen from this point when looking at the row or column.

Uses the basic rule of sudoku and adds a third dimension resulting in a mind crunching game.

- Auto Save: continue your game where you left off later
- 4 different pens so you can jot down your thinking
- additional functions to clear the board or to fill in penciled in numbers
- use of the Retina display of the iPhone 4 to the fullest
- incorporates Apples iAd

Try it out - either as an alternative to Sudoku or to help you work out your brain muscle. With iAd Support its even FREE!

If you like it, you can get the iAd free version in the AppStore.
