Delta: It's All About 4: free puzzle app game for iphone, ipad

     

Case Ertel is the author of Delta: It's All About 4.  Seems like another version of Threes!  But it' not.
The idea is to fill the screen with 4's.  You can combine adjacent numbers. Or you can split a number.

      

This game goes pretty fast.  A few levels are pretty tricky, like #81 which I needed extra moves.   Unfortunately, there is no way to go back and select any previously done level. At the moment, I'm stuck on 110. Which I think is impossible.


Each grid size is 2x4. Which is a shame because after a while the puzzles become too repetitive.  Maybe the grid size changes, but there's no way for me to find out.....unless I keep doing them.


Here's another thing that bugs me: when I select next puzzle, why do I have to then click 'play'?


Some things that work well: good graphics. Good concept.


Overall - play it only to see how fast you can solve them.  If you manage to do even 300 of the 1000, please contact me and explain if the game gets any better.
