Number Chef update 1.4 is now available for Android.
This update brings two major improvements to the gameplay:
Move preview
Drag a tile all the way over another tile to see the result of the calculation! This helps to eliminate silly calculation mistakes. Don't worry, the game still won't be too easy after this. :)
Dynamical UI zooming
See before and after. The new version dynamically checks the size of the gameboard in each level and adjusts the size accordingly, making it easier to play especially with small screen mobile devices.

iOS update coming soon!
