Best 2048 edition for iPhone and iPad

Astonished with update that game modes are locked but thanks to developer as he is not charging a penny for unlocking i used to play only 2048 before now I will try next mode and I think it will be easier as there would only 26 alphabets finding "Z" is the final destiny
So another Great puzzle game with unique features and interesting game modes to play I enjoy them and also elements mode is a learning way too for knowing universal elements discovered yet
Colourful themes also fascinate me while playing the game Specially love playing with the default Sienna Red theme its looking coolest of all with 7x7 board
