How to Play Spell Tower in Rush Mode

The time pressure of Rush mode is what really makes it work for me. The tiles with the requirement numbers so the tile that kind of has to be used in a word longer than four or five or six length is such a key feature of the game. These things like words longer than five destroying tiles around it or requirement tiles, these little things that came up solutions to solve problems. I don't know what it is about it it'skind of to me like a 21st century crossword puzzle or something that's not quite right but it just feels like such a natural fit for the mobile platform.
