Make words, smash the tower, and set off chain reactions.
Drag across touching letters, in any direction including diagonals. Words need 3 or more letters. Let go to play it.
Played tiles shatter. Everything above drops down and fresh letters fall in from the top.
If falling letters line up a word reading left to right or top to bottom, it explodes on its own. Every chain step multiplies the points.
Rare letters are worth more (the small number), and longer words multiply. You get 10 words a day. Hit the β targets.
