Search for words in the jumble of letters. Words are created by selecting adjoining letters. When a word is found it's letters are removed from the board and new letters drop into place. Special words give you rewards to make it easier to get more words. Palindromes (words that spell the same word forwards and backwards) give you a blank. Blanks can replace any single letter in a word. Half-palindromes (words that spell a different word backwards) give you a swap. Use a swap to switch places of two words. There is a secret word. Find that word and you get a bolt. Bolts will remove all the letters of one color. Each level has a different goal. Complete that goal to move to the next level.
