Wordsearches used to be the easiest puzzles in the world. They were the puzzle for people who didn't want to be too challeneged in their free time. Far easier than crosswords, wordsearches would provide limited fun but plenty of satisfaction (because they were so easy). Some wordsearches even had the words which made their solution printed below the puzzle - to make them even easier.
NJ Software, makers of Spellbound, clearly thought that all this had to change. What they have produced in Spellbound is a mixture of the traditional wordsearch, a bit of Boggle's flexibility, Tetris style moving blocks and a time challenge.
Spellbound's curious mixture of these ingredients makes it an original game which really does challenge you to move quickly. As your skill increases, you can move from the Easy skill to medium - which imposes a time limit. The key to the game is to avoid thinking too linearly: look for letters which go together even if they're not next to eachother.
