One of my personal favorites, this game is one of the top 5 most popular free online games on MSN. The game Text Twist is also one of the most popular iPhone and iPad apps as well. It is a simple game for all ages, especially seniors. Easy to see, high contrast interface, with levels from easy to hard. It is addicting and fun, and challenges the mind at the level of the user by allowing the player to find 3, 4, 5 or 6 letter words from a 6 letter jumble. The three letter words are more plentiful than the 6 letter words, but all correct choices get points and an immediate reward for the player. The words and variations become more difficult the more letters in the jumble. I has pleasant sounds as feedback, and takes very little training to use it. Hours of fun await you, and you might just "warm up" or sharpen your brain by playing the game. I highly recommend this one.
