Abstract9 is a modern take on classic 9-letter anagram games. It features three options of game play: using a key letter, a hint to the 9-letter word and time limits. These options are available to registered users. Registered users can also enter 9 letters to find the working list of words that can be made with those 9 letters. Unregistered players will have the game decide which of the rules will be applied. Enjoy.
