A simple word game in which you are required to make as many words as you can from what you're given, which is nine letters, but you must use the middle one in every word. It's an old, old game that a lot of players must know already under different titles. It's been here in its online version for a few years too.
Presentation is basic but it all works fine. You can add your name to the scoreboard if you do well in the puzzle of the day, and you can register so that you may continue the game later from any computer with a browser. You have 24 hours to finish the puzzle before it expires and a new one appears, so it's ideal for beginners and experts alike. And you can polish your skills non-competitively on previous days' puzzles. Good, harmless fun.
