If you find yourself with the low-scoring tiles ADEILOR then words such as RAIL, LOADER, or maybe ORDEAL can be found. But it is only with a more specialist Scrabble vocabulary of seven- letter words that occur with common letters that you might be able to play DARIOLE for a 50pt bonus.
These are darioles, and that was one paragraph from the 163-page e-book, The Scrabble Player's Handbook, written by some of the greatest Scrabble geniuses of our time. Click here to download the book for free, or you could just play Scrabble on your iPad and use the "Best Word" function. [via]
