(WAFF) - Wordsmiths and lovers of letters also have a love for the world's best-known crossword game, Scrabble.
Born out of the Great Depression, the game, invented by Alfred Mosher Butts in 1929, has gone through countless evolutions and formats, spawning online games, tournaments - even a few TV game shows.
There are countless numbers of words you can make with your Scrabble tiles before the bag runs out - but not all of them are acceptable, according to the official Scrabble rules.
Proper nouns are off-limits, as are abbrev. (abbreviations), prefixes and words requiring apostrophes or hyphens. That means "off-limits," used just a moment ago, would be... well, off-limits.
That cuts out a lot of options; so what do you do when you have just a few tiles left, but none of them seem to make a really cracking play?
