LONDON (CNN) -- How many points does a Scrabble player get for spelling "hernia?" That question won't be answered here, but don't worry about these brawny British soldiers. They seem to have a good grip on things as they move giant-sized letter tiles during what was billed as the world's biggest Scrabble game.

The playing field -- and it really was a field -- covered most of London's Wembley Stadium, a place where competition usually means a soccer or rugby match.

Using letter tiles the size of dining tables, various teams comprised of some of Britain's best Scrabble players commemorated the popular American-invented board game's 50th anniversary.

Here's hoping a "triple word score" comes their way.
