Jitters is a timed word game where players draw cards with pre-arranged crossword puzzles on them. A player starts the timer and then rolls 'lettered' dice and must use the face up letters to fill in the crossword with qualifying words before time runs out. Each crossword puzzle card has a point value that increases with the card's difficulty. This game is somewhat stressful as you must think quickly, making words to fit the blanks on the card...of course when the timer runs out making a loud smacking noise as you were about to finish your last word - you jump every time... - BoardGameGeek
