Upwords

Upwords, recently renamed "Scrabble Upwords" by Hasbro, is a board game invented by Elliot Rudell and originally published by the Milton Bradley Company (which is now a division of Hasbro). The game is based on Scrabble, except that letters can be stacked on top of other words to create new words. The higher the stack of letters, the more points are scored. This often makes words built in later turns of the game more valuable than earlier words, increasing play intensity.
