Upwords

Upwords is a board game invented by Elliot Rudell and published by Hasbro Games (a subsidiary of Hasbro). Upwords is similar to Scrabble, except that players can stack letters on top of other words to create new words. The higher the stack of letters (up to five) the more points are scored. This often makes words built in later turns of the game more valuable than earlier words, increasing play intensity.
