Originally, Upwords was played on an 8×8 square board, with 64 letter tiles. Hasbro Europe later expanded the gameboard to a 10×10 matrix and 100 tiles, to accommodate the longer words frequently used in other languages such as German and Dutch. The 10×10 matrix is currently employed in worldwide versions of the game. The board is purposely smaller (has fewer tile positions) than Scrabble to encourage and even force the stacking of letters. It does not have special squares that require additional scoring calculations.
