A Scrabble variant, published in Israel in the 70's (guessing). In this version, plastic letter tiles can be connected three dimensionally, so words can be formed vertically and horizontally, creating a 3-D 'sculpture' of words.Letters have values as in regular Scrabble. Double word score is given for a word on a 'new' dimensional plane. Triple word score is given for a word that 'breaks' across more than one plane, by connecting existing letters.Simple, yet has some depth to it. The game comes with 100 letter tiles and 20 special connectors that allow the structure to hold itself up. No board is needed. - BoardGameGeek
