Abstract: Prismatic blocks having a triangular cross section are provided with letters and scoring numerals on two faces thereof. In forming words, the players position the blocks in a grid having rectangular openings therein so that only one of the lettered faces is visible. The scoring numeral on one face of each block is contained in a box, whereas the scoring numeral on the other lettered face is unboxed. The highest score wins the game. However, the players can earn extra or bonus points by combining the blocks in prescribed patterns, such as words of at least a certain length containing all boxed numerals or all unboxed numerals.
