  • Patent number: 5615886
    Abstract: A gameboard has a crossword grid with bonus spaces of different values marked in different color indicia indicated on an adjacent key. A chip set includes basic chips having a single letter and corresponding numerical value marked thereon and enhanced chips each having a plurality of regions with respective different letters and corresponding numerical values in respective regions marked thereon for alternative selection to complete words on the grid. The bodies of the chips are transparent so that underlying indicia can be seen therethrough. In an alternative, the chip bodies are colored so that the scoring color seen through the chip will be changed to a third color when a chip of a first color overlies a space of a second color. The colors of different regions of an enhanced chip can also be different providing different scoring values according to the letter selected.
