Quad Doku is a tile-laying word game played on a 4x4 grid with a 2x2 hole in the middle. Players take turns laying tiles with letters on them to form four 4-letter words around the frame, with the goal of making a doku, a four letter word whose points add up to 10.
The game is much like upwords, in that you can place tiles on top of the tiles already on the board, but different in that each letter is worth a number of points; sometimes the same letter has different point values on different tiles.
From the publisher: The challenging word game of four letter words! Play with letter tiles on a matrix of four intersecting words. the goal is simple, just form as many "dokus" (4-letter words) as you can. Score four dokus on one turn, and you've scored a perfect Quad Doku!
