Recently, many game programs have been developed aggressively as hardware on field programmable gate arrays (FPGAs) because of the extremely large solution space of such games as the Connect6 game, Blokus Duo game, and others so that the computational capabilities of computers are currently insufficient to search all possible solutions. This report describes an FPGA acceleration experiment for the Blokus Duo game. The FPGA Blokus Duo Solver was implemented on an Arria II GX FPGA (Altera Corp.). Its operation speed is 25 times faster than C++ based software operation of the same algorithm on a Core i7 processor.
