I tried many different bgm games but this was best I could find. I enjoy challenge & playing at "hard" level was just that, no lame moves by computer opponent. Dice roll sound effects good, board aesthetically appealing, & options (I never play with music) acceptable. Only negative is "glow" to highlight moves is a bit cheesy. Its also good that touch-move responsive & one can move pip by number specified on both die with single touch.
