User Reviews
Great game. Only reason I have 4 not 5 is my greediness about an already great feature. Seeing the past results of past games is great. But why only the last few games?! Would be more fun with a deeper past. Games too good. Had to give 5 stars anyway
Companion app for the board game. Does its job well, and I find it more convenient than a sand timer.
Why is there no visible timer?
Timer not visible??
