Your Morning isn’t starting out great. You woke up very nearly dead. So did everyone around you…also…Grim is here to take you from this life to The AfterRealm.
Fortunately, there is a way out. You and the other players around you have one chance to escape the Grim Fate that awaits you on the other side…you must defeat one another…and then Grim himself…at a game of his very own making.
GRIM is a "Roll For Your Life!" dice game that is simple to learn and fun to play.
