The whole concept is fucking stupid honestly cuz one bad roll can mean you'll miss a chalice & have to start over from the very 1st tile. I'd rather do boss fights over & over again instead.The only impossible route is the balance route. currently there is a you win and she wins route. balanced route is not yet implemented because it is unfinished. author said he will add it in a future version, at which point you could get equal number of chalices
Whoever came up with this maze monopoly shit probably gets off from choking cats or something cuz this is more torturous than doing a no damage run on dark souls at the hardest difficulty.
