Holy Bread need several clicks every 5 do 15 minutes, depends on how long the quest is. Nothing major. It's the easiest game of the lot.
Cryptobrewmaster demands even less since the tasks are longer. It might be that I stand corrected on which game is the easiest :)
I have all four open all the time and click through them during work breaks ...
I've started on Cryptobrewmaster, with your link. Will see how it goes.
Thank you!
