When you land on the Beer Time row you immediately move to the one of the holes in the top corner and you lose counting points 3 times. This includes pegging and hands, each time you miss counting points you move your peg down 1 peg hole. Once you are back on the track counting resumes as usual.
If you land on the Goto Jail sign you must immediately go to Jail. If there is more than one Jail then you go to the closet Jail behind you.
