What is the name of an old German peg and dice game with a 6 hole board in which you try to get rid your by rolling number on that empty...1-5 or open hole?

The game you're describing is called Kniffel.

Kniffel is a German dice game that is very similar to the popular American game Yahtzee.

Here's how it works:

* Board: The game uses a six-hole board (like Yahtzee) with categories for different scoring combinations.

* Goal: The objective is to score the most points by rolling dice and filling in the categories on your scorecard.

* Gameplay: You roll five dice and try to get combinations like three-of-a-kind, four-of-a-kind, full house, small straight, large straight, chance, and Yahtzee (five-of-a-kind).

* Scoring: Each category has specific rules for scoring, and you can choose which category to fill on each turn.

Kniffel is a fun and challenging game that is popular in Germany and other parts of Europe. It's a great game for families and friends to enjoy together.
