A more thorough explanation:

A hazarder (also spelled hazardor) is a person who plays an illegal game of dice.

For example, in the past, some people would gather in secret to play games of dice for money. These games were not allowed by the law, and those who participated in them were considered hazarders.

This term is not commonly used today, but it was more prevalent in the past when gambling was not as regulated as it is now.

The examples illustrate that a hazarder is someone who takes part in an unlawful game of dice. It is important to note that gambling laws vary by location and time period, so what may be considered illegal in one place may not be in another.
