To comprehend the meaning of the sentence "He played his wife false by inviting his mistress to the house as his cousin," it's essential to break down the phrase:

The key expression here is "played his wife false." The phrase "played false" commonly means to be deceitful or unfaithful. In this context, it indicates an act of betrayal or cheating on one's spouse.
