What is the ruling on purchasing a website specializing in games that require payment to complete the game, what is the ruling on the money earned from it, and what is the ruling on visitors paying money?

If the game is permissible in itself, does not contain anything that violates the values and beliefs of Islam, does not instill a spirit of animosity or the usurpation of others' lands without right, and does not contain music or forbidden scenes such as nudity, then there is no harm in purchasing it and playing it. The seller is permitted to take its price. One must not be extravagant in playing.
