Using your parents' credit card to make purchases without their consent is unethical and may constitute a legal infringement. In most countries and regions, unauthorized use of someone else's credit card is considered credit card fraud and may result in serious legal consequences, including fines and criminal liability. In addition, this behavior will also undermine the trust between you and your parents. If you want to buy games, it is recommended that you communicate with your parents and obtain their consent and support. You can also consider the following ways: 1. **Earn your own pocket money**: Save up the funds needed to buy games by working part-time or completing housework. 2. **Use gift cards**: Sometimes parents are willing to support your interests by giving gift cards. 3. **Look for free or discounted activities**: Many game platforms and apps regularly offer free games or discount promotions, and you can wait for these opportunities to make purchases. Respecting parents' financial management and decision-making helps to build healthy family relationships and personal integrity.
