Look for casinos with proper licensing from reputable authorities such as the UK Gambling Commission or Malta Gaming Authority. Safe casinos use SSL encryption, have their games tested for fairness, and implement responsible gambling measures.

Most online casinos offer various payment methods including credit/debit cards, e-wallets (PayPal, Skrill, Neteller), bank transfers, and sometimes cryptocurrencies. The available options may vary depending on your location.

Casino bonuses provide extra funds or free spins to players. They typically come with wagering requirements (playthrough) that must be met before withdrawing any winnings. Always read the terms and conditions of bonuses before claiming them.
