Attractive and convenient bonuses
Every online casino tries to attract visitors with promotions in the form of bonuses. The correct use of bonuses can significantly help a regular player reduce the costs of his hobby. Some players even solely focus on bonus abuse to reach a long-term profit.
If you are a player in a casino, it is good to find sense in the tangle of bonuses and their requirements, even if bonus abuse is not your goal. While with some bonuses it's always beneficial to accept them, others have such unfavorable conditions set that it's simply not worth it. An example is a deposit bonus, where wagering requirements apply to a deposit and a bonus amount together. With high wagering requirements, this bonus will unnecessarily limit you in your bets and also in not being able to withdraw your winnings until you meet the wagering requirements.
Easy to navigate and graphically pleasant website
The website of an online casino creates that famous first impression of the casino, but it also influences how much will you enjoy playing in it. Of course, you can also play in a casino with an opaque and poorly functioning website, but it's not as enjoyable.
The rule of thumb is: big casinos generally have highly developed websites. The web design of a casino can become a place for competitive struggle between casinos.
Worse looking websites may suggest a low budget, a starting casino, or a weak IT team. But certainly do not make a definitive opinion about a casino from your impression of its website.
