Quick Monster Casino Overview
KCB’s Selection Method for Monster Casino Sister Sites
Our criteria for selecting the best Monster Casino sister sites were very strict, and we followed the same rigorous protocols for all our selections and reviews. We looked at several factors for each and every casino site before we compiled a list of all the best sister sites. The criteria we took into consideration are as follows:
- Company background: We looked at the history of the company that operates all these casinos and how long they have been in the works. This helped us derive the company’s values and how those are transmitted to the casinos.
- Games portfolio: We also ensured that all the casinos we tested offered the best casino games from reputed providers. The selected games were played using real accounts, which our experts used to test all the casinos.
- Payment methods: The availability of reliable payment methods is a huge factor for UK punters, and we took this into consideration while reviewing Monster Casino and its sister sites.
- Available bonuses and promotions: Bonuses are a great way to keep punters engaged with an online casino, and these sites have them in abundance. We studied all the bonuses these sites offer in 2024, from the first deposit bonuses to bonuses offered to new players.
- Customer support services: We measure a casino’s customer support system by how its agents respond to customers’ queries and how helpful they are on live chat. Monster Casino and its sister sites were also tested on this, and we were fairly impressed with what we experienced.
