Gamesys is an online games software developer, founded in 2001 and based in London. They have over 300 employees and are responsible for providing the software for around five online bingo sites, including Caesars Bingo and Sun Bingo. They are also behind the development of Virgin (Games) Bingo.
Their sites are all custom designed, so they tend to vary quite a bit from each other, avoiding the homogenous styling of some of their competitors. They are all well-constructed and easy to navigate and play, providing few difficulties for new or inexperienced players.
So overall, do not be fooled by their apparently tiny portfolio. They are a relatively large company in their field, providing the software behind some of the most popular sites in online bingo. Gamesys sites are well worth a visit and theirs is a name you can trust.
