In terms of slots, Greentube has brought a number of interesting reel systems and payline types. For example, the AllPay variant has no payline at all, opting to make players aim to land three matching symbols across three reels. The platform also offers a powerful selection of marketing and player retention tools, including missions, tasks, progress bars and coins. These currently apply to the social gaming aspect only, but it would be an exciting move to see them come to real-money games.
