We are looking to implement a rating system for our casino games for our users. The rationale being that the more popular a game is with users, the more others will play it, thus encouraging them to choose a game quicker and encourage play the more popular games and increasing the conversion for us.
We need the user playing a game as quickly and as effortlessly as possible, the quicker a user chooses, the faster the conversion happens.
We have narrowed it down to 2 options:
Like/heart with a total number of likes next to it. Gives a numerical total as to how many people like the game next to the heart icon.
Star ratings. A user is able to rate a game out of 5 stars.
The question is what is the best rating system to implement? Are there any criticisms of each system?
