although I doubt whether the OP is really a game developer or not, what is certain is that I'm just trying to respect other people's opinions.
more precisely the OP was just asking for advice from gamblers here what kind of game they want and with what features.
so the OP asked everyone who loves to gamble more advice to express the interest gamblers want.
on the other hand the OP might as well have done some research as @Fivestar4everMVP said to develop a game that many gamblers out there love and are interested in.
so it's not because of the OP a developer should always develop games with his own mind. but it is natural for developers to ask questions and seek advice from customers to provide the best advice in developing games with a large audience.
Conducting surveys has always been a way to find out what the people think or want, and when it comes to developing games or applications for based on public interest, asking a community about what they like and which kind of games they would like to play is a good practice for developers to be able to create games that will already be of interest of the public.
This way, they won't need to be worried about what the reaction of the public will be for the games that they've developed since they already know that the games will be liked since they are based on the interests of the public collected through the survey conducted earlier.
But of course, it is possible and useful to conduct a survey, but it is far from always possible to understand what is right to improve.
There are many proposals that preclude concurrency in development. For example, some people write that it is necessary to make the button on the screen bigger and to the right, and the same part writes that it is better to place it on the left and make it smaller. And then what to do! This is generally incomprehensible. Of course, when 80-90% of respondents agree with the change and refinement of the interface, this should be implemented. But changes to improve the game for the user are not always so obvious.
But it is precisely to clarify such obvious changes that it is very correct to conduct a survey.
