If you want to create an effective website or a slot game app that people will be downloading and using, you need to do some serious research about your target audience, its wants, needs and desires. The worst thing you can do with a website, any website, not just an online casino or a slot game app, is to try and be all things to all people.
It is the worst thing because this is something impossible to accomplish. If you think about the most successful companies on the planet, you will realize that they are about something, both technology companies and traditional brick-and-mortar businesses. For example, Google became successful with a very simple landing page because it is for people who want answers here and now. They do not want distractions or beautiful pictures. They want to type a question or a search query and get a result. Apple is for people that appreciate great design. The company spends a lot of money to make sure that its products look great and are convenient to use. This is very different from trying to make a product that is just efficient or effective.
Even in the offline world, you will see examples of companies that pick their niches and stick with them. McDonald’s is an example of such a company. McDonald’s doesn’t try to be all things to all people. It doesn’t promise the best food. Virtually in any town on the planet, you can find a burger that tastes better than one from McDonald’s. However, the company is extremely successful because of two things: predictable quality and speed. Customers know what they are going to get, and McDonald’s gives them exactly what they are looking for. Not the best-tasting burger, but a burger of predictable quality quickly.
Your online slot app should be similar to that. You need to find out what your users like and give it to them.
