A slot game is a casino machine that pays out prizes when symbols line up on a payline. Traditionally, slots were operated using coins, but in the 1990s and 2000s, players began to use credits instead.

The first step in developing a slot game is conducting market research. During this process, you interview customers to find out their requirements and preferences. This information helps you determine your business goals and budget.

You should also conduct a risk assessment. This involves identifying potential hazards, evaluating the risks, and implementing solutions to reduce them.

Before releasing your slot game to the market, it needs to be tested to ensure that it works properly. This includes unit testing, integration testing, system testing, and user acceptance testing.

Variance

The variance of a slot game indicates how often it pays out and how large the wins are. Low variance slots land small winnings regularly, while high volatility games offer big jackpots but pay out very few times.

Return to Player (RTP)

A slot’s return-to-player percentage is a key factor in choosing the right game for your bankroll. The higher the RTP, the more money a slot can pay out to its players.

Free Spins

A random feature that triggers a free spin bonus after a paid spin increases the chances of winning without paying extra. It also makes the game more exciting by giving you the chance to win a larger prize.

After determining the technical, functional, and business requirements for your slot game, you should begin developing it. This includes the design of the game, its graphics, and audio. During this process, you also need to include important features and bonuses that will make your slot stand out from the competition.
