Slot is a game in which players spin reels to land symbols on a pay line. Winnings are based on the number of matching symbols and the amount of credits won per winning line. In some machines, such as progressive slots, a portion of the player’s wager contributes to the jackpot, which can be worth millions of dollars.

To play a slot machine, the player inserts cash or, in ticket-in, ticket-out machines, a paper ticket with a barcode into a designated slot on the machine. The machine then activates a lever or button (physical or on a touchscreen), which causes the reels to spin and stop. If the symbols match a winning combination on the pay table, the player receives credits based on the size of their bet. Symbols vary between machines but typically include fruits, bells, and stylized lucky sevens.

In the earliest stages of slot game development, your team conducts market research to understand how much your potential customers want to spend on a game. Based on this information, your team can develop a prototype or minimum viable product (MVP). A prototype is a lightweight version of the full game that allows your business to test its concept before investing in its development. A prototype also enables you to identify the technical and business requirements for your slot game. To create a prototype, your team must produce sketches, wireframes, and mockups to display how the game will look.
