Slot is a game that offers fair rewards to players to keep them coming back for more. It also has to be simple to play, so that users are entertained.

At this stage, your team should come up with initial sketches, wireframes and mockups of the slot game. Once the artists are done with these, your developers will start creating a prototype or minimum viable product (MVP). The MVP is an initial, lightweight version of the slot game that allows your business to showcase the basic game mechanics and features to everyone involved in the project.

The earliest slot machines were coin-operated devices that paid off winnings by displaying symbols on a screen, after the player placed a coin or paper ticket into a machine. Later electromechanical devices incorporated reels and a lever or handle for operating the device, and allowed for many new payout schemes, including progressive jackpots. Video slot machines, which use a computer to select and display stops on a monitor, have replaced mechanical devices in many casinos.

Casino managers know that keeping slot players happy is key to maximizing casino profits. They are therefore eager to lower the house advantage, but fear that raising the price of a spin will cause players to walk away and play at another casino. To reduce the cost of a spin, they can increase the number of possible outcomes on each reel or add special symbols that trigger different bonus games.
