A slot game is a casino game that requires the player to insert cash or, in ticket-in, ticket-out machines, a paper ticket with a barcode. The computer inside the machine then activates reels that spin and stop to display symbols. When a winning combination is triggered, the player earns credits according to a pay table. Symbols vary depending on the theme, but classics include fruits, bells, and stylized lucky sevens.

Before a slot is ready for launch, it must undergo testing and quality assurance (QA) processes to ensure that all components work together as intended. This phase of development includes unit testing, integration testing, system testing, and user acceptance testing.

During this stage, your artists produce initial sketches and wireframes for the game. This is the best way for your team to see how the game will look and function. You should also test the game for bugs and other issues that can impact the overall quality of the product. During this phase, you may also decide to add additional features to your game, such as free spins or multipliers. These features can significantly increase a player’s chances of winning without paying extra.
