In the video game industry, slots are a type of casino game where players place credits or, in “ticket-in, ticket-out” machines, paper tickets with barcodes, into designated slots and activate reels to spin. The machine then displays symbols and pays out credits based on the pay table displayed on the screen. Symbols vary from machine to machine but commonly include fruits, bells, and stylized lucky sevens. Most slot games have a theme and bonus features that align with the theme.

The process of building a slot game starts with market research, where businesses analyze the competition and potential customers’ preferences. Companies can also conduct a feasibility test, which helps them determine whether or not their new game will be successful.

During this stage, artists start creating sketches and wireframes to showcase the initial look of the game. Then, they build a prototype, or minimum viable product (MVP), which is an early version of the slot game that includes key features like the game mechanics and slot game design.

After the prototype is ready, it’s important to conduct thorough testing and quality assurance to ensure that the slot game functions properly. Testing can include unit testing, integration testing, system testing, and user acceptance testing.
