The term slot is sometimes used to refer to a certain area of the machine in which a winning combination will appear. For example, some slot machines have extra symbols that can be triggered to increase your chances of winning. Others have multipliers that can double or triple your winnings.

Once the slot game is developed, it must undergo testing and QA to ensure that all aspects of the game work as expected. During this process, your team will perform Unit Testing (testing each component individually), Integration Testing (combining the components together) and System Testing (testing the entire slot game to determine if it meets the technical, functional and business requirements). Thorough testing and QA result in fewer bugs and glitches.
