The world of slot machines is a thrilling realm of flashing lights, spinning reels, and the excitement of winning big. Whether you're a seasoned player or a newbie trying your luck for the first time, understanding the various buttons and controls on an IGT slot machine is essential to enhance your gaming experience.

Detailed Overview of Controls and Functions

Spin/Play Button

The Spin/Play button is undoubtedly the most crucial control on any slot machine. As the name suggests, pressing this button sets the reels in motion, kickstarting your chance to win.  Once you've placed your bet, simply hit the Spin/Play button, and the reels will start spinning, generating thrilling anticipation as you wait for the symbols to align in your favor.

Bet Per Line

The Bet Per Line button allows you to adjust the number of credits or coins you want to bet on each payline. You'll often find "+" and "-" symbols next to this button, allowing you to increase or decrease your bet incrementally. Back then, players had to manually insert coins into coin slots because coins were the only accepted form of payment for slot machines. So, choose wisely to manage your bankroll effectively.

Max Bet

The Max Bet option will take you to larger stakes if you're feeling really risk-taking and want to go all out. By using this option, the maximum permitted stake is immediately placed on all active paylines. Similarly, it's a quick and convenient way to ramp up the excitement and potentially win bigger prizes. Just make sure you're comfortable with the increased risk, as the Max Bet button doesn't hold back!


For players who prefer to sit back and enjoy the action without continuously pressing the Spin button, the Autoplay feature is a game-changer. When Autoplay is turned on, the slot machine will automatically spin the reels for a certain number of spins or until you manually stop it. Furthermore, this feature adds an element of relaxation to your gaming experience, allowing you to soak in the excitement without constantly pressing buttons.

What do the buttons on a slot machine do?

  • Spin/Play Button: As mentioned earlier, this button sets the reels in motion, initiating the game and determining the outcome of the spin.
  • Bet Per Line: The Bet Per Line button enables you to adjust your wager on each active payline, giving you control over your betting strategy.
  • Max Bet: When you're feeling adventurous or want to maximize your winning potential, the Max Bet button places the highest possible bet on all paylines with a single press.
  • Autoplay: By activating Autoplay, the slot machine spins the reels automatically for a predetermined number of spins, providing a hands-free gaming experience.

How Do They Control Slot Machines?

The buttons on the slot machines are how players interact with the game. Each button has a specific job, like starting the reels, changing the bet, or activating special features. The slot machine's computer is connected to these buttons and understands what the player wants to do, making the game work accordingly.


Just like when playing manually, the machine follows the player's chosen betting settings during the predetermined number of spins. This means players can enjoy the game without needing to keep pressing buttons constantly. Similarly, it creates a more relaxed and immersive gaming experience.
