Implementation Guide

To create this animated slot machine, we use a timer and a subroutine to create the animation effect. You must also add the Multimedia Control to produce the sound effects.

Adding Multimedia Control:

Click on Project in the menu, select Components, then select Microsoft Multimedia Control 6.0. Drag two Multimedia Controls onto the form and make them invisible at startup.

Sound Setup:

We use two Multimedia controls:

One for playing the spinning sound during animation
Another for the jackpot sound when a winning combination appears

Winning Combinations:

The slot machine recognizes several winning patterns with different payouts:

Combination	Payout	Example
Two matching symbols	$20 - $40	🍒🍒🍋
Three matching symbols	$200 (JACKPOT)	🍋🍋🍋
Three different symbols	Lose $50	🍒🍋🍇
