Diamond Mine is one of IGT earliest versions of the video slot games with a bonus round that is associated with the game. Diamond Mine is a five line five reel with a maximum bet of 50 credits per spin. Some of the reel symbols represent the things in common with a diamond mine like, diamonds, diamond ring, ore cart, sparking bars, dynamite sticks and some fruit symbols. The top award is when five diamonds land on a payline with the maximum of credits bet per line. The Dynamite Bonus round is initiated when 3 or more sparking symbols, whether is a sparkling cherry or sparkling bar, land on a betting payline on the first 3 reels. The video screen changes to where the slot player sees five bundles of dynamite sticks on the screen. The slot player then picks one of the five sticks of dynamite by touching the screen. The next thing the slot player sees and hears is a flash of the exploding dynamite and the number of credits is revealed behind the exploding dynamite. These credits in the bonus round are then added to the total number of credits that was remaining before the bonus round. The bonus screen then reveals the value that was behind the other bundles of dynamite sticks. The more sparking symbols that initiate the bonus round, the higher the value is behind the bundles of dynamite sticks. Have fun and dig your way into riches.
