Diamond Time Bonus Game

AC Coin & Slot

Diamond Time Bonus Game

This is a new game employing the scrolling bonus popularized by “Bankroll,” called the “Big Roller Bonus Event.” It is a five-reel stepper designed for the dollar player, with a 20-line format and a 20-coin max bet.

The base game is the five-reel version of IGT’s Double Diamond, which has been a workhorse for AC Coin’s bonus games. The top line jackpot is $5,000, but what makes this game unique is the scrolling bonus, which can yield a top award of $2,000 itself. The bonus occurs every 46 spins on average, which is twice as frequently as the bonus events on most slots, and 10 percent more frequent than the bonus on the original Bankroll game.

Three or more bonus symbols on any played payline trigger the bonus, on a scrolling display in the top box. The player is prompted to press a start button, which starts the vertical bonus award strip spinning. On the award display are 14 different award values, ranging from 20 credits to 200 credits and five multiplier values-2X, 3X, 4X, 5X and 10X. The multiplier value is selected first, then the pay value is selected. The combination of the two is the total bonus value awarded. All wins are multiplied by the initiating line bet.

This game takes a bonus event that has been proven to be wildly popular with players, and combines it with a dollar denomination in a multi-line setup that offers the best of both worlds for the operator-relatively low volatility and a high average bet. This will be a good addition to the high-end slot room in any casino.
