AC Coin returns to its roots somewhat with this game, a traditional three-reeler with the familiar "Slotto" lottery-style bonus sphere on top.
The primary game is IGT's Double Gold, a strong game in its own right, featuring an ample pay table with multiple "7" combinations, and duplicate symbols marked with the word "Double." When one of these lands on the payline in a winning combination, the jackpot is doubled. Two of them multiply the jackpot by four, and three of them multiply the pay-table combination by eight.
This applies to all but the top jackpot of three double 7s, which returns 10,000 coins with the maximum three-coin wager.
Slotto Double Gold is designed as a high-denomination game. The player can choose a quarter, 50-cent, dollar or $5 denomination, which really jacks up those multiplied wins. Then, of course, there is the classic Slotto game. If the Slotto symbol lands on the third reel at max-coin, the balls begin swirling inside the bit Slotto sphere until one drops to award the player a bonus amount. The award scale is designed to benefit the high wager: The lowest-paying bonus is 20 credits, and top Slotto ball pays 1,000 credits. The average bonus pay is nearly 60 credits. The event happens every 60 spins, on average, a frequency the company says is typical, and adds to the appeal of all its games.
The game promises to be one of the strongest in a series that has seen its share of sustained success.
