Billion Dollar Gran belongs in a special category in Microgaming’s slot machine collection. There are regular 3 reel slot machines that they offer, and then there are some that seem to offer the same recipe, games with very busy designs, with win spins, nudges and elaborate bonus games, which always require the same wager and give away about the same prizes. Billion Dollar Gran is one of those titles, a 3 reel game with 1 win line in the base game, which has nudges and bonus games to offer, along with win spins. The theme tells the story of a granny that is a billionaire. The win spins are the ones giving you the prizes, and they can reach $20,000.
Betting and Prizes
You work with a single payline, placed on three reels. You also use only one coin for all your bets, and you are free to vary its value between $0.10 and $10. That coin value will be the wager for the round.
The rewards will come from the win spins, which offer their own symbols and which can pay up to 500 coins, the value of such a prize going up to $5,000.
Billion Dollar Gran Slot Features
The slot’s prizes will not be offered directly in the base game, which is an unusual way to play such a title. Instead, the game offers you win spins, between 1 and 25, and they are guaranteed to bring you a prize. You get nudges as well in the base game, which are used to help you form combinations when the symbols you need are nearby, but not directly on the line.
You trigger a bonus game through a Bowl, when it is present three times on the win line. The Video Feature that starts at that point will be capable of offering up to 2,000x in prizes, meaning $20,000.
As for the win spins, when you trigger them you will be taken to a different set of reels, still 3, but now offering 5 lines and completely different symbols. The prizes will vary between 1x and 500x here.
Theme & Design
There are two sides to this game. Initially, you are shown the granny’s room, where she knits with her cat sleeping nearby. This is where you get win spins from, by forming combinations with the Granny, Jewelry Box, Coffee, 7s or Cherries. During win spins, you go on the golf course, and the symbols include a cruise ship and a young man as well.
Billion Dollar Gran is not your typical classic slot machine, but I consider that a plus in its favor. It’s quite similar in the way it plays to other slots from Microgaming, which seem to mostly change the theme, and little else.
