Billion Dollar Gran is a classic slot based on the number of reels (3) and lines (1), but if you look closely at the kind of features it offers, you will figure out that it’s a bit different from other games which sport the same layout. It’s not the only one of its kind, Microgaming having a couple of them in their offer. The theme seems to be based on a sweet old granny that is doing some knitting in the background, with a cat sleeping next to her. The reels host 1 line and it brings you win spins, which can then offer payouts of up to $20,000.

Betting & Jackpots

All games of this type, with lots of features and win spins instead of regular payouts, will have the same wager system, with 1 coin which goes from $0.10 to $10. That’s your maximum wager per spin as well.

The game has a top payout of 2,000 coins if you reach the bonus feature, and that would mean up to $20,000 cash for the player.


First of all, it is worth explaining how the game works, with win spins instead of regular payouts in the base game. You can form combinations which bring you between 1 and 25 win spins, which are basically free spins that can bring you payouts. The prizes offered during the win spins come from a different set of symbols.

The base game will have a nudge feature that will help you from time to time, allowing you to move into position symbols. A nudge will allow you to move one symbol up or down, by nudging the entire reel in the needed direction.

Finally, the slot has a Video Feature, a bonus game which you trigger with 3 Bowls on the reels. This feature can offer a payout of 2,000x, meaning $20,000 cash.


The game has an incredibly busy design, with a lot of things going on in the background. The granny is shown on one side, sitting in her house and knitting, while on a table nearby there are stacks of cash and gold coins. The symbols are a mix of jewelry, granny, coffee cups and classics (sevens and cherries).


It’s not the only game of its type that Microgaming offers, so you can pick the one that you prefer, based on the theme. They’re quite similar otherwise.
