Bullion Bank slot
Bullion Bank is a Northern Lights Gaming slot set inside a bank vault, played on 5 reels and 4 rows. Its base game revolves around the Money Pile: coins gather in a pile that a Collect symbol on reel 5 cashes in, with piggy banks and multipliers adding to it along the way. Three or more scatters open the Double Dollars Bonus, where Keys unlock locked rows and filling every spot with Bullion awards the Grand Jackpot.

Rules, features and payout figures are set by the studio and can differ between operators and game versions, so check the game’s information panel before you play.

| Money Pile | Coins add their cash values to the pile; Mystery Coins add a coin whose value stays hidden. The Collect symbol, which lands on reel 5, pays every coin and Mystery Coin in view (the paytable in our lobby says the Collect symbol lands on reel 5 in the base game, collects and awards all visible coin cash values, and empties the Money Pile and resets the feature) |

| Multiply Booster | Multiplies every coin value by 2x, 3x, 5x, 10x or 100x; Mystery Coins are excluded |

| Bankers Vault | A cash prize for each new Bullion symbol, growing in value after every award |

How Bullion Bank plays
Every spin lands on a grid of five reels and four rows. Beside the regular paying symbols sit feature symbols, and most of them feed one of two features. Coins, Mystery Coins, Piggy Bank symbols and Multiply symbols work on the Money Pile, a running stash of coin values that only turns into a win when a Collect symbol arrives on the fifth reel.

To the right of the reels, a tall column carries a Double Dollars Extra Life badge at its foot. The bar above the game shows your net position, £0.00 here, and time played, which UK rules require for online slots. Game and artwork © Northern Lights Gaming.
Scatters do two jobs. Three or more in one spin start the Double Dollars Bonus, the respin round where the jackpots live, and scatter tokens also fill the Bankers Bar, which unlocks an extra respin for that bonus.
The Money Pile and the Collect symbol
Coins that land add their cash values to the Money Pile, and the pile keeps building until a Collect symbol reaches reel 5. At that moment every coin and Mystery Coin in view is paid. Three helpers change it first. A Piggy Bank symbol adds a random amount of coins each time it appears. A Multiply symbol boosts every coin value by one of five multipliers, listed in the table, though Mystery Coins are left out of the boost. A Mystery Coin keeps its value secret until the Collect lands.
The Double Dollars Bonus
Three, four or five scatters start the Double Dollars Bonus, and the number decides how much of the grid is open at the start: with three, rows 1 and 2 begin locked; with four, one of those rows is already open; with five, the whole grid is in play. The round gives three respins, and only Bullion, Keys and blank positions spin. Every new Bullion symbol picks up the Bankers Vault cash prize, which then grows for the next one. Two Keys open a locked row. Once no rows are locked, a single Key unlocks one of four jackpots, and covering every position with Bullion awards the Grand Jackpot.
Bullion Bank compared with Coin Strike: Hold and Win
Playson’s Coin Strike: Hold and Win is also built around a symbol that gathers prize values, on a much smaller 3x3 grid. There, the Strike Bonus symbol collects the values of the Bonus and Jackpot symbols that land with it. Bullion Bank spreads the collecting idea over a larger 5x4 grid and stretches it across spins: its coins wait in the Money Pile until a Collect symbol on reel 5 pays them out. Its jackpots also sit apart from the collecting, inside a respin bonus where they are unlocked with Keys.
| Game | Grid | Collecting symbol |
|---|---|---|
| Coin Strike: Hold and Win | 3x3 | Strike Bonus symbol, collecting the Bonus and Jackpot symbol values with it |
| Bullion Bank | 5x4 | Collect symbol on reel 5, cashing in the Money Pile |
All values (Bet Levels, Maximum Wins etc.) mentioned in relation to this slot game are subject to change at any time.

Frequently asked questions
How do you get four respins in the Double Dollars Bonus?
By filling the Bankers Bar. Scatter tokens collect in the bar, and once 20 of them have filled it, the Double Dollars Extra Life is unlocked. Every Double Dollars Bonus after that starts with four respins rather than three. The studio describes the Extra Life as permanently available once unlocked, so it does not reset when a bonus round ends.
Does a Multiply symbol boost Mystery Coins in Bullion Bank?
No. A Multiply symbol raises the value of the ordinary coins in the Money Pile, but Mystery Coins are excluded from its boost. A Mystery Coin only shows what it is worth when the Collect symbol lands on reel 5 and gathers every coin in view, so its prize is revealed at the same moment it is paid.
Where are the jackpots won in Bullion Bank?
Inside the Double Dollars Bonus. Key symbols appear in that round, and the first job of the Keys is to open locked rows, two Keys per row. Only after every row is unlocked does a single Key unlock and trigger one of the four jackpots. The Grand Jackpot works separately: it needs every position on the grid filled with Bullion.
