Booongo Gaming seems to have gained momentum with its multiple Hold & Win titles in all kinds of outfits (designs), feature mutations, and variations of 1 or more technical aspects.
We counted 24 games released by this Ukraine and Taiwan-based Studio in the last 2 years (2020 and 2021), where the megastar is Hold & Win mini-game.
It is loosely based on the 1955 movie The Gold Express, where a gazette reporter has been sent to cover the shipment of a huge quantity of gold bars while some professional thieves are preparing for the biggest payday of their lives. Well, the slot lives out the suspected criminals, but the rest of the passengers are handsomely outlined.
Besides building the slot with excellent graphics (cartoonish style) and audio style (very pleasant jazz melody throughout the whole game), Booongo threw in some femme Fatales in a seductive blond and brunet form to make the plot more engaging.
This Medium Volatility railroad action comes on a regular 5×4 playing field, crossed by 20 paylines. Released with a slender hit rate (only around 19%) and with an RTP of 95.64% – below the established industry average.
It carries the weight of 2000x the total bet Grand Express Jackpot (from the Hold & Win mini-game). In addition, there are 2 more marvels in this machine, which generate great excitement and can deliver significant payouts: the Piggy Boost feature and the Power Wilds.

Bonus Features of Gold Express Hold & Win slot
- Wilds – A Suitcase overloaded with gold coins is the Wild element in the slot. It can appear on all but reel 1 during both – main game and FS. It is a non-paying icon but has special powers in the Free Spins – it can come with Multiplier x2 or x3 attached to the suitcase, which will then double or triple the wins, in which it partakes.
- Moreover, if plural such Power Wilds are part of the same payline, they multiply their number. This way, you can get 3 raised to the power of 4, i.e. 34 = 81 max Multiplying factor in the FS. As usual, the Wild also replaces all missing icons except the Bonus icons (Gold Coins) and the Golden Train (Scatter) in the process of creating or bettering winning combinations.
- Scatters and Free Spins – The gold-plated Train is the Scatter – top valued symbol on the provision board with 50x the total bet for 5OAK and the only icon that doesn’t come Stacked. 3/4/5 Scatters, landing in 1 spin will activate the FS Bonus, consisting always of 8 rounds, with a chance of re-trigger. During the FS, the Power Wilds, the Boost Feature and the Hold & Win mini-game are all active.
- Bonus Symbols – The Gold Coins are the Bonus icons. They can turn up through the entire game, holding various cash amounts. 6+ Gold Coins will instigate the Hold & Win mini-game, with 3 Re-spins on the outset.
- Boost Feature – The Piggybank is a special symbol, which appears just on the 3rd reel during base and FS, but on every reel during the Hold & Win feature. It is the wondrous price collector. If it appears in front of the grid, the Piggy Boost has the ability to extract the cash amount of all Gold Coins currently on the reels.
By including the Boost feature, the developer gives a chance to receive any 1 or more of the small Jackpots even in the base game (i.e. without launching the Hold & Win mini-game).
Imagine you get several Coins (less than 6, so the mini-game will not start), and at the same time, you receive the Piggy Boost. If any of the landed coins is a Jackpot Coin – then here you go – the Piggy will collect for you all the amounts (including the Jackpot) right from the base game. This way, you can gain 220x the total bet with no sweat!
