A slots win bonanza is surely something that any online slots fan would happily mine for. It is precisely that kind of bonanza that we are hunting in this six reel, 117,649 pay-lines slot from Big Time Gaming. That’s right. 117,649 pay-lines. It’s not a typo, but instead forms part of BTG’s appropriately-titled Megaways™ series of slots. Have you ever seen such a mouth-watering pay structure? Other than in your online slot dreams? In that way, Big Time Gaming is literally offering us the Bonanza mining platform that can make our dreams come true.


Fittingly enough, Bonanza Megaways Slot is set in the world of prospecting. Our main reel case is a six reel, five row mega mining structure carved into a hillock. Precious stones make up our high-paying symbols in the shape of Emeralds, Sapphires and Rubies, though it is Diamonds that reserve the right to the top-payout symbol. It’s worth noting that we only require two Diamonds to earn a payout, and rightly so. Most of us would settle for one. 9s through Aces make up our readily-occurring low-paying symbols, though, of course, it is the gleaming jewels that we are truly after.

Above the reels sits a four-berth mining cart, each containing a symbol which bumps up our Ways-to-Win yet further and helps us on our way to prospecting gold. Symbols can also appear double-size, offering extra wins per spin. But it’s not just single wins we are mining for. Big Time Gaming multiplies our chances of concurrent wins in Bonanza by augmenting winning combinations with exploding winning symbols in what the studio is calling Reactions. New symbols replace those exploded, which shuffles the pack and can potentially deliver multiple wins from a single spin.


On top of our Reactionary base game, BTG gives us the power of dynamite to explode these caverns in our search for riches. Wild carts of dynamite substitute for all symbols except Scatters to form winning combinations, allowing for new Reactions to take place.

But Bonanza’s bonus feature is the ultimate aim as we literally prospect for GOLD. four golden letters – G, O, L, D – make up our Scatters, and landing all four of them launches the game’s Free Spins feature. Our reel case and game board transforms into what we can expect beneath the surface of this prospecting adventure – an underground mining bonanza. Now, we have 12 free spins, with five additional spins granted for every extra Scatter we land. But we also have access to a win multiplier, which increases with every concurrent reaction. Mining dreamland.


When we land the Free Spins feature, we are looking at a potential payload of epic proportions. This is a mid-high online slot in terms of volatility, so landing that all-important bonus feature is our key to prospecting heaven. The good news is that there is plenty during the base game to keep our prospecting heads sieving through those reels in the hope of landing the payload we all dream of.
