Bonanza Slot Review

Bonanza slot is one of the most popular online slots of all time! Bonanza was the first game with the Megaways feature! It was invented by the developer of this slot Big Time Gaming.

Gamefield & Symbols

Bonanza is not an average 5 reel and three-row slot, instead it has six reels, five rows and 117649 pay lines. To put it simply Bonanza has a peculiar game field that stands out from the crowd. The game takes place in a mining field and a Bonanza, since it certainly is a rich source of a certain metal, gold!

However, the reels and rows make up the actual game field and are inside the mine. In the background are the gemstone and metal diggers cabine and other stuff that belongs to a typical mining field. Above the reels are wagons that transport symbols (gold, gemstones, letters, numbers), these wagons go inside some kind of a tunnel.

This slot has rolling reels or a reaction feature, which means that every time there is a win, new symbols fall down the reels to create new wins.
The game field is beautiful, so are the symbols! The lower valued symbols are letters, 9, 10, J, Q, K and A. The higher valued symbols are the gem stones ( Sapphires, Emeralds, Diamonds and Rubies).

In the game are also symbols G, O, L and D. The goal is to get those gold symbols and receive Free Spins! It’s possible to receive up to 7 symbols per reel, and the slot pays for most 3 or more adjacent symbols that you receive from left to right.

A reel can show between 2 and 5 symbols, and there’s a set of small reels along the top of the game field. “Each reel shows a various number of symbols, this means that the total number of winning ways is different with each spin. This is an example of the Megaways mechanic.

Verdict & Conclusion

Bonanza doesn’t have loads of features, there is actually only one major feature and that is the Freespins! Despite that, the slot is entertaining. The slot is one of the best slots from Big Time Gaming and a pioneer when it comes to the number of ways to win and it was also the first slot with megaways function.

The only thing we miss is a big progressive jackpot in the game, otherwise this simple slot is surprisingly well functioning, smooth and well-synced. This mining game is a source of both gold and joy!
