Play Demo Bonanza Slot Machine for Free

Demo mode of the Bonanza slot game by the Big Time Gaming provider allows you to play for free with virtual currency.

When playing in the demo mode, you can get acquainted with the slot gameplay and just have fun.

Free Online Bonanza Slot Review

This Megaways slot has 6 reels, up to 117,649 paylines per spin, Wild and Scatter symbols, and a bonus game with free spins and infinitely increasing multiplier. The slot machine RTP is 96%. The maximum win is x26,000.

How Bonanza Slot Works

The game’s goal is to obtain winning combinations. You need to specify the bet size and start spinning the reels. If you manage to collect a prize combination, its symbols explode thanks to the Reaction mechanism, freeing up space on the playing field for new ones and giving you another chance to win. When the reels spin, each of them displays 2-7 symbols. Above them are 4 mining carts which bring additional symbols.

Graphics and Plot

The slot has bright and beautiful graphics, and is dedicated to the theme of gold and gems in the mine from the Wild West time. The playing field is made up of rough stones and a mine entrance and is set against the backdrop of a picturesque forest clearing with a water wheel and an authentic wooden miner’s hut. The atmosphere of a reckless treasure hunt is successfully emphasized by the sounds of pickaxes hitting rocks accompanied by cheerful American folk music.

Game Symbols

The role of simple symbols is played by card denominations — 9, 10, Jack, Queen, King, Ace, and precious stones — pink diamond, red ruby, blue sapphire, and green emerald. The most profitable are combinations of stones, among which the most valuable is a cut diamond which can give the maximum prize equal to 50 times the player’s bet.

Scatter symbols are represented by four golden letters — G, O, L, D, which, having appeared together on the playing field, start the free spin round. Free Spins Scatters appear only during the bonus game with free spins in carts above the playing field with spinning reels in the form of carts with gold bars.

The Wild symbol is represented by a lit dynamite and can substitute for any other symbol except for the Scatter.

Winning Combinations

To know the gameplay better, players can play free games in the Bonanza slot. The basis of the game in any slot machine are winning combinations. Their role is played by three or more identical symbols that appear on adjacent lines. This allows you to significantly increase the potential gain. Prize combinations start from the leftmost reel and are formed from left to right on sequentially located adjacent reels.

While the player can only get x50 of their bet on one line, the multiplier and cascading reels can provide an even bigger win of up to x26,000 the original bet.



RTP and Volatility

RTP (Return To Player) is a theoretical statistical percentage of the total amount of bets placed in the slot machine, which is paid out to players as winnings. This value is calculated by dividing the total payout amount by the sum of all bets placed within the multiple test reel spin. RTP may vary for different versions of the game. The Bonanza slot from Big Time Gaming has the 96% Overall RTP and 96.11% Bonus Buy RTP.

This game has a high volatility, that is, during the gameplay, players do not receive prizes often, but when they do the winnings themselves are usually larger. Low variance games are opposite in terms of their payout parameters — they provide smaller winnings, but they do it more often.

Jackpot & Maximum Win

The biggest prize that can be won on Bonanza Megaways is the x26,000 player’s bet. Although such a win can theoretically be obtained during the main game, its probability increases significantly during the free spins round due to the unlimited possibilities for making the multiplier bigger.

Alas, online casino slot Bonanza does not have a progressive jackpot.

However, there is its close analogue that compensates for this shortcoming the Bonanza Megapays casino game. Its only difference is the addition of a progressive jackpot, the prize round of which is triggered randomly and played using a randomly selected Megapays symbol. The jackpot size determines the number of such symbols on the playing field.

In Bonanza Megapays, you can win a jackpot with the following results:

  • Mini Jackpot: €100
  • Midi Jackpot: €1,500
  • Major Jackpot: €20,000
  • Mega Jackpot: €300,000

Minimum and Maximum Bets

When a player decides to play free Bonanza slot for fun, virtual chips are available to them. However, in all other respects, the demo mode is no different from the full version, including the bets. Their range varies from $0.2 to $20.

Bonanza Bonus Features

Bonanza Megaways offers 4 bonus features:

  • Bonus round with 12 free spins, which is activated by 4 Scatters.
  • The Buy bonus function. With its help, you can start the free spins round without waiting for all 4 Scatters to appear on the playing field.
  • A multiplier that is activated as part of the bonus game which increases with each win. Theoretically, it can grow indefinitely.
  • The Reaction feature, thanks to which symbols from winning combinations explode and new ones appear in their place, giving a chance for another win. This continues until the moment when the prize combinations end on the playing field. Due to this, the number of possible prizes per spin increases significantly.

Multiplier Symbols

There are no such symbols in the regular game, but there is a multiplier in the bonus game it grows by one with each new win within the free spins round. Since its size is not limited by any value, it allows you to win several large cash prizes at once.

No Deposit Free Spins & Bonus Rounds

To activate a round of free spins in the Bonanza slot, at least four Scatters should appear on its playing field at the same time — G, O, L, D. They provide 12 free spins. Each additional Scatter symbol adds five free spins.

Undoubtedly, the key feature of the free spin round is the unlimited multiplier, which is not available during regular play. It grows every time by one after the next operation of the Reaction function.

Free Spins Scatter can give 5 or 10 additional free spins if 3 and 4 copies fall out respectively. It also appears only during the bonus game with free spins in carts above the playing field with spinning drums in the form of carts with gold bars.

To sum up, Bonanza offers an impressive bonus game with cascading wins, an unlimited multiplier, and the possibility of getting additional free spins.

If you want to activate a free spins round, you can just buy a bonus and start calculating profits.

How to Play

Before you play online Bonanza slot machine for real money, you need to be well acquainted with its rules.

Slot Launch

Quick guide to start the game:

  1. Press the menu button.
  2. In the drop-down list, you can familiarize yourself with the payout table, study the game rules and turn off the sound if you wish.
  3. Set a bet (using two small arrow buttons).
  4. To use the Autoplay function, press the Auto button (with curved arrows). In the drop-down list, select the number of spins, the win and loss limits.
  5. Set a bankroll and press the Play button (with a big arrow) to start the game.

Betting Options

The player can bet $0.20-$20 per spin. This is a comfortable range for players on a relatively small bankroll. However, high rollers will also be happy as they are able to receive bigger winnings.


To start autoplay, you need to click on the Auto button. In the Settings panel that opens, you can specify the number of spins (no more than 100) and the events that will complete them — the limit of losses and a one-time win. Autoplay will also stop if the free spins bonus round starts. When a player’s loss limit is set, they can start autoplay. Pressing the Auto button again will stop it. The loss limit is necessary so that the bankroll does not deplete too quickly. This is an effective way to avoid overspending while playing.

Demo Mode to Play for Free & for Fun

Any player has the opportunity to spin the reels for free and get to know the gameplay features and bonus features. To do this, you can play demo slot Bonanza from Big Time Gaming. As part of the game in demo mode, bets in the slot are made with virtual chips. In all other respects, including the bonus game and the frequency of prizes, the simulator has no difference with the full mode.

The general recommendation for new players is to play at least 150-200 free spins on the slot machine before starting to place real money bets. This allows you to understand how profitable it is to spin the reels of the slot with your bankroll.

Gambling on Mobile & Tablet

Bonanza slot launches and works great on any modern mobile device. This allows you to play it literally everywhere. The game works on any Android, iOS, Windows, and Blackberry devices.

Tips for Players

Although the slot demo version offers a wide range of bets, gamblers with a large bankroll have an advantage when playing for real money which is due to the high volatility of the Bonanza slot where you can receive larger winnings but they do appear more rarely. At the same time, the total profit within a session is usually higher than in slots with medium and low volatility.

Therefore, players with a small bankroll risk falling into a no-win streak and depleting their money completely. Because of this slot feature, it is important for players with a small bankroll to think carefully about their bets. In this game, it is most reasonable to strive to increase the number of bets, spending less on each of them, which will eventually allow players to wait for the next cash prize.
