Bonanza Megapays also features the brilliant Megaways game mechanic, which means that there are as many as 117,649 ways to create winning combinations.

The top prize (aside from the jackpots) is an amazing 17,926 times your total stake while the RTP is an impressive 96.4%.

Reactions allow you to create additional wins as the symbols cascade, and in the Free Spins Bonus, there’s an unlimited win multiplier feature.

How to Play

Before you begin playing Bonanza Megapays, you must pick a bet size that you’re comfortable with. The minimum amount that you can wager on each spin is 20p while the maximum is £30.

You can also choose to spin the reels manually or set the Auto-Play function up to take up to 100 automatic spins.

You can create winning combinations by landing 3 or more matching symbols on adjacent reels from left to right. However, the symbols that appear in the mine carts at the top of the screen can also contribute towards wins.

If you want to mute the music and sound effects, read the rules or view the paytable, simply click the blue button above the Spin button.

The symbols on the reels of this game are:

  • Diamond
  • Ruby
  • Sapphire
  • Emerald
  • A
  • K
  • Q
  • J
  • 10
  • 9


Due to the unlimited win multiplier feature in the Free Spins Bonus, it’s possible to win up to 17,926 times your total bet.

There are also four progressive jackpots up for grabs, the smallest of which seeds at £100 and the largest of which seeds at £300,000. The jackpots can be won through the randomly awarded Megaways feature which uses a Megapays Ladder.

Special Features

Wild symbols

Like in the original Bonanza slot, Bonanza Megapays features a wild symbol that’s represented by the red stick of dynamite. Wilds only appear in the mine carts that run along the top of the reel set and they can replace every other symbol apart from the scatter.


BTG’s Megaways system replaces traditional paylines to give you up to 117,649 ways to create wins.

The number of available Megaways depends on how many symbols appear on each reel following a spin. As each reel can contain between 2 and 7 symbols, you’re guaranteed a minimum of 324 Megaways.


Reactions is a feature that’s similar to tumbling, rolling or cascading reels. Each time that a win is formed, the winning symbols are removed and new ones from above fill the spaces that they leave behind. Reactions continue to occur until no more wins are possible which means that you can potentially enjoy multiple successive wins.

Free Spins Bonus

To trigger the Free Spins Bonus, the four scatter symbols (G, O, L and D) must all appear in any order on the same spin. You receive 12 spins when the four scatters appear, but you can win more if any “+5” symbols appear alongside them.

The Free Spins Bonus uses Reactions, and you also have a win multiplier that begins at 1x and increases by 1x with each new win. Collect three gold bars in the mining carts above the reels to gain an additional 5 free spins.

Megapays Feature

The Megapays Feature can be awarded on any given spin, and it selects one of the playing card symbols to act as the Megapays symbol. The reels then spin again and if the Megapays symbol appears, the remaining symbols are removed and a re-spin occurs.

The jackpots are awarded according to how many Megapays symbols appear. 4 to 7 symbols get you the Mini Jackpot (seed amount £100), 8 to 11 symbols get you the Midi Jackpot (seed amount £1,500), 12 to 14 symbols get you the Major Jackpot (seed amount £20,000) and 15 or more symbols get you the Mega Jackpot (seed amount £300,000).

Graphics and Sounds

Bonanza Megapays boasts a detailed background that includes the entrance to a goldmine that is cut into the hillside, a little wooden hut and a fully functioning water wheel. There are also some nice animations of the minecarts running along the track above the reels.

Toe-tapping banjo music and the sound of dynamite exploding help to keep the gameplay bounding along.

The number of Megaways is shown in an area just below the four jackpot values and the game controls are located at the bottom right.


Megapays is a brilliant addition to Big Time Gaming’s portfolio, as well as the Bonanza video slot.

It retains all the exciting special features that we’ve come to know and love while also giving you the chance to scoop one of four jackpot prizes.

You can get started playing Bonanza Megapays at Unibet, one of the most popular UK online bingo and casino brands recommended by the team at WhichBingo.
