Bonanza Billion is a 2021 BGaming slot with a 6x5 grid where symbols pay anywhere on screen. Winning symbols vanish and new ones fall in, and the free spins round adds multiplier symbols worth up to 100x. BGaming lists the top prize at 15,000x your stake. It suits you if you like tumbling pay anywhere games and want the option to buy the bonus, and you can handle high volatility.

How does Bonanza Billion work?

You play on six reels and five rows with no paylines. A win is based on how many of the same symbol are on screen at the end of a spin, wherever they sit.

After each win, the winning symbols are removed, the rest drop down and new symbols fill the gaps. This refill repeats until no new win appears, and all wins from that chain are credited at the end.

What are the Bonanza Billion bonus features?

Four, five or six scatters award 10, 20 or 30 free spins, and three scatters during the round add 5 more. Multiplier symbols appear only in free spins. Each one takes a random value from 2x to 100x, and the total of all multipliers in a chain is applied to that chain's win once the refills end.

Chance x2 raises your bet slightly to improve the odds of landing scatters in the base game. Buy Bonus lets you pay to start free spins directly, with the price scaling with your stake. The two options cannot be active at once, and some countries do not allow them.

Is Bonanza Billion worth playing? RTP and volatility explained

BGaming lists the RTP at 95.97%, a little under the industry average. BGaming lets casinos choose between several RTP settings for many of its games, so the version you open may pay back less than the top figure. The game rules screen shows the exact value at your casino.

BGaming's own page gives an unusual low to high rating, while catalogues list high. The base game pays small amounts often, but the big wins depend on landing several multipliers in one free spins chain. Expect plenty of bonus rounds that pay less than their cost if you buy them.

The game shares its pay anywhere and bomb style multiplier idea with other popular fruit and candy slots, so if you have played those you will know what to expect. BGaming has since released Merge Up versions under the Bonanza Billion name, which are different games with their own figures.

Tips before you play Bonanza Billion

  • Check the RTP in the game rules before you play.
  • Do the maths on Buy Bonus before you use it, since the cost adds up quickly.
  • Use the demo to see how often multipliers land in free spins.
  • Keep your stake low enough to last through dry spells.
  • Set a loss limit and stop when you hit it.
