However, Bonanza is still the number one Megaways game thanks to its fun theme, great graphics, cool gameplay, and most of all excellent winning possibilities. New Zealand players can play Bonanza at Guts casino or try out BTG’s other exciting games.

The most valuable gem is the round purple one and it pays 50x your bet if you manage to collect all six. Since the Bonanza slot takes place in a mine where dynamites are in heavy use, winning combination of symbols explode and disappear from your screen.

There is a top row above the reels where 4 mining carts pull in on every spin. Each cart adds a symbol to the middle four reels. Winning symbols are replaced by symbols coming from above and from the right in the carts. The Wild symbol of the game is 3 dynamites that will heat things up and help you form winning combinations by substituting for other symbols
