Big Time Gaming presents the 6-reel, 5-row and 117,649 megaways-to-win slot Bonanza where you have the opportunity to mine for precious stones and dig up prizes of up to 50 coins per payline!
Dig for gems
The setting for this slot is the side of a rocky hill where the sound of stone cutting equipment permeates from caves within as they cut and blast their way through rocks in search of precious stones. These stones form the basis for the four highest paying symbols which are then followed by five poker symbols at the lower end. A water wheel spins adjacent to the reels and carts with symbols appear with different symbols above the 2nd, 3rd, 4th and 5th reels. The graphics quality is excellent as is the accompanying country-style music that makes a fast game feel even faster.
Reaction feature, wild and scatter symbols
Thre rail carts add symbols above the 2nd, 3rd, 4th and 5th reels. After a winning payline, the symbols involved explode only to be replaced by symbols above and from the right in the carts. Referred to as a reaction, this free cascading effect continues in a loop until no further combinations are created where the feature then ends. This slot also includes a wild symbol which replaces all other symbols except the scatter and only appear in the carts. The gold scatter can appear on any reels with four gold scatters unlocking 12 free spins with extra scatters beyond the first four adding an extra 5 free spins. During the free spins feature, there is an uncapped multiplier that increases by 1x after each reaction so long as the reaction continues. You can also unlock additional free spins by the appearance of free spin scatter icons. Three free spin scatters will award 5 extra free spins with 4 scatters awarding an extra 10 free spins.
Our 10 cents!
Bonanza has a theoretical return to player (RTP) of 96% and stakes that can range from €0.20 to €10. Although the slot has 117,649 ways-to-win, the slot variance is at least a medium since we found wins of any decent size not easily forthcoming. We, unfortunately, did find the free spins feature difficult to trigger while the reaction feature as you might expect was much easier though really failed to overwhelm us. The payline wins are not the largest we’ve seen either so to make this slot work you need to count on multiple payline wins but honestly, there are better-paying ones out there so you really have to enjoy the theme to play this one. If you do enjoy the theme then the slot is available to try for free prior to playing for money.
