Boomerang Jack’s Lost Mines Theme
Boomerang Jack’s Lost Mines is a slot that blends several themes into one plot. It is among the games themed around the Australian flora and fauna. Here, players will come across recognizable animals from the smallest continent on the Earth such as koalas, kangaroos, and crocodiles. Card symbols from 10s to Aces deliver lower-value payouts.
With the mining theme at the heart of this slot, the highest-value symbols are Boomerang Jack and a mining cart. The audacious explorer is set to uncover some life-changing riches during his trip to the Kalgoorlie Mine in Australia. The so-called Golden Mile in the Kalgoorlie Goldfield is among the most bountiful gold deposits in the world, so reel spinners are guaranteed an exciting adventure, with the added potential to sweep generous fortunes.
The game is full of fun surprises and enthralling sound effects that will arrest players’ attention as they help Jack discover the precious gems.

Boomerang Jack’s Lost Mines Symbols and Payouts
The winning combinations in Boomerang Jack’s Lost Mines pay from the leftmost. The paytable comprises 10 regular symbols. With a treasure-hunt theme at the centre of the action, it is no surprise that a mine cart is the highest-paying symbol. It is in fact the only symbol from the paytable, which returns payouts for 2 matching symbols. A five-of-a-kind combo of mine carts generates payouts of 20x the stake. Jack himself comes next in line, returning rewards from 0.8x to 10x the bet for matching from 3 to 5 identical symbols on a win line.
The next three symbols of the slot are animal species that we associate with Australia. The first one is the symbol of a crocodile, which pays at a rate from 0.8x to 10x the bet value when players line 3 to 5 symbols on a win line. Kangaroos and koalas return identical payouts, which fall within the range of 0.8x and 8x the stake.
A-10 royals deliver the lower value payouts. Landing 3, 4, or 5 Aces on a win line triggers returns of 0.4x, 0.8x, and 6x the wager. Kings and Queens generate equal payouts from 0.4x to 4x the bet when players form combinations of 3 to 5 identical icons. Finally, Jacks and 10s return profits from 0.4x to 2x the stakes for 3-, 4-, and 5-of-a-kind combos.

Wild Symbols
The slot’s Wild symbol can stand in the place of all other symbols, except for the gem, chest, and coin symbols. It can land on reels 2, 3, 4, and 5.
There are three gem symbols – green, red, and blue. Their role is to trigger the three free spins features.
Free Spins
The slot is equipped with three different free-spin features: Gem Coins, Diamond Wins, and Reel Expand.
Landing at least one green gem symbol anywhere on the reels during the main game can activate the Gem Coins feature, which awards players a total of 5 free spins. While the Gem Coins feature is active, each gold coin symbol awards a win, and green gem symbols award an extra free spin.
The next precious gem, the red one, can trigger the Diamond Wins feature, regardless of its position on the reels. Players receive 8 Free Spins. While this feature is active, each chest symbol that lands on the reels awards extra spins, a direct win, or a diamond to get the Mini, Minor, Major, or Grand wins. When players receive diamonds, they are sent directly to their corresponding panel and once all positions are filled, the jackpots are won and reset.
The Reel Expand feature can be activated when players land at least one blue gem symbol anywhere on the reels. This is the feature, which expands the grid configuration to 5 reels and 5 rows and players enjoy 5 rounds of Free Spins. The number of win lines during this feature is automatically reset to 50.
Combined Features of Two Different Gems
As already mentioned, there is the opportunity to combine different features. If players land 2 different gem symbols during the base game on any position on the reels, they may be awarded 8 free spins. All rules applicable to the relevant features will be in force.
Combined Features of Three Different Gems
Landing at least one green, one red, and one blue gem symbol in any position on the reels may trigger randomly the combined feature of 3 gems. Players receive 10 free spins, with all rules associated with the individual features in operation.
