Gameplay and Features
The main attractions of Boomerang Jack’s Lost Mines are its creative free spins bonus rounds. These engaging mini-games are accompanied by multipliers, expanding reels and four possible jackpots.
Gem Coins Free Spins
Land at least one green gem to unlock the Gem Coins feature and collect five free spins. During this round, special coin symbols with cash prizes of 2x your bet come into play. Whenever a green gem appears during Gem Coins, it grants you an extra spin and increases the value of your coin symbols.
Diamond Wins Free Spins
Collecting at least one red gem may trigger the Diamond Wins feature to reward you with eight free spins. Chest symbols are activated which can reveal cash prizes, extra spins or a diamond.
There are four diamond symbols, each one attached to a Boomerang Jack’s Lost Mines jackpot level. Every diamond symbol you collect fills one cell of its respective power-up meter displayed beneath the jackpots.
Accumulate diamond symbols to fill their meter and collect the corresponding jackpot prize.
- Mini: This jackpot awards a 10x prize and is triggered when you collect four purple diamonds.
- Minor: Four green diamonds will activate this jackpot, which offers a 30x prize.
- Major: Landing five blue diamonds will fill up the Major jackpot metre for a prize of 150x your bet.
- Grand: The grand jackpot is worth 700x your stake and is won by collecting five red diamonds.
Reels Expand Free Spins
The Reels Expand round can be triggered randomly whenever you land at least one blue gem anywhere on the reels. Your reward will be five free spins on an expanded 5×5 grid with 50 paylines.
Combined Free Spins – Two Gems
Landing two different gem symbols may trigger a bonus game that combines the individual free spins feature related to each gem. This combined feature will award eight free spins and apply the modifiers of each gem’s bonus.
For instance, if you land a green and red gem, you may trigger the combined feature and collect eight free spins. During this round, the coin and chest symbols of the Gem Coins and Diamond Wins free spins will come into play.
Combined Free Spins – Three Gems
A bonus game combining all three free spin features can be triggered randomly if you land green, blue and red gems simultaneously. Your reward will be 10 free spins, during which the Gem Coins, Diamond Wins and Reels Expand modifiers will apply.
Regular Symbols
Low-value symbols in the Boomerang Jack’s Lost Mines paytable are standard playing card royals Ace to 10.
High-paying symbols include popular members of Australia’s wildlife, namely koalas, kangaroos and crocodiles. The main character Boomerang Jack also appears while a green mining cart filled with ore acts as the highest-paying symbol.
Scatter Symbols
Boomerang Jack’s Lost Mines does not have a Scatter symbol. Instead, it features three special gem symbols that can randomly trigger a free spins bonus whenever they land.
Wild Symbols
The Boomerang Jack’s Lost Mines Wild symbol is represented by the letters “WILD” emblazoned across a setting sun. They can appear stacked on the reels and substitute for every regular pay symbol. However, these Wilds can only land on reels two, three, four and five.
Boomerang Jack’s Lost Mines Free Spins
Somewhat uniquely, this slot is built entirely around five different free spins games. All of the game’s features relate to these randomly triggering bonus games. We explained how these features work in detail earlier in our Boomerang Jack’s Lost Mines review.
How to Win at Boomerang Jack’s Lost Mines
Winning combinations are formed by matching similar symbols from left to right on adjacent reels. When playing, aim for the green cart symbols. They can give you base game wins up to 20x your bet. Gem symbols are equally essential since they’re the only way out of the base game. They appear regularly but won’t always trigger bonus rounds.
We recommend practising for free to help you understand the basics of the game before risking real money. You can play the Boomerang Jack’s Lost Mines demo at any of the regulated casinos on this page.
