Boomerang Jack’s Lost Mines Review

This release keeps players busy and offers gamblers another exciting experience. This title complements the studio’s portfolio. It’s an interesting game, with a theme that is a mix of different concepts, and there are entertaining and rewarding features included.

With Boomerang Jack’s Lost Mines, the team decided not to dwell on a usual idea, so the slot combines adventurous, mining, and Australian themes, and the result is nice. Here, you are to join the brave explorer Boomerang Jack on his journey to the Kalgoorlie Mine in Australia, which hides secrets. The three lost mines of the slot are what Jack hunts for, and each conceals gems that lead to bonus features and treasures up to 4,836x the bet.

As for stats, the Boomerang Jack’s Lost Mines slot is powered by a medium-high volatile math model. The hit rate is decent at 28.4%, meaning that wins should occur fairly often. The RTP is less impressive, clocking in at 95.3%, which is lower than average. Players drop in by setting bets from just €0.1 per spin, and the highest stake option is €25.

Ten pay symbols appear on the 5-reel, 3-row setup producing 25 ways to play. The lower section comprises classic A-10 royals, and the premium lot includes in ascending order koalas, kangaroos, crocodiles, explorers, and carts filled with gold ore. Three or more matching symbols landing adjacently on the reels starting from the leftmost create a winning combo, except for the cart, which needs only two. Five-of-a-kind low symbol wins are worth from 2x to 6x the stake, and higher symbols pay from 8x to 20x the stake. Finally, there are also Wild symbols included, which can appear on reels 2-5 to substitute for any other regular symbols in winning combinations, plus they can land stacked, covering the entire reel.

Boomerang Jack’s Lost Mines Slot Features

Most wins in the Boomerang Jack’s Lost Mines slot come from the different Free Spins features, each with its own extra modifiers. On any spin during the base game, green, red, or blue gems can appear on the reels to randomly launch the respective bonus game.

If at least 1 green gem symbol appears, 5 Gem Coins Free Spins can be triggered at random. New coin symbols come into play, and when one appears anywhere in view, it awards an instant cash prize equal to 2x the value of the current bet. If a gem appears during the free games, it increases the coin value and awards +1 additional spin.

If at least 1 red gem symbol appears, 8 Diamond Wins Free Spins can be triggered at random. During the bonus, new chest symbols appear, which can reveal either a cash prize, additional free spins, or one of the diamond symbols. The diamonds are collected and added to the respective meter. When enough symbols are collected, players are awarded the corresponding fixed jackpot prize:

• Four purple diamonds - award a Mini Jackpot of 10x the bet.
• Four green diamonds - award a Minor Jackpot of 30x the bet.
• Five blue diamonds - award a Major Jackpot of 150x the bet.
• Five red diamonds - award a Grand Jackpot of 700x the bet.

If at least 1 blue gem symbol appears, 5 Reel Expand Free Spins can be triggered at random. The feature operates in a similar way to the base game, but plays on expanded 5x5 reels with 50 win lines.

Moreover, if multiple gem symbols appear simultaneously on the reels, a combined feature of free games can be activated. The combined feature of two gems starts with 8 free spins and applies all the same rules associated with the gems involved. The combined feature of three gems starts with 10 free spins and includes all three gem modifiers.

Review Summary

All said and done, there’s surely a lot for players to get stuck into. With seven different free spins modes and a delightful theme, Boomerang Jack’s Lost Mines is bound to appeal to many. Yet, there’s still room for improvement when it comes to the payback and max win capability.
