Pack your explorer gear to join the female ruby hunter and her four men in their quest to find the precious gems hidden in a mine deep in the jungle on the slot from Kalamba Games. Free Spins, Jackpot Symbol Respins and three personal progressive jackpots can lead to wins of up to 1,000x time your bet in the base game and virtually unlimited from the jackpot pays.
Ruby Hunter is a video slot with 6 reels, 3-4-5-5-4-3 rows and 3,600 ways to win. Pays are awarded for adjacent symbols from left to right only. You can go on your ruby hunt on mobile or desktop from 0.60 to 120 credits. The RTP of this medium variance game is ranging from 96.65% to 97.54%, depending on whether the Hyper Bonus bet is used.
The deep abyss of the ruby mine can be seen in the background of the elaborate game window with frameless reels. Spider webs, skulls and snakes ornament the stone frame while a rather heroic soundtrack goes into dramatic crescendos on big wins and teaser spins.
The pay symbols start at the low end with the forever used card royals from 9 through to A. Pays for a single six of a kind are rather modest with 1.66x to 2x your bet. They are followed in ascending order by four male hunters and explorers and ultimately, the leader of the expedition, a dashing female ruby hunter. Pays increase to 3.33x to 5x your bet. All symbols can appear in stacks of up to three symbols high.
The wild symbol is a tribal mask, appearing on the centre reels only and substituting for all symbols bar scatters and jackpot symbols. Scatters are an entrance to an ancient temple with the word bonus across, while an intricate arrangement with a red ruby is the jackpot symbol.
A bonus buy feature has become routine on many slots these days, and Kalamba Games also included it on Ruby Hunter. There are four options available, each with an increasing amount of free spins and the overall RTP rising from the default 96.65% to 97.54% when Level 4 is purchased.
To trigger the feature organically, you need to hit three to six scatters in one spin, which will activate 8 to 20 free spins, which can be retriggered. Coins wins from 2x to 50x bet are also awarded. Three or more bonus symbols during the round will add the same amounts of free spins. The main attraction in the free spins is the jackpot respin feature where you are playing to win one of the three progressive jackpots.
Three progressive jackpots – Silver, Gold, Platinum – are displayed in the top right corner of the game window. The seed value is set at 20x for the Silver, 100x for the Gold and 1,000x your total bet for the Platinum jackpot. These are personalized jackpots specific for each player and each casino account with the balances stored when the game is closed. Roughly 2.5% of each bet contribute to the jackpots – 1.75% to Silver, 0.7% to Gold and 1.0% to Platinum.
The jackpots can only be won in the free spins feature. Hitting minimum three jackpot symbols will trigger a respin with the triggering symbols locked for a chance to land more. Any further appearing on the respin will see them locked in as well, plus the respin is retriggered. This continues until no new jackpot symbols land of a respin.
Three to fourteen jackpot symbols will pay 2x to 15x your total bet. To win the jackpots you need to hit 15 – 19 for the Silver, 20 – 23 for the Gold and 24 symbols for the Platinum. After the payout, the jackpots are reset to their respective seed value. Any line pays from the respin sequence will be added to the jackpot wins.
It looks like Kalamba Games really embraced slots with personal jackpots and bonus buy features. While they provide extra suspense and choices for players, it also impacts the gameplay. The highest RTP is only active with the top feature buy option, while the rest is then played at a lower setting. It’s not a bad thing per se but we do prefer to have one overall RTP as it is then evenly distributed for the base game and features. Nevertheless, Ruby Hunter is well designed and has good win potential, so well worth to go on a reel hunt for those precious gems.
