I don’t remember seeing the name “Old Skool Studios” before, but many elements of the new 6 Rubies of Tribute online slot feel strangely familiar. Perhaps I'm just not remembering the name of the developer. Still, as they are working together with Microgaming to release this game, it’s fair to assume that this will be a reasonably high-quality production. Opening the game for the first time, it seems like quite a simple title, but the graphics are well drawn, and it looks nice on a big screen. The maximum bet of 1,300x your stake feels a little low, whilst the 25 fixed pay lines and 96.20% RTP are both right around average.
The headline feature is titled “link and win”, a name that I have definitely seen before on other online slots, but after a quick google search, it seems that multiple developers have used this same name for their bonus rounds in the past. Three jackpot prizes are also included, labelled MINI, MINOR, and MAJOR, with payouts of 30x, 100x, and 1,000x the current stake, respectively. A free spins bonus round is also included, making for a well-rounded feature set.

The title of this slot is somewhat ambiguous, and things do not become any clearer after looking at the paytable either! The symbols resemble totems, whilst the background appears to have several totem poles – a link, perhaps?! We’ve seen this kind of theme before in games such as the Aloha! Franchise by NetEnt and the look and feel of 6 Rubies of Tribute is quite similar overall, if perhaps slightly more serious.
We’ve already mentioned the jackpot prizes of 30x, 100x, and 1,000x your stake, but how about the regular paytable? Three scatters will pay you 1x your bet – the same amount the spin costs you – so it barely seems worthy of an inclusion, and you have to wonder why Old Skool Studios didn’t just allocate this small piece of RTP elsewhere. As for the regular paying symbols, the red cat-looking totem will pay you 20x your stake for a full pay line of five-of-a-kind, followed by the yellow parrot at 15x, the blue monkey at 12x, and the green frog at 7.5x. Four lower-paying royal symbols are based on playing card symbols making up the bottom half of the paytable, with payouts ranging between 2x and 3x the current stake.
Clicking on the plus-minus symbol above the spin button will open a new page with lots of wager selection options. You can choose the number of coins per line and the coin size or opt to change the overall bet size. This works out to a minimum cost per round of €0.10 whilst the maximum is €100.00 – a massive spread that is surely enough to satisfy every player.
There are few surprises as far as the base game is concerned in 6 Rubies of Tribute; we have a 5x3 playfield with 25 fixed paylines, and all winning combinations require at least three matching symbols on a line starting from the left-hand side of the screen. It would have been nice to see a modifier or two included here, but Old Skool Studios have concentrated their efforts (and RTP!) on the two major bonus rounds, which seems like a reasonable trade.
This modifier only triggers after a non-paying base game spin. The wild power cells will send you back in time, re-spinning all the symbols around them and adding additional wilds to the screen until you hit a win. I managed to dodge a win six times whilst I was testing this game, eventually hitting a base game win of 81x my stake – not bad at all!
This modifier works in the opposite way to the wild rewind; it only triggers after a winning base game spin and sends you forward in time! All your winning symbols will be upgraded, and the surrounding symbols will re-spin to give you a second chance at boosting the value of your winning combination.
There are two major bonus rounds in 6 Rubies of Tribute; firstly, the link and win feature requires at least six triggering Ruby symbols to activate and can potentially pay up to 1,300x your current bet. Secondly, a free spins bonus round can be won by hitting a separate set of three scatters, which appear only on reels one, three, and five.
Land six or more ruby symbols during the base game to trigger the link and win feature with a maximum payout of 1,300x your current bet per spin. You begin this mode with three spins, and any rubies that land on the screen will reset your remaining counter back to three.
If you manage to go three spins without any rubies landing, the feature will end, and any winnings you have collected will be paid. During the link and win feature, the regular reels are replaced by a new set that only includes ruby multiplier prizes and blank spaces. If you manage to fill the screen with ruby symbols, you will automatically win the largest jackpot prize!
Three unique mask symbols appear on reels one, three, and five only, and catching all three of these will trigger a separate free spins bonus round that could have even more winning potential than the link and win feature!
During this mode, reels two, three, and four are merged into a single colossal reel containing giant 3x3 symbols that the game will interpret as 9 different symbols for payout purposes. Lining up a single symbol on reel one with the same symbol on the colossal reel will result in 25 four-of-a-kind payouts, and you can even retrigger this feature by landing a single scatter on the colossal reel!
I was surprised by just how fun this game was – even as I was finishing this review; I still wanted to keep on playing as I’d had some fantastic results in a short period of time! Sure, I was probably lucky, but if I can be lucky, then you can too – search this one out; it’s well worth a spin!
