Slots developer RubyPlay is making its way to a real money online casino near you, starting with BetRivers and FanDuel in New Jersey. Some of RubyPlay’s content was already available in the US through Light & Wonder, but it’s now independently licensed and starting to strike its own deals.
What does that mean for US casino players? For one thing, it means RubyPlay is making content geared specifically for this market, like Diamond Explosion Patriots, a star-spangled slot that’s unmistakably pitched at American players.
There’s also going to be a lot more RubyPlay content at partner casinos in general. Although only FanDuel and BetRivers have its content for now, other deals are on the way. Aside from New Jersey, you’ll soon find RubyPlay slots in Pennsylvania and Delaware through those same casino brands. Michigan and West Virginia are coming after that.

Diamond Explosion, Immortal Ways, and other unique mechanics
Every slots developer’s approach is a little different. RubyPlay’s focus is on series of online casino games that share a unique mechanic in common. Its most popular franchises are Diamond Explosion and Immortal Ways.
Diamond Explosion series: bigger blocks equal bigger wins
Diamond Explosion games have a bonus feature that, obviously enough, uses special Diamond symbols. Spinning at least six of these starts a respin bonus round. That can be achieved from the base game, but it’s usually easier from within free spins because there are extra Diamonds on the reels.

The Diamonds triggering the respins lock in place, and each additional spin brings with it the chance to collect more. It feels a lot like the trendy cash-on-reels respin mechanic, except the Diamonds don’t have a fixed cash value.
Instead, the goal is to form bigger and bigger blocks of Diamonds. For instance, a two-by-two square is worth more than four individual Diamonds, and a three-by-two rectangle is worth even more. A three-by-three square becomes a giant, spinning bonus reel offering the chance to win one of four tiers of jackpots.
Diamond Explosion Patriots is the first game in this series available in the US and it’s at both BetRivers and FanDuel. It’s a straightforward presentation of the core Diamond Explosion mechanics, chock full of stars, stripes, bald eagles, and of course a red-white-and-blue color palette. Every Wild symbol also has the potential to trigger a jackpot bonus round.
Immortal Ways series: an ‘always-on’ bonus feature
Immortal Ways games are six-reel, all-ways-pay video slots with a neat cash-on-reels bonus feature that carries over from spin to spin.
The first and last reels are four lines tall, while the middle four are five lines tall. Combined with the all-ways-pay mechanic, that gives the game 10,000 paylines! Naturally, that means a lot of volatility, and big wins when you stack up a lot of matching symbols on adjacent reels.
The middle four reels are split into two grids of ten symbols each: one for Reels 2 and 3, and one for Reels 4 and 5. Any of those reels can produce Coin symbols, which stick in place for a minimum of three more spins. Any additional Coins landing in the same grid reset the counter. If you can fill the entire grid before the Coins disappear, you win the total amount showing on them. There are also special Wheel Spin coins that have a large and randomly-determined value, perhaps even a jackpot trigger.
The Coins are a mixed blessing, which is what makes Immortal Ways games interesting. You can’t form winning paylines with a Coin symbol, so the more of them are stuck to the reels, the fewer of your 10,000 paylines can contribute to a win. On the other hand, filling a grid and collecting the Coins is guaranteed to be a big win.
So, when you don’t have many Coins on the reels, you’re hoping for stacked symbols and a big multi-payline win. Once you have a lot of Coins, you’re hoping for more, to keep your hopes alive of filling a grid. Either way, it’s exciting.
FanDuel and BetRivers each have an exclusive deal for one game in this series: you’ll only find Immortal Ways Cleopatra at FanDuel, and Immortal Ways Lady Moon is exclusive to BetRivers. (BetRivers also has a couple of other games in the series as non-exclusive titles: Immortal Ways Champions and Immortal Ways Sweet Coin.)
