Betsoft has had a busy few months. Four of the five slots on this list came out between July and September 2026, three under the studio’s story-led “THE Series” banner, and the fifth is a Hold & Win favorite that still posts the best RTP of the group. Here’s what each one does and who it suits at SplashCoins.

Good Girl Bad Girl 2
The newest of the lot, and the wildest ride. Good Girl Bad Girl 2 arrived on September 10 as a heaven-versus-hell sequel, featuring 5 reels and 20 paylines.
Battle Wilds are the core of it. Wild and Gold Wild symbols expand whenever they’re part of a win, then duel. A regular Wild duel can hand out multipliers up to 100x, and a Gold Wild duel pays either a multiplier or a trip straight into Hold & Win.
There’s a Grace Pot too. Wilds collect in it, and at random it can tip over, throwing 6 to 12 bonus symbols onto the grid and starting Hold & Win with three respins. Free spins come from scatters: 10, 15, or 20 of them depending on whether three, four, or five land, with expanding wilds staying sticky throughout.
The catch is the math. Very high volatility, a 23.59% hit rate, and the lowest RTP here at 95.81%, so quiet stretches are part of the deal.

THE Oil Barons
Big grid, big ceiling. Betsoft lists a top prize of 12,500x for THE Oil Barons, and it plays on a 5×5 layout with 15 paylines.
Three separate bonus rounds sit behind three different trigger symbols. Struck Oil gives 10 free spins with wilds that lock in place. Contract Duel also runs for 10 spins, but here VS symbols stretch across a whole reel, show two competing multipliers, and the winner applies while that reel turns fully wild.
The Gusher is the strange one, in a good way. Stage one is three respins with only wilds, multipliers, and blanks on the reels, and each new wild or multiplier resets the count. Stage two then scatters everything collected across three free spins. It’s a 96.29% RTP game with a 19.18% hit rate, the lowest on this list. Patience required.
-
THE Robbery
A steampunk Old West heist, and probably the easiest of the three “THE Series” games to pick up. THE Robbery went live on July 16 with 243 ways to win, climbing to 3,125 in free spins.
Most of the action runs through coins. Land a coin and a collect symbol together, and the Collect Coin Feature fires, shooting out random coins with multipliers from 2x to 10x. Even without a collect symbol, there’s a route in, since a winning combination across all five reels sweeps up every coin value on screen.
Coins and collect symbols also feed The Vault, which can set off the collect feature at random. Free spins award 6, 10, or 12 rounds for three or more scatters, and extra +1 Spin and Expand symbols can appear during play.
RTP is 96.06%, volatility is high, and the hit rate is 25.89%. Players who enjoy this style will find plenty of similar options in our guide to the best sweepstakes slots.

Ultimate Dragon Inferno Hold & Win
The veteran. It dates back to November 2024, yet it has the highest RTP of the five at 96.58% and the friendliest hit rate at 28.46%, which makes it the natural pick for longer sessions.
The base game is a tidy 5×3 with 243 ways. Hold & Win is where it opens up: collecting bonus symbols over three respins unlocks closed-off parts of the screen, growing the play area to as much as 10×6, with prizes ranging from Mini to Grand.
Every bonus symbol in the base game flies into a Cash Pot above the reels, and that pot can trigger either Hold & Win or a Pick Bonus, a simple match-three for one of four prize tiers. Reel three has its own trick: a partial wild stack that nudges up or down to fill the reel. Stacked mystery symbols round it out.

THE Gem Master
Set in a jeweler’s workshop, THE Gem Master is the calmest-looking game here, though it’s still rated high volatility. It launched on July 2 on a 5×4 grid with 20 fixed paylines and a 96.10% RTP.
Respins are the main event. Six or more bonus symbols start them; new bonus symbols and “customer multiplier” symbols lock in, and the counter snaps back to three each time. At the end, the game combines all those customer multipliers and applies them to the collected bonus values, which is where the bigger results come from.
Free spins require three scatters, and bonus and wild symbols appear more often while they run. There’s also a Bet Booster option that raises the chance of triggering either feature.
Which Betsoft Slot to Try First
Ultimate Golden Dragon Inferno is the steadier choice, on RTP and hit rate both. THE Oil Barons and Good Girl Bad Girl 2 are for players comfortable with long gaps between bigger hits, while THE Robbery and THE Gem Master sit somewhere in the middle.
Betsoft builds a Buy Bonus into all five, though purchase features aren’t always switched on at sweepstakes casinos, so it’s worth checking each game’s info screen at SplashCoins before starting.
