Upcoming Slot Releases This Week – New Online Slots (June 1 – June 7)

Horror, ice, mythology, ancient riches, and a bayou full of frogs, this week refuses to settle on a single mood.

Pragmatic Play shows up twice, once dragging you into a decaying asylum where a Hook symbol rewrites the board mid-spin, and once returning to the Asian pot formula with a fourth pot that earns its place. Paperclip Gaming brings a frozen dragon lair where a 2x2 wild descends through the board absorbing multipliers as it goes. Hacksaw Gaming offers something warmer and more unhurried than their usual output, letting fortune wheels do the compounding quietly. And Titan Gaming sends a grinning bayou frog that expands, stacks multipliers up to 200x, and plays considerably harder than it looks.

Check out this week's new online slots — full details on RTP, volatility, max wins, and bonus features for every game releasing between June 1 and June 7.

Sanatorium Secrets (Pragmatic Play)

Release date: June 1

Pragmatic Play doesn't often go this dark. Sanatorium Secrets opens on a misty, wrought-iron gate with an ominous institution looming behind it; decaying stone, grey skies, barbed wire, the kind of place that looks like it was designed to keep things in rather than let people out. Spider-crawled playing card royals and four unsettling character symbols fill the reels. It sits somewhere between Silent Hill and Outlast in terms of visual tone, and it commits to that atmosphere completely.

The Hook is the symbol that makes the base game interesting. Landing on the outer reels, it drags across its row, pulling high pay symbols into wilds and doubling any multipliers it passes over. Combined with the tall wild symbols, 1x4 and 2x4 versions carrying multipliers up to 64x, a well-timed Hook sweep can restructure the entire board in one motion.

Before free spins begin, a hold-and-win Puzzle round plays out. Puzzle pieces lock onto reels 2–5, each one resetting the spin count and awarding an extra free spin. Fill a reel completely and the premium symbol above it turns wild for the entire bonus. It's a setup phase that determines how loaded the free spins round actually is before the first spin lands.

At 96.47% RTP, medium volatility and 10,000x max win, Sanatorium Secrets is more measured than its horror aesthetic suggests, but the Hook mechanic and Puzzle setup give it a mechanical identity that's harder to shake than most Pragmatic releases.

Dragonspire Frostfall (Paperclip Gaming)

Release date: June 1

Dragonspire Frostfall is Paperclip Gaming's most visually polished entry yet, and a significant step up from the original Dragonspire. The setting is a frozen dragon lair, crystalline blues, ornate gold-trimmed frames, icy spires stretching behind the board, and a 2x2 dragon wild that tumbles down through the grid carrying multipliers in its wake. It looks carved rather than drawn, and the cold fantasy aesthetic holds together from background to symbol set without overcrowding the screen.

The cluster pays system runs on tumbling wins, but what keeps it from feeling standard is the powerup system. Two board positions activate each spin, and any winning cluster touching them triggers one of three effects once the tumbles settle, Wild Spawn places 2 to 5 random wilds, Clear removes all low-value symbols, and Freeze locks a sticky wild in place. Those Frozen Wilds then feed into Dragon's Call, a side feature where the 2x2 dragon descends through the board row by row, absorbing locked multipliers as it passes.

Dragon's Call X pushes that further, the dragon enters with a multiplier starting at 25x and reaching up to 100x, which is the screenshot's 100x wild in action. When that lands during a loaded board with Frozen Wilds already placed, the tumble chain that follows can move quickly toward the 20,000x ceiling.

At 96% RTP and high volatility, Dragonspire Frostfall rewards patience in the base game and pays it back properly when the dragon arrives loaded.

Rise of Fortuna (Hacksaw Gaming)

Release date: June 4

Rise of Fortuna is a different mood for Hacksaw Gaming, an ancient Roman-themed slot that's warm and unhurried. Warm and unhurried, Fortuna herself sits cross-legged in a golden circle to the right of the screen, columns frame the reels, clouds drift behind ancient architecture. It's classical mythology rendered in a style that invites you to settle in rather than brace for impact.

The Fortuna Wheels are what the game is built around. Three wheel symbols can land on the leftmost, middle, and rightmost reels, Regular, Super, or Epic, each spinning a 12-segment wheel that awards either additive multipliers building a Cash Prize Bar, or multiplicative values that compound whatever's already accumulated there. The distinction matters. Landing an additive 100x is one thing. Landing a multiplicative 20x on top of an already loaded bar is another entirely.

The jackpot segments sit on every wheel type, Mini at 25x, Major at 100x, Mega at 500x, and the Max Win at 10,000x, adding a jackpot dimension that keeps each wheel spin meaningful beyond the standard multiplier reveals.

Three bonus tiers escalate wheel frequency and quality. Fortune is Blind guarantees three Fortuna Wheels per spin, which at 10 free spins with multiplicative values compounding throughout is where the ceiling becomes genuinely reachable.

At 96.28% RTP and medium volatility, Rise of Fortuna is one of the more accessible games Hacksaw has released recently, approachable without feeling lightweight.

Caishen's Cash Pots (Pragmatic Play)

Release date: June 4

Caishen's Cash Pots sits comfortably in Pragmatic Play's Asian-themed pot slot lineage, warm reds and golds, treasure rooms overflowing with coins, Caishen himself flanked by the Fortune Kids that seem to show up in every game of this type. It's familiar territory visually, and it doesn't pretend otherwise. What it does do is add a fourth pot to the formula, which opens up the multiplier system in ways the previous entries didn't quite reach.

The core is straightforward. Money symbols land on the first 4 reels carrying values of 2x to 500x, and a Collect symbol on the rightmost reel sweeps them all up in one hit. Three scatter types — Phoenix, Dragon, and Tiger — charge their respective pots above the grid, and when free spins trigger, whichever pots are active add multipliers to their associated reels. Stack all 3 and every reel on the board is sitting under a position multiplier before a single Money symbol lands.

The Fish pot is the new addition. When Fish symbols hit during free spins, the pot randomly applies multipliers of 2x to 5x across three to 6 grid positions, compounding whatever's already there and adding spins in the process. It's not a radical departure, but when it fires on a board already loaded with reel multipliers, the difference shows up in the totals.

At 96.49% RTP, medium volatility, and a 10,000x max win, Caishen's Cash Pots is exactly what it sets out to be, a refined version of a formula that already works, with one extra layer that earns its place.

De Frog (Titan Gaming)

Release date: June 4

Titan Gaming brings something deceptively cheerful this week. De Frog is set in a sun-drenched bayou, lily pads, cypress trees, dragonflies, muddy boots, and a grinning frog that takes up the entire wild symbol. It's bright and loose in a way that makes the mechanical depth underneath it easy to underestimate.

The De Frog wild is the centerpiece. It lands one per reel, expands downward when it's part of a winning combination, and reveals a random multiplier from 2x all the way up to 200x. When multiple De Frog symbols share a win, their multipliers stack rather than compete. That's a significant detail, a board with two or three loaded frogs contributing to the same payline can move totals very quickly.

The bonus structure runs through a Progress Ladder mechanic. During free spins, De Frog landings highlight reels, and collecting five bonus symbols on that ladder triggers a Special Spin where every highlighted reel is guaranteed to land a De Frog. Pond Party resets those highlights after each Special Spin. Sticky Tongue keeps them persistent, meaning the highlighted reels carry over, and the board stays loaded with guaranteed wilds for the entire bonus.

The Bonus Buy Battle mode lifts the ceiling to 50,000x and pits you against an opponent in a winner-takes-all format. Win and you take both pools. Lose and you walk away empty.

At 96.01% RTP and high volatility, De Frog earns more attention than its cheerful exterior suggests.

Sanatorium Secrets is this week's pick, and it earns it through mechanics rather than spectacle.

Dragonspire Frostfall has the higher ceiling, Rise of Fortuna is the most accessible of the three, but Sanatorium Secrets is the one that keeps revealing layers the longer you play it. The Hook reshapes the board quietly in a single motion. The tall wild multipliers carry up to 64x. And the Puzzle round that runs before free spins even begin means no two bonuses start in the same shape, the setup phase determines everything.

With a 96.47% RTP and a 10,000x max win, it doesn't shout about what it can do. It just keeps doing more than you expect.

A crumbling asylum, a frozen dragon lair, a Roman goddess, a treasure room full of pots, and a bayou frog with a 200x multiplier, this week doesn't explain itself, it just delivers.

Sanatorium Secrets keeps revealing layers the longer you play it, the Hook fires at the right moment and the board looks completely different. Dragonspire Frostfall is measured until the dragon arrives loaded, and then it isn't. Rise of Fortuna asks you to hand control to the wheels and sit with that, which is either appealing or uncomfortable depending on your temperament. Caishen's Cash Pots adds one new piece to a formula that already worked and lets it do exactly what it's supposed to. De Frog looks like the week's most casual entry until the Sticky Tongue bonus kicks in and the frogs stop leaving.

Five different bets on what keeps a player engaged. All of them land differently.
