Best New Online Slot Releases This Week - June 4th, 2026

Another week, and several new slots are available to play!

It’s been another huge week for slot releases, with developers spoiling British players with new titles to consider this week. We’ve seen many of the biggest studios release titles, including some refreshing old classics, while smaller developers have introduced new ideas to further expand the library online slot sites.

As usual, I’ve taken a look at all of this week’s newest releases and ranked my best options for you to consider, detailing the top UK online casinos to play them at!

Sanatorium Secrets

It might be some time away from Halloween and the scary times that it can bring, but Pragmatic Play don’t appear to be sticking to the holiday season with their release of ‘Sanatorium Secrets’.

The game offers plenty to be excited about, despite its dark, gloomy tone. The playing grid is a 6x4 matrix, allowing 4,096 ways to win! Bet ranges are wide, suiting players of all budgets, with volatility set to medium. This title’s RTP of 96.47% is in line with the industry average.

Play the game, and you might unlock a few features: special symbols and free spins. There are three special symbols to trigger: 1x4 Wild, 2x4 Wild, and Hook. The Wilds reflect the size they take up on the grid, while the Hook grabs all high-paying symbols on the same row, matches with them, and then converts them into 1x1 Wilds. If the Hook passes over the Wilds, you’ll see them be multiplied.

Caishen’s Cash Pots

Another release this week by Pragmatic Play, ‘Caishen’s Cash Pots’ is a strong title to consider this week. Using the multi-pot feature, this Asian-themed title features a simple gameplay premise adorned with the riches and wealth associated with gold, especially in Asian culture.

With 243 ways to win, the playing grid is a standard 5x3 layout. The math model has medium volatility, with an RTP of 96.49%. Still, up to 15x the bet can be won for 5 OAK matches.

You have the ‘Money Collect’ symbol that can appear on reels 1-4, with between 2x and 500x the bet available to claim. However, you must land a ‘Collect’ symbol on the fifth reel to win them. Land just one of these and all prizes can be obtained.

There are three scatters available: Phoenix, Dragon, and Tiger. These are collected; however on random occasions, a free spins round can be triggered. If this happens, you’ll receive 6 free spins, and each scatter becomes a modifier. They all act as multipliers with varying values and appear on specific reels. During the free spins, you may see Fish Symbols; these provide an additional +3 free spins and add random multipliers to the grid across 3-6 positions.

Razor Shark Jackpots

Adding to the collection of games already in the library, ‘Razor Shark Jackpots’ is the next installment for Push Gaming in this series. It uses many of the same mechanics, including the familiar mystery symbol that players of previous iterations will have enjoyed.

Using a 5x4 playing grid, there are 20 paylines, a medium math model, and an RTP of 96.38%. The graphics are of an expected quality and immersive enough to keep you engaged. Still, it’s that mystery symbol that can keep you hooked.

They can land in stacks of four and activate the ‘Nudge & Reveal’ feature, revealing regular paying symbols, Token symbols, or Golden Shark symbols. Token symbols can trigger the jackpot within the game, with up to 5,000x the bet available to win. Golden Shark symbols activate the Razor Reveal feature, where you can win cash prizes or trigger the free spins game, which continues as long as mystery symbols remain on the grid.
