Top 10 new online slots for October 2025
10. Crown Strike
Crown Strike: Hold and Win comes with the expanded grid allowing up to five Striking Crown symbols to land on the middle reel only for increased win potential.
In the 15-payline game, the Striking Crown symbols act as a Collect Feature during both base and Bonus Games, accumulating the value of all bonus symbols and adding them to the total win.
Bonus symbols appear with set multipliers of up to 12x, or as one of four in-game Jackpots symbols worth between 15x (Mini) and 1,000x (Grand).
9. Coin Tornado
Built around five fixed paylines, Coin Tornado heightens anticipation with Bonus Coins that activate the Hold & Win Bonus Game. Landing six or more Bonus Coins secures them in place, while jackpots and multipliers whirl through the storm.
The Fake Collect mechanic pulls coins into the tornado before flinging them back onto the reels to complete the Bonus trigger in dramatic style.
Additional features include Collect and Multiplier symbols in the base game, as well as Buy Bonus and Super Bonus options for players eager to jump straight into the storm.
8. Mermaid’s Treasure Trove
In Mermaid’s Treasure Trove, landing clusters of 5-15+ matching symbols pays out up to 150x in the base game, where winning combinations leave behind wild multipliers for the following tumble.
Each subsequent tumble win featuring the wild multiplier increases its value by +1x and moves it to an adjacent position on the grid. When two or more multiplier wilds contribute to the same win, their values are combined.
Landing three to seven scatters triggers the bonus game with 10-18 bonus spins, with each additional scatter that hits during the feature awarding one extra spin. During the feature, all multiplier wilds remain present on the grid throughout.

Adding to the excitement, Vulcan’s Lucky Wheel gives players the chance to spin for one of the five jackpot prizes whenever non-winning coin or jackpot symbols appear.

Spinomenal’s Spooky Halloween is set within a forest cloaked in fog, surrounded by twisted trees and glowing candles illuminating the 5x4 layout.
An assortment of classic Halloween icons form the medium symbols, featuring a witch’s hat, a ghost, a black cat, and a bubbling green potion.
Landing three or more scattered bonus spins symbols unlocks the bonus spins game. Three symbols awards 10 spins, while four symbols unlock 25 spins, and five or more summon 100 spins.
Once bonus spins are active, a stacked wild appears on one random reel for every spin, enhancing the chances of landing big wins.

Led by the sinister yet charming Joker, Trick or Treat Joker blends spooky visuals with classic fruit symbols for a twist on conventional gameplay. Pumpkins, cobwebs, bats, and glowing symbols create a haunting setting for an eerie adventure.
The game’s main feature is the Wild Respin mechanic. When a wild appears on reels two, three, or four, it expands to cover the entire reel and triggers a bonus respin, locking in place while the other reels spin again.
