King of 7s Description
Octoplay is a game studio known primarily for creating fruit-style online slots and those featuring the Hold & Win engine. In the first quarter of 2026, this provider set loose on the world Kings of 7s, which is another one of its retro-inspired reel-spinning titles.
This is an original game, and one that can be compared to entries in Reel Time Gaming’s 7s Deluxe series or Octoplay’s own 777 Hot Reels, but has a more fun presentation. It boasts a cartoony royal motif that goes over what is pretty standard 5x3 gameplay enhanced with basic wilds and a Free Spins bonus that can involve some nifty modifiers.
While this will admittedly not be among the most exciting online slots in any casino lobby, it is still a decent pick for those into retro spinners and casual players.

King of 7s Bonus Features
As mentioned in the intro, the King of 7s slot machine, essentially, only has one bonus round, its Free Spins one, which can be activated through two different methods. We explain how below.
King of 7s’ Wilds
The substitution symbols in these games are unique in that they can only show up on the fifth, third, and first reels, and only one per reel on a spin. When they hit, they throw a coin into the pile above the game grid, giving you a shot to trigger the King of 7s Free Spins bonus, which we will tell you about below.
Like in most other modern spinners, this coin accumulation is only for entertainment purposes. There is no set milestone that you need to hit to activate the Free Spin feature, which happens at random.
Free Spins
The standard way of coming into this game’s Free Spin mode is if three scatters stop in view, which provides you with seven on-the-house spins. In this feature, your aim is to unlock the three rounds that sit above the symbol layout. You do this by landing wilds, and for each unlocked crown, you get another seven on-the-house spins, plus a modifier.
Here is what each of the crowns brings to the table when unlocked:
- The first crown – Applies a 7x multiplier to all prize combos.
- The second crown – Expands wilds to cover entire reels.
- The third crown – Makes wilds sticky.
