Colossal Splash Deep Dive Symbols and Design
The Colossal Splash Deep Dive game has a bright and colourful theme, with impressive graphics which make it clear that this is a newly released slot (April 2025, to be exact). The orange squid bobbing up and down to the left of the reels has an almost 3D look to it, and bubbles regularly float up from the bottom of the game screen.
The soundtrack has a relaxed, slightly beachy vibe that fits the theme quite well. If it’s not to your taste, you can easily mute it.
Let’s take a closer look at the symbols on the reels in the Colossal Splash Deep Dive slot. The full paytable can be by clicking the golden cog at the top right of the game screen and pressing the ‘i’ button.Colossal Splash Deep Dive logo5 symbols = 5x bet4 symbols = 2x bet3 symbols = 1x bet

Colossal Splash Deep Dive Bonus Features
The Colossal Splash Deep Dive slot game has a number of special features to explore. Here’s some more information about them:
Turbo Reels
Underneath the reels you’ll see three dials, or Turbo Reels. The dials can randomly move on each spin to signal different functions. The multiplier dial will multiply any wins (for that spin) by the number the dial reaches (up to 10x).
The bonus dial can determine which level of the bonus round you trigger (if the bonus is activated on the same spin), and the split reels dial can split up to five reels to double the number of symbols.
Deep Dive Free Spins
Three or more Bonus squid symbols award the Deep Dive Free Spins Bonus. The number of spins you will receive (up to 25) depends on how many symbols triggered the round, and which level of the bonus was awarded.
The bonus round also has a Wild dial which can add extra Wilds to the reels for more chances to win. Pearl Boost symbols can move the squid along the trail at the top of the reels during Free Spins, with the potential to unlock additional spins.
Colossal Splash Deep Dive Final Thoughts
Colossal Splash Deep Dive is an engaging slot game with a lighthearted underwater theme. It’s clear that Light & Wonder have put some thought and effort into the design, and the crisp visuals and colourful theme mean that this slot looks great. The Turbo Reels mechanic is a fun feature that I haven’t seen too often before, and the trail element of the bonus game adds another layer of excitement to the gaming experience.
Although I enjoyed playing the game, the RTP of 94.14% is a little disappointing. The maximum win is £250,000, but it was difficult to find out what this translates to in terms of bet multipliers. All in all, this is a fun slot game with enough bonus features to keep things interesting.
