Design And Theme
🖼️ Graphics
Under the Sea looks like an early-2010s 1x2Gaming release: simple 2D animation and bright marine symbols on a dark-blue backdrop. No ships or mermaids here, just shells, crabs, corals, and bubbles rising as the reels stop. The UI is old-school with “mechanical” bet buttons, but everything is clear. The mood is unhurried, like a slow dive along the reef.
🎶 Sound
A drawn-out synth “accordion” carries the soundtrack, aiming for undersea depth but landing a little dated and muddy. Wins and free-spin triggers are the same instrument turned up, which spikes the contrast. After a hundred spins, the loop grates. The mute button is the best upgrade.

Winning Combinations
Before you learn how to play Under the Sea in practice, check the payouts. We converted the paytable values (shown in coins per line) into x-multipliers by dividing by 25 active lines at a 1-coin/line stake. If you change the number of lines, the x-values scale accordingly.

Special Symbols
There are three special symbols plus one extra combo that affects balance more than regular lines.
- Wild (clownfish): substitutes for all symbols except the turtle (Scatter) and the crab (special symbol). Chooses the most valuable outcome when multiple wins are possible. Does not pay on its own, but often helps connect whelk or seahorse lines.
- Scatter (turtle): pays anywhere: 3 scatters — x7.2, 4 — x12.8, 5 — x40. Also triggers free spins: 5, 10, or 15 spins. All wins in the bonus are doubled, and 3+ scatters during free spins add more spins (retrigger).
- Crab: pays on active lines like a regular symbol: 3 — x1.2, 4 — x4, 5 — x8.
- Mixed Seafood: any line of three different sea-produce symbols (crab + scallop + whelk). Pays a fixed x6 of the total bet. Small next to the bonus, but fairly frequent.
Bonus Game
- Triggered by Scatters.
- A flat x2 multiplier applies to all wins during free spins.
- 3+ scatters in the bonus retrigger and add extra spins.
- Mechanics, symbols, and bets remain the same as in the base game.
RTP, Volatility, Max Win
RTP is 96.8%. Volatility is medium. The provider does not state a clear cap; some aggregators claim up to x1000, while a paytable-based estimate suggests around x800 per spin in the bonus (top symbol full lines on 25 lines, doubled).
Our Verdict
Under the Sea is a calm, retro slot: simple lines, x2 free spins, and an occasional Mixed Seafood payout. It does not try to surprise, which is part of the charm: jump in, spin, catch a bonus, move on. The downside is the fatiguing audio and a modest ceiling. Suits players who want a no-nonsense rhythm without dense rules. If you need pace and progression, look elsewhere.
If you want to stay underwater:
- Big Bass Bonanza — newer and punchier, with cash fish and levelled multipliers in free spins.
- Tombstone R.I.P — for those after a far more dynamic mechanic with escalating volatility and brutal multipliers.
