1429 Uncharted Seas Slot Demo

Updated September 3, 2025

1429 Uncharted Seas by Thunderkick is an online slot with a unique style, inspired by sixteenth-century nautical maps.
It has become a bit of a classic online slot thanks to its high RTP of 98.6% and low volatility, creating a low-risk gameplay for UK players.

Here you can try the 1429 Uncharted Seas demo for free, with no registration or deposit required, and explore all of its features!

Our verdict on 1429 Uncharted Seas – 8.9/10

This slot may not look like it, but it actually dates back to 2016. The years hardly show, thanks to solid gameplay and a truly distinctive design inspired by mid-millennium nautical maps.

Bonus features are limited: an expanding Wild and a Free Spins round. That makes it a fairly classic game, yet at the same time dynamic and strangely relaxing. The maximum win potential is “only” 670x your stake, which, for a low-volatility slot with frequent payouts, is still pretty decent.
It’s one of the best choices for players who enjoy long gaming sessions without too much risk. Plus, its RTP of 98.6% puts it among the highest RTP slots in the industry. 
Of course, for high rollers or those chasing big risks, there isn’t much on offer here. But for players who want to take advantage of casino welcome bonuses, or simply come away with more than they staked, 1429 Uncharted Seas is one of the best options out there.

5 reasons to play 1429 Uncharted Seas

As one of my favourite slots, I’ve spent many hours playing this title. Personally, I’ve picked out the five main reasons why I particularly enjoy 1429 Uncharted Seas.

  • Low Risk: The low volatility makes it one of the best options when I have a smaller budget, or when I want to boost my chances of meeting wagering requirements for casino welcome bonuses. Losses are usually minimal and, with a bit of luck, it’s easy to climb above your starting balance. This is helped, of course, by the 98.6% Return to Player and the low minimum bet of £0.10.
  • Beautiful Visuals: At first glance, 1429 Uncharted Seas impresses with a carefully crafted and striking design. The 16th-century nautical map theme is easily one of the most original you’ll find on the market.
  • High RTP: 1429 Uncharted Seas has often been named among the highest RTP slots at online casinos. This game’s RTP is truly impressive, standing at 98.6%.
  • Low Volatility: The game’s frequent payouts work in unison with the high RTP, creating a low risk gameplay that’ll please casual players and ones with smaller budgets.
  • Free Spins Bonus: Given the slot’s low volatility, being able to trigger up to 50 free spins usually results in a fairly solid win. The amounts are limited, but with almost every spin producing something, the efficiency of the feature is maximised.

How to play the 1429 Uncharted Seas Slot?

1429 Uncharted Seas is a simple 5×3 slot with 25 paylines and it’s suitable for both beginners and experienced players. The goal is to land winning combinations with at least 3 matching symbols aligned from the first reel, left to right. Before diving into its bonus features and symbols, let’s review a classic round.

Step-by-Step Gameplay

  • Set your stake
    Choose your bet amount before starting. The slot allows wagers from as little as £0.10 up to £5 per spin.
  • Start the game
    Hit the “Spin” button on the right to play. Wins are formed by landing at least 3 matching symbols in a row, starting from the leftmost reel. Open the paytable at any time to see symbol values and payouts.
  • Unlock Free Spins
    Land 3, 4, or 5 Compass symbols to trigger 10, 20, or 50 free spins. The feature can also be retriggered while it’s active, giving you extra chances to win.
  • Spin again
    After every spin, if you have won, it will be automatically added to your account balance, if not the game just settles. If you want to keep playing, hit the spin button again.

Symbols & Bonus Features

In 1429 Uncharted Seas, there aren’t that many symbols, but each one is beautifully inspired by seafaring in a different era. They are a mixture of sea creatures and nautical symbols in a creative hand drawn style. We can group them into three main categories:

  • High-value symbols: The Mermaid and the Kraken. The Mermaid is the most rewarding, paying up to 50× your stake for 5 of a kind. The Kraken (Octopus) offers up to 10× your stake.
  • Medium-value symbols: The various sea creatures/crustaceans pay between 0.8× for 3 and up to 6× for 5 of a kind.
  • Low-value symbols: The Sun, Moon, and Star icons, paying between 0.5× for 3 and up to 3× for 5 matching symbols.

There are two special icons to watch out for:

  • Expanding Wild (represented by the Ship): Appears only on reels 2, 3, and 4. When part of a winning combination, it expands to cover the entire reel and substitutes for all other symbols except the Scatter.
  • Scatter (represented by the Compass): Landing 3 anywhere on the reels triggers 10 free spins, while 4 or 5 Scatters increase this to 20 or 50 free spins.

Visuals and theme

Strongly inspired by 16th-century nautical maps, the graphics of 1429 Uncharted Seas are undoubtedly one of its strengths.
The sounds in the base game are very basic, but when you land a line hit, a Scatter symbol or a Wild, then you’re hit with a flurry of sound effects. The Scatter comes with a bell sound, a line hit has a short but fast musical interlude, but the biggest sound effect comes with a Wild. When the Ship Wild symbol creates a winning combination, a strong adventurous fanfare erupts as a sea creature lifts the boat to expand over the full reel. It’s almost cinematic and I love it. The character of the game is undeniable, making 1429 Uncharted Seas one of the most fascinating slots on the market, despite being released in 2016.

1429 Uncharted Seas’ RTP and volatility

Thunderkick’s 1429 Uncharted Seas stands out for its exceptionally high RTP of 98.6%. Combined with its low volatility, this slot is one of the least risky slot games in online casinos today. Of course, as we always remind players, the Return to Player (RTP) is theoretical. It’s calculated across millions of simulated spins and therefore cannot reflect individual player experiences. 

Low volatility follows the same principle: payouts tend to be frequent but smaller in size. In short, the key selling point of 1429 Uncharted Seas is that it’s perfect for players who prefer lower risk, even if it means the rewards aren’t sky-high.

That said, the game still offers a respectable maximum win of 670× your stake.

Play 1429 Uncharted Seas on Mobile

The mobile version of 1429 Uncharted Seas runs smoothly when tested on my iPhone 15.
The only drawback is in landscape mode, where the buttons on the right don’t stand out enough against the background artwork. Personally, I preferred playing in portrait mode, where the controls sit neatly below the reels, keeping the layout almost identical to the desktop version.

In terms of functionality, graphics, and audio, there’s absolutely no difference. The experience is seamless on all devices.

Final Thoughts on This Slot

Overall, I wouldn’t say that 1429 Uncharted Seas is “old”. It’s still quite pleasant to play, and its constant presence in various casinos, as well as in lists of the best online slots, confirms this.

The low maximum win potential may not excite high rollers. But, for the average player, a high RTP and low risk mean many things, including more chances to have fun and maybe win back a little more than they bet.
