1429 Uncharted Seas Slot Review
Slot Developer
1429 Uncharted Seas is a Thunderkick game. This Stockholm-based studio has been in business since 2012 and produces UK favourites like Midas Golden Touch and Pink Elephants 2.
Slot Theme and Story Line
Get ready to set sail! This game is themed around an ancient map, where sea monsters lurk, and there are plenty of hidden treasures for you to uncover. It’s a totally unique theme that I haven’t seen in all my time doing slots reviews.
Reels, Rows, Paylines
1429 Uncharted Seas has five reels, three rows, and 25 fixed paylines, which are active every time you spin. Wins pay out in the usual way, on adjacent reels from left to right on a payline.
RTP & Volatility
The 1429 Uncharted Seas RTP is one of the standout features of this game - it’s set at 98.6%. The game has low volatility, so wins tend to pay out relatively frequently.
Betting Range
The lowest possible bet amount on 1429 Uncharted Seas is just £0.10, and here in the UK, the maximum pound slot limits are set at £5 per spin.
Max Win Potential
1429 Uncharted Seas has quite a low max win amount of just 670x your stake. Even at the top UK limit of £5, that only works out to £3,350 if you manage to get very lucky with your symbols.
Jackpot Element
There’s no fixed or progressive jackpot in the 1429 Uncharted Seas slot game. You can get the maximum payout by landing high-paying symbols on the grid when you spin the reels.
Graphics & Sound
The look and feel of this game is totally different from the vibrant colours and neon lights you’ll have seen on other slot games. The colour palette is muted, and the hand-drawn map style is completely unique. On the downside, the soundtrack is somewhat lacking - there’s no background music and the sound effects only really kick in when you win.

Pros and Cons
Pros
Very high RTP of 98.6%
Excellent visuals
Bonus round with up to 50 free spins
Cons
Low max win of 670x
Limited special features
No progressive jackpot
Game Symbols and Payouts
Regular, themed symbols pay out line wins, and while 1429 Uncharted Seas is known for simple gameplay, there are a few special symbols to look out for.
Regular Symbols
The mermaid and other mythical creatures like the giant squid pay out bigger wins, while coins award smaller payouts. Let’s take a quick look at the payouts for a £1 spin.
| Symbol | Match 3 | Match 4 | Match 5 |
|---|---|---|---|
| Mermaid | 4 | 8 | 50 |
| Turtle | 1.20 | 3 | 10 |
| Kraken | 1.20 | 3 | 10 |
| Lobster | 0.80 | 1.50 | 6 |
| Sea Monster | 0.80 | 1.50 | 6 |
| Sun, Moon or Stars Coin | 0.50 | 0.80 | 3 |
Special Symbols
- Wild symbol: The special expanding wild symbol appears on reels 2, 3, and 4, and they’ll expand to cover the whole reel when it’s part of a winning combination. Wilds substitute for everything except the bonus symbol.
- Bonus symbol: Get three or more bonus symbols to enter the free spins round. Depending on how many bonus symbols land, you’ll get up to 50 free spins.
1429 Uncharted Seas Demo Version and Free Play
True to its theme, you’re going to have to be a bit of an explorer to find UK slot demo play for this game. A lot of top online slots sites (like BetMGM) don’t carry 1429 Uncharted Seas free play, but at least the Thunderkick website has it. This game looks very different from your standard slot, and even some of the gameplay is unique, so trying a demo is the ideal way to make sure you actually like the game before you play for real. Who knows - maybe you’ll prefer the classics.
1429 Uncharted Seas Bonus and Key Features
Over a decade ago - when 1429 Uncharted Seas came out - games weren’t as packed with special features as they are today. Things like nudging wilds features, progressive jackpot races, and even multipliers were pretty rare. Nevertheless, the1429 Uncharted Seas bonus features aren’t too bad.
Expanding wilds
Lots of slots have wild symbols to help complete winning combinations, but in this one, the wild takes the form of a ship being attacked by a monster, and it expands to cover the whole reel if it’s part of a winning combination.
Expanding wilds
Free spins round
Land three, four, or five scatters anywhere on the grid to get 10, 20, or 50 free spins, respectively. The bonus game works the same way as the base game, so unfortunately, there are no extra features there. But I was pleased to see that there are up to 50 spins up for grabs.

Mobile Play Experience
Mobile Play Experience 1249 uncharted seas
The 1429 Uncharted Seas mobile game works very smoothly, especially for an older slot. The animations run well on mobile, and it looks surprisingly modern for a slot made in 2014 (and set in around the 1400s). The grid takes up about half of the screen, which means that the spin button and stake options are very easy to see and use. But that also means that the grid is a little smaller than I like to see. Similarly to on desktop, there isn’t much in the way of a background, but the themed grid that looks just like a map does all the heavy lifting, so it’s not needed.
1429 Uncharted Seas Expert Tips & Strategies for Winning
1429 Uncharted Seas is quite a simple game, with fair and random results. But I picked up on a few things while I was playing, which I’ll share with you here.
Think about your stake amount: 1429 Uncharted Seas in the UK has one of the highest RTP percentages of any game, plus the volatility is low. You should get quite regular, small payouts, so it might be worth upping your stake.
Wait for the free spins round: There are up to 50 free spins up for grabs, and in my experience, this was the best possible way to bag a big payout, even if the free spins round doesn’t have any extra features.
Capitalise on slots bonus offers: Games with very high RTP like this one are often excluded from welcome bonus slots offers. But it’s always worth checking, because if the game is included in the promo, it could bag you a better payout than other games.
1429 Uncharted Seas Alternative
While you might not find many games where the RTP is as high as on 1429 Uncharted Seas, I found a couple of other options that you might want to explore while you’re at it.
Blood Suckers: If you want to stick with high-RTP games, this one pays out up to 98%. This vampire-themed game comes with wilds, free spins, and it’s a low to medium volatility slot.
Beat the Beast: Kraken’s Lair: This is another Thunderkick title, also with a sea monster theme. The RTP is lower, at 96.12%, but the game comes with high volatility for extra thrills.
SportsBoom Suggests – Is 1429 Uncharted Seas Worth Playing?
Personally, I’m a huge fan of this game. It’s one of the highest RTP slots around, and even though the special features are quite modest, the 50 free spins round is a lot bigger than I’ve seen on most slot games. Would I like to see better features, like multipliers, tumbles, or progressive jackpots? Sure. Would I recommend the game exactly as it is? Absolutely! I understand that some players might be looking for bigger thrills, so make sure you try a 1429 Uncharted Seas demo, or claim a free spins no deposit UK bonus so you can test it out for free.
