1429 Uncharted Seas

1429 Uncharted Seas is a 5-reel, 25 payline mythical-themed slot developed by Thunderkick. This impressively designed low volatility slot boasts features and mechanics such as expanding wilds and a free spins bonus that can see players pick up 50 free spins in one go!


This nautical-inspired slot, like all Thunderkick games, is absolutely beautifully designed and we genuinely cannot praise it enough. The game was made to look like a hand-drawn 15th-century map that a great adventurer might have used as they set out on the high seas in search of riches, new land and opportunities. 

Symbols in this slot are as follows: Stars, the moon, the sun, a sea monster, a giant lobster, a squid, a snapping turtle and a mermaid. The special bonus symbol is a compass whilst the wild symbol is a boat that can expand, revealing a menacing sea creature.

If you really squint and take a good look at the game screen whilst the reels aren't spinning you'll notice that a shadow of a cabin window is being cast upon the map, which moves up and down as the boat sways from left to right, it's a nice little touch. 

When players trigger the bonus game players are shown some wonderful art of a boat sailing in a storm and the entire game reels go darker and thunder and lightning strikes inbetween each spin. 

When it comes to how this game sounds, it's pretty bland but it does fit the aesthetic. There is a pretty average soundtrack and players can hear the sound of the sea, however, it's not overly exciting.


1429 Uncharted Seas is one of those online slot games that doesn't really look like an online slot game, but that's not particularly a bad thing, it's actually a testament to how well designed this Thunderkick slot is! 

The game's action bar runs across the bottom of the game screen underneath the reels, there are two buttons on the left-hand side of the game screen an expanding game settings menu and a mute button. On the right-hand side of the action bar is a stake selection tool, an autoplay button (that allows players to set up to 5000 automated spins) and the spin button.

Win Potential

First and foremost we have to just say wow... 1429 Uncharted Seas has an RTP of 98.5%, which is absolutely unheard of, this is easily one of the highest RTP's you'll find in any game on Slot Gods. On the other end of the scale, this low volatility slot has a maximum win potential of 670x the player's stake which is pretty disappointing. 

Our Verdict

This is a unique and beautifully designed slot with generous bonus features and an absolutely fantastic RTP.... That being said we're really struggling to look past that low win potential, it's all good and well bringing us frequent wins (we'll never complain about this!), but we'd really love to pick up a bit more than just 670x our stake!
