1429 Uncharted Seas Slot RTP, Details & Wager Limits

Reels/Paylines: 5 reels + 25 paylines

Stakes Range: 10p to £100 per spin

RTP: 98.6%

Max Win: 670 x bet

The 1429 Uncharted Seas slot comes with 5 reels, 3 rows and 25 paylines. Simply, you can form a winning combination by landing 3, 4 or 5 matching symbols across any of the 25 paylines, beginning from reel 1.

Like with most Thunderkick slots, you can play from 10p to £100 per spin. To select your bet, click on the casino chip where all available stakes are shown clearly. There is an option to play in Auto Play mode where you can opt for 5 to 5,000 auto spins. You can stop Auto Play if the Bonus Game feature is activated. This option isn’t available to UK players.

The 1429 Uncharted Seas RTP is 98.6% which means the game has achieved cult status amongst slot players. You read that right. For every £100 you stake, you’ll win back £98.60 giving the casino a 1.5% edge/margin. Couple that with the low variance and your bankroll should go a very long way. The high return rate makes this game a high RTP slot.

Variance wise, 1429 Uncharted Seas is low meaning plenty of frequent wins of a smaller nature. The occasional big win will land if you manage to get 2 or 3 expanding wilds simultaneously. Expect a win every 2.42 spins on average as the hit frequency rate is 41.2%.

The max win is 670 x your total bet but you should in theory be able to win 1,250 x your total stake (by filling the reels with the highest value symbol and/or wilds)

1429 Uncharted Seas slot - base game

The ocean has provided fertile ground for slots developers. The 1429 Uncharted Seas online slot is visually different and stunning. While many pirate-themed slots have adopted a cartoon style, 1429 Uncharted Seas is much more weighty fare focusing on the early years of seafaring exploration.

The reels look like a beautifully designed map from the middle ages. It’s unlike anything you’ve seen before. You head back to 1429 where you explore the unknown oceans to discover what lures deep below the surface.

The symbols are superbly drawn and are vastly different to the imagery usually found on most slot reels. Shadows flow across the screen adding to the impression of a rolling seascape. The high class visuals are accompanied by a sweeping, orchestral soundtrack, complete with bells, cannon blasts and cracks of thunder. It really does look and sound an absolute delight.

With the sounds of the sea as you spin the reels, symbols include stars, suns and moons. You’ll also see various sea creatures including purple sea serpents, orange lobsters, red krakens, giant green turtles and yellow mermaids. The mermaid is the highest paying symbol and offers 4, 8 or 50 x bet payouts for 3, 4 or 5 in combination.

There is a Ship Wild symbol which appears only on reels 2, 3 and 4. It replaces all symbols bar the Compass Scatter and expands only when part of a winning combination.

1429 Uncharted Seas can be played on desktop, mobile and tablet devices as standard. The Swedish game studio (Thunderkick) ensures that all their games are multi-platform as they use HTML5 technology. Thunderkick has created something pretty special which transpires well on smaller, smartphone devices.

1429 Uncharted Seas Bonus Features

1429 Uncharted Seas comes with 2 main bonus features. There’s an expanding wilds feature as well as a Bonus Game feature where up to 100 free spins are possible, along with expanding wilds.

Expanding Wild feature

The ship is the wild symbol. When it appears on any of the 3 middle reels (reels, 2, 3 or 4) in a winning payline, it will trigger the Expanding Wild feature and transform into an expanding wild. The wild fills up the reel to give you a wild reel. You can get up to 3 wild reels per base game spin.

Bonus Game feature

Next is the Bonus Game feature which are triggered by the Compass Scatter symbol. 3, 4 or 5 anywhere on the reels will give you:

Compass Scatters Free Spins
3 10
4 20
5 50

It’s possible to trigger even more free spins if the Compass Scatter reappears during the feature. Up to 50 free spins can be re-triggered here (with up to 100 in total).

Finally, the Expanding Wild feature applies meaning that you could play with 3 wild reels per free spin.

1429 Uncharted Seas Slot

1429 Uncharted Seas is a legendary slot by Thunderkick which offers unique design, simple gameplay and an exceptionally high 98.6% RTP rate.

Pros
  • Very high 98.6% RTP rate
  • 41.2% hit frequency rate
  • Unique design/graphics
Cons
  • Low max win potential
  • Only 2 bonus features

Released in April 2014, the 1429 Uncharted Seas slot is unique in the way it looks visually. Taking place on an olde worlde-style map, it looks very different to other slot games and has it’s own charm. In terms of sounds, the win noises do remind me of Gonzo’s Quest (NetEnt).

The bonus features are pretty simple with expanding wilds awarding up to 3 wild reels per base game spin. This applies in the Bonus Game feature where up to 100 free spins can be won in total.

The reason that 1429 Uncharted Seas has achieved cult status is due to it’s 98.6% RTP rate. At the time of writing, it ranks third on the best RTP slots list.

Low variance, this makes for a great choice for players who want to maximise playing time with their bankroll. You’ll also land winning combinations frequently (41.2% hit frequency rate). It does come with 670 x bet max wins which isn’t very high but the RTP and high win rate compensates.

If you fancy heading to sea, there are plenty of options. Those that feature krakens include Thunderkick’s very own Beat the Beast: Kraken’s Lair (7,777 x bet max wins) and Pragmatic Play’s Release the Kraken (10,000 x bet max wins).
