Tumblin' Dublin

Tumblin' Dublin Overview

Tumblin' Dublin is an Irish-themed slot from NetGame, released on 6 October 2023 according to the studio's own game database. A leprechaun with a lantern and a pot of gold watches over a 5x5 grid with 3,125 ways to win, set in a misty forest with waterfalls on both sides. NetGame lists the game with high volatility, a maximum win of 6,000x the bet and an RTP of 96.31%; the game comes in several RTP profiles, and SlotCatalog quotes 96.34%. The official hit frequency is 29%.

How the Tumbles Work

The name describes the core mechanic. Every winning combination explodes, the symbols above drop down to fill the gaps, and new ones tumble in from the top – NetGame calls it the Dropdown feature. One spin can therefore pay several times in a row. Because the grid is five symbols high, a single cascade can reshape most of the board, and each new drop is checked for wins across all 3,125 ways again. Wilds get a special role in this chain: according to NetGame, whenever a wild takes part in a win it stays on the grid for the next drop and gains an x2 multiplier.

The Paytable

The game shows its prizes in cash, so the values below are those shown at a $10 stake.

• Leprechaun: $25 for five, $10 for four, $5 for three and $2.50 for two – the only symbol that pays for a pair
• Pipe, beer mug and fiddle: $10 / $2.50 / $1.50
• Blue, red, green and pink gems, and the green triangle: $1.50 / $1.00 / $0.50

Five leprechauns on a way are therefore worth 2.5x the bet. With up to 3,125 ways, though, the real money comes from many ways paying at once rather than from single lines.

Five Fixed Jackpots

A bar across the top of the reels shows five jackpots, and at the $10 stake they read: Grand $50,000 (5,000x), Major $5,000 (500x), Maxi $1,000 (100x), Minor $500 (50x) and Mini $200 (20x). They are fixed multiples of the bet rather than progressive pots, and the Grand alone is worth most of the 6,000x ceiling.

Gold Nuggets and Hold 'n' Link

Gold nugget coins carry cash values. In one of our base-game spins, three nuggets marked 20, 50 and 10 sat on the first reel. NetGame's rules say that eight or more gold nuggets trigger the Hold 'n' Link feature, in which the nuggets drop down and stay held until the round is over – this is where the jackpots come into play. Our screenshots do not show a Hold 'n' Link round, so we cannot report how one played out.

Free Spins With Persisting Wilds

Three or more Tumblin' Dublin scatters award the free spins. Our round opened with the message “You won 8 free spins with persisting wilds with multipliers”. In free spins the wild clovers carry visible multipliers – on the first spin two 4x WILD tiles sat on the grid, and the game announced 21 ways win 400.00, 40 times the stake, for that combination.

By spin seven of eight, the total had reached $477.50 – about 48x the bet – with another 27 ways paying $27 on that spin.

Buying the Bonus

The GET BONUS button in the top-left corner offers a spin that is guaranteed to trigger a bonus. At the $10 stake it cost $1,000, which is 100x the bet. NetGame's official data puts the natural feature rate at 1 in 150 spins, and a big win at 1 in 93, so the buy is a shortcut to a feature that otherwise takes a while to arrive.

What Our Base Game Showed

Outside the features, the wins were small, as you would expect from a high-volatility grid. A wild clover completed a combination worth $9.00, and the spin with the three gold nuggets paid $32.50 in total. The multiplying wilds and the persistence mechanic are what lift the game from there.

The Numbers to Keep in Mind

NetGame publishes more statistics than most studios, and they paint a clear picture. A 29% hit frequency means roughly three spins in ten return something, but with gem wins worth a few cents per way most of those hits are small. The free spins or Hold 'n' Link arrive about once every 150 spins on average, while a big win lands about once every 93. NetGame also caps the maximum exposure of a single game round at €250,000, so at very high stakes the 6,000x multiplier would be limited by that ceiling first.

For a session budget, that means planning for long stretches of small cascades between features. The multiplier wilds are the element that turns a routine tumble into a significant win, so the free spins are where the bulk of the game's value sits.

Graphics and Setting

The grid is framed by two waterfalls in a dark, magical forest, with the leprechaun on the left holding his lantern over a pot overflowing with gold. The gems are rendered as cut stones, the premium symbols are an old pipe, a foaming tankard and a fiddle, and the wilds are four-leaf clovers. It is a polished take on a familiar theme.

Who It Is For

Tumblin' Dublin is for players who like cascading grids with plenty of ways and a real chance of a big hit. The persisting multiplier wilds give the free spins their punch, the five fixed jackpots add a second route to a large win, and the 100x bonus buy is there for those who do not want to wait for the 1-in-150 trigger.
