|---|---|
| Volatility | High |
| Layout | 6 reels of 2 to 7 rows, up to 117,649 ways |
| Max win | 28,000x |
Irish luck on a Megaways grid. Four or more scatters give 10 free spins, where the win multiplier starts at 2x and rises by 1 with every rolling win, with no upper limit. That is how the top prize reaches 28,000x.
2. Gaelic Gold (Nolimit City, March 2020)
| RTP | 96.15% |

| Volatility | Medium to medium-high (sources differ) |
| Layout | 3×3, 5 paylines (more in the bonus) |

A small 3×3 grid with a big top prize. A pot of gold in the centre position starts Rainbow Spins with at least 5 free spins, and you first pick coins that add spins, multipliers and extra rainbow paylines. Read our Gaelic Gold review.
3. 9 Pots of Gold (Games Global, March 2020)
| RTP | 96.24% |
|---|---|
| Volatility | Medium |
| Layout | 5×3, 20 paylines |
| Max win | 2,000x |
Pot Pays award a prize for three or more pots of gold anywhere on the reels. Three free spins symbols on reels 2, 3 and 4 spin a wheel that gives 10 to 30 free spins with a 2x or 3x multiplier. A good middle-of-the-road pick. Read our 9 Pots of Gold review.
4. Leprechaun Goes Wild (Play’n GO)
| RTP | 96.2% (a 94.2% version also exists) |
|---|---|
| Volatility | High |
| Layout | 5×4, 20 paylines |
| Max win | 10,000x |
Three scatters on reels 1, 3 and 5 give 7, 9, 11 or 13 free spins, and every wild that lands during the round stays sticky until it ends. The more wilds you collect early, the bigger the round can get.
5. Finn and the Swirly Spin (NetEnt, November 2017)
| RTP | 96.62% |
|---|---|
| Volatility | Low-medium to medium (sources differ) |
| Layout | 5×5 grid, symbols spiral in from the outside |
| Max win | Sources differ: check the info screen |
Wins pay for three or more matching symbols in a row or column, and new symbols swirl in along a spiral. Wins move a key along the spiral, which unlocks one of four free-spin modes, and random features such as Starfall Wilds can land at any time. It has the highest RTP on this list.
6. Irish Pot Luck (NetEnt, August 2020)
| RTP | 96.06% |
|---|---|
| Volatility | Low-medium to medium (sources differ) |
| Layout | 5×3, 20 paylines |
| Max win | 5,000x |
Three clover jackpot symbols on reels 1, 3 and 5 spin a Jackpot Wheel for the Mini, Midi or Mega prize, and rainbow scatters trigger free spins. The lower volatility suits smaller budgets.
7. Rainbow Riches (Barcrest)
| RTP | 95.00% |
|---|---|
| Volatility | Medium to high (sources differ) |
| Layout | 5×3, 20 paylines |
| Max win | 500x |
The classic Irish slot. It has three bonus rounds instead of free spins: Pots of Gold, Road to Riches and Wishing Well. The top prize and RTP are modest, so play it for nostalgia rather than value.
8. Luck O’ The Irish Fortune Spins (Blueprint Gaming)
| RTP | 95.05% in the base game |
|---|---|
| Volatility | High |
| Layout | 10 paylines |
| Max win | 50,000x (one source lists a lower cash figure) |
Part of Blueprint’s long-running Luck O’ The Irish series. Fortune Spins plays four reel sets at once for a higher stake, and mystery symbols can lead to a cash-collect respin round. Its RTP is the lowest here, so check which version your casino runs.
