Lucky Penny is an Irish-themed slot from 3 Oaks Gaming, released on August 29, 2024. It has a 6-reel, 5-row grid, Pay Anywhere mechanics, cascading spins and multiplier coins worth from x2 to x1000. The maximum is x20,000 the stake.
The JoyFactory team opened the Lucky Penny demo, took apart the mechanics of the coins and the accumulating multiplier in free spins and checked the stated specs. The main finding concerns the RTP: the provider does not publish it, and this is not a catalog error but the studio’s own position.

Lucky Penny is a modern slot with serious potential and feature-rich mechanics. But it is impossible to assess mathematically: the studio discloses neither the return nor the volatility, and that is the main reason the final score is lower than the game itself could earn.
3 Oaks Gaming
Play for real money
Lucky Penny is available in demo mode with no registration or deposit. The demo reproduces the real game’s mechanics, including the bonus buy menu, so you can try both the regular free spins and Super Free Spins on play credits.
For Lucky Penny, the demo is especially useful. The multiplier coin mechanics are not obvious from the description: the values add up and apply to the total of a cascade sequence, not to an individual win. Seeing it in action is much easier than reading about it.
Keep in mind, though, that the demo shows the mechanics, not the return. With high volatility, a hundred free spins can produce either a run of hits or a complete dry spell, and neither result tells you anything about playing for real money.
Lucky Penny was tested by Oleksandr Petrov, JoyFactory’s casino author.
The test was carried out in demo mode. We launched the game, took apart the Pay Anywhere and cascade mechanics, checked how the multiplier coins and the accumulating multiplier in free spins behave, and opened the bonus buy menu.
We also looked for the official technical specs and did not find them. Neither the game’s own info menu nor 3 Oaks Gaming’s public materials give an RTP figure or a volatility level. Specialist slot catalogs confirm this too. Below we explain what it means for players.
| Pay Anywhere mechanics | Confirmed, from 8 symbols in any position |
|---|---|
| Cascading spins | Confirmed, they work in the base game and in free spins |
| Multiplier coins | Confirmed, values from x2 to x1000 |
| Accumulating multiplier in free spins | Confirmed |
| Gamble feature | Not found, the game does not have one |
| Official RTP | Not found in the game or in the provider's materials |
This is the main problem with Lucky Penny, and it is an unusual one. For most games with a variable return, the provider at least publishes a list of configurations, so players can check which one the operator has set. Here the situation is simpler and worse: 3 Oaks Gaming does not disclose the figure at all.
| RTP in the game's info menu | Missing |
|---|---|
| RTP in 3 Oaks' public materials | Missing |
| Volatility according to the provider | Not stated |
| What review catalogs quote | Mostly 95.64%, some say 96% |
| Confirmation of these figures by the original source | None |
The 95.64% figure travels from site to site and is presented as fact, but it cannot be traced back to the provider. We are not saying it is wrong; we are saying nobody has confirmed it. For a figure that directly affects players’ money, that is a fundamental difference.
What to do in practice. Before playing for real money, open the slot’s info panel at your casino. Most licensed operators are required to disclose the actual value on request, even when it is not shown by default. If you cannot get the figure from a particular casino, that is an argument for choosing another game, not a reason to take a blind risk.
Volatility is not officially stated by the provider either. Judging by the structure of its maths, Lucky Penny is clearly a high-volatility slot: a win requires at least eight identical symbols, and the main potential lies in the multiplier coins and free spins. This means long runs of empty spins, offset by rare big payouts.
There are no traditional paylines. A win is paid when at least eight identical symbols land anywhere on the 6×5 grid; adjacency and direction do not matter.
After every win, cascades kick in: the symbols that formed the combination disappear and new ones drop into their place. If a new combination forms, the process repeats, and so on until a drop with no win. Cascades work the same way in the base game and in free spins.
Lucky Penny does have a wild, which is rare for Pay Anywhere mechanics: most slots of this type do without one. The wild substitutes for regular symbols but not for the scatter or the multiplier coins.
The reels feature familiar Irish symbols: a horseshoe, a tankard, a pipe and a leprechaun’s bag. Gemstones fill the low-paying positions. The leprechaun himself acts as the scatter.
This is the central mechanic of Lucky Penny and the source of its potential.
From time to time, the leprechaun flips a coin onto the reels. Sometimes it returns to his hand; sometimes it lands on the grid and turns a random symbol into a multiplier coin worth from x2 to x1000.
The key detail: the values are added, not multiplied. If several coins are on the screen, their values are summed, and the total multiplier is applied to the overall win once the whole cascade sequence has finished, not to an individual hit.
This leads to the main strategic point: a coin is worth far more when it appears at the end of a long cascade sequence, because it multiplies the accumulated amount rather than a single win. A coin on an empty spin gives you nothing.
In Lucky Penny, the coins work both in the base game and in free spins.
In Lucky Penny, the bonus round is triggered by leprechaun scatter symbols. According to public data, you need four or more scatters, and the number of spins awarded depends on how many land. During the round, extra scatters add more spins.
The main difference in free spins is the accumulating multiplier. Unlike in the base game, the coin values do not reset between spins but are added to an overall counter that stays active until the end of the round. Every new coin makes all subsequent wins more valuable.
It is this mechanic that produces the x20,000 maximum: reaching it takes a long run of spins with regular coins, during which the counter has time to climb to large values.
There is also a separate Super Free Spins mode with a guaranteed starting multiplier, available through the bonus buy menu.
Lucky Penny lets you buy direct entry into the bonus round without waiting for scatters to land naturally. Two options are available: regular free spins and Super Free Spins with a guaranteed minimum multiplier at the start.
The exact price depends on the operator and is shown in the buy menu inside the game. The provider does not publish the stated return of each option, just as it does not publish the base RTP, so it is mathematically impossible to compare which purchase is better value.
The bonus buy feature may be disabled at some casinos. It is worth checking whether the menu is available in demo mode before you deposit.
According to public data, the bet range is roughly €0.20 to €25 per spin. The upper limit matches the stated maximum: x20,000 of €25 gives €500,000.
The exact hryvnia limits are set by the operator, so check them in the game interface itself.
A tip on bet size. With high volatility, what matters more is not the size of the bet but how many spins your bankroll can cover. Lucky Penny is built on rare big payouts, so a short session with large bets will most likely end with nothing, regardless of how generous the slot is over the long run.
3 Oaks Gaming is integrated into the catalogs of licensed Ukrainian casinos. In particular, the studio is explicitly listed among the providers at First Casino, which tops our ranking of operators with a PlayCity license.
| First Casino | Confirmed, September 11, 2026 |

| SuperGra | Confirmed, September 11, 2026 |
| Slots City | Confirmed, September 11, 2026 |
| Gorilla | Confirmed, September 11, 2026 |
Lucky Penny is also listed at casinos without a Ukrainian license. But for this slot in particular, offshore play is a bad deal.
The reason is simple. The provider does not disclose the RTP, so the only source of this information is the operator itself. A licensed Ukrainian casino has a regulator you can turn to with questions. An offshore one has nobody: no PlayCity and no other mechanism that would force it to disclose the game’s actual configuration.
Add the x20,000 maximum, which at a €25 bet means €500,000, and the €5000 monthly payout limits recorded in our section on unlicensed casinos, and you simply will not be able to collect a big win in a single payment.
Offshore operators are rated on a separate scale: the safety ceiling there is about 3.0 out of 10, even with a valid certificate.
The full ranking of licensed operators is on the licensed casinos in Ukraine page.
Powerful mechanics and high potential, but the provider discloses neither the RTP nor the volatility. The game's maths cannot be assessed.
Maths: 4.5. The lowest score in our slot selection, and the reason is not bad numbers but the absence of numbers. The provider publishes neither the return nor the volatility, so the game cannot be assessed mathematically. The figure quoted by catalogs is not confirmed by the original source.
Win potential: 9.5. x20,000 is the highest maximum among the slots we have reviewed. Coins worth up to x1000 with additive values and the accumulating multiplier in free spins make this ceiling more than decorative.
Features: 8.5. Pay Anywhere, cascades, multiplier coins, two free spins modes and a bonus buy. A wild in a slot of this type is a welcome rarity. The score is not higher because there is no gamble feature and the bonus modes are similar to each other.
Interface and usability: 8.0. Bets from €0.20, full HTML5 mobile optimisation and clear controls.
Availability: 9.0. 3 Oaks Gaming is integrated into the catalogs of leading Ukrainian operators with a PlayCity license.
The rating was given on September 11, 2026 under the JoyFactory methodology. You can see who worked on this article on our editorial team page.
There is no official value. 3 Oaks Gaming does not publish the figure either in the game's info menu or in its public materials. Review catalogs mostly quote 95.64%, but this number cannot be traced back to the provider. Ask the support team of your casino for the actual value.
The maximum is x20,000 the stake. At the upper limit of about €25 per spin, that is roughly €500,000. The route to the maximum runs through free spins with the accumulating multiplier and coins worth up to x1000.
From time to time, the leprechaun flips a coin onto the reels. If it lands on the grid, a random symbol becomes a multiplier worth from x2 to x1000. The values of several coins are added together and applied to the total of the whole cascade sequence, not to an individual win.
The provider does not officially state it. Judging by the structure of its maths, the game is high-volatility: a win requires at least eight identical symbols, and the main potential lies in the coins and free spins. In practice, this means long runs of empty spins.
Yes, the game has a bonus buy menu with two options: regular free spins and Super Free Spins with a guaranteed starting multiplier. The price depends on the operator. Since the provider does not publish the return of these options, it is mathematically impossible to compare their value.
In Super Free Spins, the round starts with a guaranteed minimum multiplier, so the counter does not start from zero. This raises the entry price but shortens the path to big payouts.
In the base game, the coin multiplier applies to the result of the current cascade sequence and then resets. In free spins, the values build up in a shared counter that stays active until the end of the round, so every new coin makes all subsequent wins more valuable.
October 9, 2026: scheduled update, content refreshed and data fact-checked.
September 11, 2026: first publication of the review. Oleksandr Petrov tested the slot in demo mode: he took apart the Pay Anywhere and cascade mechanics, confirmed the range of multiplier coin values, checked the accumulating multiplier in free spins and the bonus buy menu, and noted the absence of a gamble feature. We also documented the lack of official RTP and volatility data in 3 Oaks Gaming’s materials and checked the slot’s availability in the catalogs of licensed operators. The next scheduled check is in three months, or earlier if the provider discloses the technical specs.
