About Lucky Penny 2
Lucky Penny 2 is the follow-up to 3 Oaks Gaming's original Irish luck slot, and it pushes the formula further. Built on an anywhere-pays cluster grid, every matching group of symbols on the 5-reel field counts toward a win.
The slot's engine runs on cascades. Winning symbols vanish, new ones fall in, and the chain keeps going as long as matches keep forming. Layer in the Mystery Multiplier coin and a Free Spins round where the multiplier stacks spin after spin.
Aesthetics of the Slot
The Lucky Penny 2 slot runs a classic Celtic palette: deep greens, warm golds, and flashes of jewel color across the symbol set. Premium symbols – horseshoe, beer mug, clay pipe, and lucky coin bag – are drawn with a crafted, a bit cartoonish style.
Cascade Mechanic
The cascade mechanic – also called tumble or avalanche – is the engine behind every win in Lucky Penny 2. When symbols form a winning cluster, they collapse from the grid. Symbols above fall down to fill the empty spaces, and the game checks for new winning groups. The chain continues until no more wins are possible.
Symbols pay anywhere on the field; the number of matching symbols determines the payout. 8–9 of a kind, 10–11, and 12+ each unlock a higher multiplier tier. SCATTER symbols do not join cascades – they stay in place and only trigger their own function.
Mystery Multiplier
The Mystery Multiplier coin can land on the reels during any spin. It sits on the grid through the full cascade series without removing itself. Once the last cascade in the sequence completes, each Mystery Multiplier coin on the board reveals a random value.
The possible values are: 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 25, 30, 50, 100, 250, 500, 1000. All revealed multiplier values on the reels are added together.
Free Spins
Free Spins trigger when 4, 5, or 6 Scatter symbols land anywhere on the reels. The number of Scatters determines how many spins you receive. During the round, the stacking multiplier mechanic replaces the standard Mystery Multiplier behavior.
Free Spins – Base Trigger
Landing 4 Scatters awards 15 Free Spins. Five Scatters awards 20 Free Spins, and six Scatters awards 25 Free Spins. Scatters appear on all five reels, so the maximum entry is achievable on a single spin. Retriggering is possible: landing 3 or more Scatters during the round adds 5 additional spins to the count.
Stacking Multiplier Mechanic
The multiplier stacks spin after spin until the round pays out or the 20,000x ceiling cuts it short. When a Multiplier symbol lands during a spin that produces a win, its value adds to the round's accumulated multiplier total.
A round with multiple Multiplier-heavy spins compounds fast. The final multiplier applied to a winning cascade at the end of a long Free Spins session reflects every coin collected throughout the round.
Buy Bonus
Buy Bonus lets you enter the Free Spins round directly, skipping the base game trigger entirely. Two options are available, each with a different multiplier range and cost:
| Option | Multiplier Range | Cost |
|---|---|---|
| Free Spins | x2 – x1000 | 100× Current Bet |
| Super Free Spins | x10 – x1000 | 500× Current Bet |
Super Free Spins guarantees a higher starting floor for Mystery Multiplier reveals – the x10 minimum replaces the x2 floor of the standard option. The purchase is made at the current bet level, and all Free Spins play out at that same stake.
Slot Paytable
Lucky Penny 2 game uses anywhere pays – every group of matching symbols on the grid counts, regardless of position or column. The number of identical symbols on the field at the same time determines which payout tier applies. Three thresholds exist: 8–9 of a kind, 10–11, and 12+. Paytable values scale with your chosen bet.

The WILD symbol substitutes for all symbols except SCATTER and MULTIPLIER. The SCATTER does not participate in cascades because it remains on the grid and only contributes toward Free Spins trigger counts. During the bonus round, 3+ Scatters add 5 spins to the remaining total.
RTP and Game Variance
The RTP value for Lucky Penny 2 is 95,6%. Volatility is high, meaning wins are less frequent but larger when they arrive.
The 20,000x maximum win is a hard ceiling. When a cascade sequence or multiplier combination reaches this limit, the round ends automatically and the full amount is paid. The path there runs through Free Spins with a high stacked multiplier colliding with a top-end Mystery Multiplier reveal. For comfortable sessions on a high volatility slot, a bankroll of 100–200 bets gives enough runway to reach the bonus round without overexposure.
How to Start Playing the Lucky Penny 2 Slot
How to Win More in Lucky Penny 2
Every cascade adds a coin to the pile. The most direct route to 20,000x starts by entering Super Free Spins via Buy Bonus at 500x bet – this sets the Mystery Multiplier floor at x10 rather than x2, which changes the expected range of every reveal during the round.
Inside the round, each spin that produces a win and lands a Multiplier symbol adds to the cumulative total. The stacked multiplier climbs with every qualifying spin. When a high-value cascade hits late in the round against a large accumulated multiplier, the total can approach or hit the ceiling. The 20,000x limit cuts the round short the instant it's reached.

FAQ
When a winning combination lands, all winning symbols disappear from the grid. New symbols drop from above to fill the gaps, and a fresh win check runs. The cascade continues until no new wins are formed. Symbols pay anywhere on the reels – there are no fixed paylines.
The Mystery Multiplier is a special symbol that lands on the reels during play. After the cascade series ends, each Mystery Multiplier symbol reveals a random value. The possible values are: 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 25, 30, 50, 100, 250, 500, or 1000. All revealed multiplier values on the reels are added together, and the combined total applies to the full cascade win.
In Free Spins, whenever a Multiplier symbol lands during a spin that ends in a win, its value is added to a persistent round multiplier. This accumulated multiplier carries forward – it does not reset between spins. Each additional Multiplier symbol in the round increases the total further, so a long Free Spins session with frequent Multiplier hits can build a very large cumulative value.
Both modes use the same stacking multiplier mechanic. Free Spins (cost: 100x bet) starts with a Mystery Multiplier range of x2–x1000. Super Free Spins (cost: 500x bet) guarantees a higher starting floor of x10–x1000. Super Free Spins gives a better baseline for the multiplier range in exchange for a higher entry cost.
Landing 4 Scatters awards 15 Free Spins, 5 Scatters awards 20, and 6 Scatters awards 25. Scatters can appear on all reels. During the Free Spins round, landing 3 or more Scatters adds 5 extra spins to the remaining count.
The maximum win is 20,000x the bet. When this ceiling is hit, the round ends immediately and the full 20,000x amount is paid out – no further cascades or multiplier accumulation continues. The most realistic path to this limit is a long Free Spins cascade sequence with a high stacked multiplier combined with a top-end Mystery Multiplier reveal.
