Harvest Moon – Grave Profits Slot Review
Written by: Filip Gromovic Reviewed by: Nashon Khamala

Harvest Moon – Grave Profits is a Pragmatic Play release built on a 5×4 grid with 15 fixed paylines and a default RTP of 96.50%. The slot replaces the usual free spins round with a Collect Respins feature, where three tiers of collect symbols – Silver, Gold, and Diamond – gather money values from a prize row above the grid.
Medium volatility (rated 3 out of 5) keeps the base game active, with a 17.64% hit frequency in the main mode. The two wild types in the base game carry more weight than standard substitutions: Gold Wilds attach multipliers up to 1,000× per wild position. Bets range from $0.15 to $240, and the max win potential reaches 10,000× your stake.
Theme & Visual Style: Alien Conspiracy Meets Organ Trade
Pragmatic Play drops the studio’s usual fruit-and-gold palette for something far darker here. Harvest Moon – Grave Profits is set in a retro-futuristic world where masked grave robbers harvest organs and sell them to suit-wearing lizard aliens. A UFO hovers above a graveyard in the background, and the colour scheme leans into neon purples and toxic greens.
The tone sits somewhere between conspiracy satire and body-horror, closer to Pragmatic Play’s Hell Butcher than anything in the Sweet Bonanza line. Reel symbols are body parts – brains, hearts, lungs, kidneys, eyeballs, livers, teeth, ears, fingers, and blood vials – each rendered in a clinical, specimen-jar style. There are no card royals.
Visually, the grid stays readable despite the dark backdrop. Symbol outlines are distinct enough to track during wild-heavy spins, and the prize row above the reels is colour-coded to separate collect values from standard positions. Players who prefer lighter themes will find this slot unsettling, but the art direction is consistent and clearly intentional.
Bonus Features in Harvest Moon – Grave Profits
The feature set in this Pragmatic Play title centres on two systems: a random wild mechanic in the base game and a Collect Respins round as the main bonus. There are no traditional free spins, no gamble option, and no cascading reels. Each feature works differently depending on whether it involves Silver, Gold, or Diamond symbols.
Random Wild Feature: Silver and Gold Wilds
The base game uses three wild types. Standard Wilds substitute for all symbols except the scatter. Silver Wilds do the same, but before acting as a wild, they place 1 to 6 additional wilds in random grid positions. Gold Wilds follow the same spread mechanic – 1 to 6 extra wilds – but each added wild can carry a multiplier ranging from 2× up to 1,000×.
The practical difference is significant. A Silver Wild turn may produce a multi-payline hit from scattered wilds across the grid. A Gold Wild turn can do the same but with each participating wild multiplying the line win it contributes to. With 15 paylines and up to 7 wilds on a 5×4 grid, the base game has enough ceiling to produce meaningful wins before the bonus ever triggers.
Collect Respins: The Core Bonus Round
Three scatter symbols on reels 1, 3, and 5 trigger the Collect Respins feature. The round begins with 3 respins and a prize row of 7 random money values displayed above the grid. Every time a collect symbol lands, the respin counter resets to 3, and that symbol transforms into a money symbol that stays on the grid until the feature ends.
Three collect tiers exist, each with different collection behaviour:
- Silver Collect – takes up to 6 values from the 7-position prize row, sums them, and transforms into a money symbol carrying that total.
- Gold Collect – works like Silver, but also adds the values of all money symbols already sitting on the grid to its sum.
- Diamond Collect – first takes the value of every money symbol currently on the grid, then each of those money symbols also collects up to 6 values from the prize row, creating new totals across the entire grid.
When no respins remain, the round pays out the combined value of all money symbols on the grid. The escalation from Silver to Diamond means late-round Diamond Collects, when the grid already holds several money symbols, produce the largest results. This tiered system is the primary path to the 10,000× max win.
Ante Bet and Bonus Buy Options
The Ante Bet doubles the cost of each spin (up to $480 max bet) and increases the probability of triggering Collect Respins. It does not change the RTP. For players who want to skip the base game entirely, two bonus buy tiers are available: 120× the bet for a standard entry and 400× for an enhanced version with better starting conditions.
At $0.15 minimum bet, the 120× buy costs $18, while the 400× buy costs $60. At higher stakes, these costs scale accordingly. Both buy options increase session risk substantially compared to natural triggers, which land approximately once every 213 spins.
Symbols & Payouts
All ten regular pay symbols in Harvest Moon – Grave Profits are body parts. Lower-value symbols include blood vials, fingers, ears, teeth, and eyeballs. Higher-value symbols are kidneys, livers, lungs, hearts, and brains. A five-of-a-kind combination on a payline pays between 1× and 20× the total bet, depending on the symbol.
The scatter (appearing on reels 1, 3, and 5 only) pays 1× the bet when three land, in addition to triggering the Collect Respins feature. Wild symbols substitute for all regular pay symbols but not the scatter. During the respin round, money symbols and collect symbols replace the standard paytable entirely.
RTP & Volatility of Harvest Moon – Grave Profits
The default RTP is 96.50%, which sits above the common 96% industry reference point. However, Pragmatic Play licenses this slot at three RTP tiers: 96.50%, 95.57%, and 94.53%. The casino operator chooses which version to run, so players should check the in-game rules or paytable to confirm the active setting.
Volatility is rated medium (3 out of 5). Combined with the 17.64% hit frequency, this means roughly 1 in 6 spins produces a payout in the base game. The bonus round triggers about once every 213 spins on default settings (more often with Ante Bet active). The 10,000× max win has an estimated probability of approximately 1 in 7.6 million spins.
| Metric | Value |
| Default RTP | 96.50% |
| RTP Range | 94.53% – 96.50% |
| Volatility | Medium (3/5) |
| Hit Frequency | 17.64% |
| Bonus Frequency | ~1 in 213 spins |
| Max Win | 10,000× bet |
| Max Win Odds | ~1 in 7,600,000 |
Compared to high-volatility Pragmatic Play titles like Gates of Olympus (5/5 volatility, 5,000× max win) or Sweet Bonanza (high volatility, 21,100× max win), this slot offers a flatter variance curve. Sessions are less likely to produce extreme droughts, but the max win ceiling is also lower.

Play Harvest Moon – Grave Profits for Free
The demo version of Harvest Moon – Grave Profits uses virtual credits and runs the same math model as the real-money game. All features – Silver/Gold Wilds, Collect Respins, Ante Bet, and both bonus buy tiers – are accessible in free play mode. Demo availability depends on the casino and your region.
Testing the slot in demo mode is useful for understanding how the three collect symbol tiers interact during the respin round. The difference between Silver and Diamond Collects is not obvious from reading the rules alone, and seeing a few bonus rounds play out makes the value escalation clearer. Players new to collect-style respins will benefit from a test session before committing real stakes.
FAQ about Harvest Moon – Grave Profits
The default RTP is 96.50%. Pragmatic Play also offers lower settings at 95.57% and 94.53%, chosen by the casino operator. Check the in-game rules to confirm which version you are playing.
The slot has medium volatility, rated 3 out of 5 by Pragmatic Play. Base game hit frequency is 17.64%, meaning roughly 1 in 6 spins produces a win.
The max win is 10,000× your total bet. Reaching it typically requires multiple high-value collect symbols, especially Diamond Collects, during the Collect Respins round.
No. The slot uses a Collect Respins mechanic instead of traditional free spins. Three scatters on reels 1, 3, and 5 trigger the respin round, which starts with 3 respins. Each collect symbol landing resets the counter back to 3.
Silver Wilds add 1–6 extra wilds to random positions before becoming a wild themselves. Gold Wilds do the same, but each added wild can carry a multiplier up to 1,000×.
Silver Collect takes up to 6 values from the prize row above the grid. Gold Collect does the same but also adds the values of money symbols already on the grid. Diamond Collect takes all current money symbol values, then each money symbol also collects from the prize row to create new totals.
Yes. Two tiers are available: 120× the bet for a standard Collect Respins entry and 400× the bet for an enhanced version. An Ante Bet option at 2× the normal cost is also available to increase bonus trigger frequency during regular play.
Bets start at $0.15 and go up to $240 per spin. With the Ante Bet active, the maximum increases to $480.

Harvest Moon – Grave Profits uses a 5×4 grid (5 reels, 4 rows) with 15 fixed paylines. Wins form left to right across active paylines.
Conclusion: Who Will Enjoy Harvest Moon – Grave Profits
Harvest Moon – Grave Profits fits players who prefer collect-and-hold respin mechanics over standard free spin rounds. The three-tier collect system (Silver, Gold, Diamond) gives the bonus round a progression structure that rewards longer feature runs, and the Gold Wild multipliers up to 1,000× keep the base game from feeling flat between bonuses.
Medium volatility and a 17.64% hit rate make this a better fit for extended sessions than high-variance Pragmatic Play titles. The 10,000× cap is lower than many current releases from the same studio, so players chasing larger max win ceilings may find the upside limited. The dark organ-harvesting theme also narrows the audience – this is not a casual or lighthearted slot.
Try the demo version first to see how the collect tiers interact during respins. If the mechanic clicks, check the in-game paytable at your chosen casino to confirm the RTP is set to 96.50% before playing with real money.
