A radioactive farmyard slot built around two escalating ideas: Wilds can spread across the 5x4 grid, while Silver, Gold and Diamond collectors turn a three-respin bonus into a running prize calculation.
Know this game
Collector colours change where a respin award draws its value from. Silver reads the amounts above the feature, while Gold can also draw on money already held on the grid. Diamond creates a further interaction with the existing board, allowing those positions to collect additional top-row values.
Inside the game
The game separates its action into a familiar Wild-led base and a more involved respin feature. Understanding how values move around the grid matters more than memorising every radioactive symbol.
A Silver Wild can add between one and six more Wilds before transforming itself. Gold follows the same spreading pattern, but every added Wild may carry a multiplier as high as 1,000x. The number and placement are random, so a dramatic animation can still produce a modest line result. Watch which new positions actually connect symbols before judging the event by the multiplier label alone.
| Wild | Spread |
|---|---|
| Silver | Adds one to six Wilds before transforming itself |
| Gold | Similar spread; added Wilds may carry multipliers up to 1,000× |
Landing three Scatters awards three initial respins. A collector that arrives becomes a money symbol, locks in place and restores the counter to three. This is the source of the bonus tension: every fresh collector both adds value and buys more opportunities for the grid to develop. The round ends only when the remaining spins reach zero.
Start three respins.
Resolve its value, turn it into a locked money symbol and restore three respins.
End the round and add every remaining money-symbol value for payment.
Seven random money values are displayed above the feature. A Silver collector takes up to six of those values, adds them together and turns into a money symbol carrying the result. It is the easiest collector to read because its calculation has one visible source. Use it as the baseline before comparing what the later colours do.
| Collector | Value source |
|---|---|
| Silver | Up to six of the seven overhead money values |
| Gold | Overhead values plus existing money on the grid |
| Diamond | Current money board first, then those positions gather more overhead values |
Gold starts with the same top-row collection but also takes values already held by money symbols on the grid. Diamond first reads the current money board, then lets those positions collect further values from above. That can create the sharpest escalation because several existing symbols change together. The final award is the sum of every money symbol left when the respins finish.
Whether layered collecting stays clear as values feed each other
Open the paytable before chasing the feature, then watch Silver, Gold and Diamond separately. The bonus is strongest when each step feels readable rather than merely busy.
Use ordinary spins to see whether Silver and Gold Wild appearances make the base game feel active. Gold-created Wilds can carry large multipliers, but they are not guaranteed.
Let the free demo trigger naturally before considering either purchase option. Three starting respins can extend when a collector lands, so judge the rhythm as well as the final total.

04 / The SlotsCollector take
Because held symbols can influence later collections, the board's history matters alongside the remaining counter. Each fresh collector locks as money and restores the attempts, giving the developing grid another opportunity to interact. The eventual result is settled from the money left when the feature ends, not simply from the first attractive top-row value.
Harvest Moon - Grave Profits is more interesting than its deliberately grotesque artwork first suggests. The base game has a simple job: introduce spreading Wilds and put three distinct animal Scatters in view. The bonus then becomes the main event. A Silver collector samples values from the row above the grid, Gold also reaches money symbols already in play, and Diamond can push the whole board into a new round of value building. That hierarchy gives the respins a visible direction instead of repeating one generic collect animation. It also makes the feature busier than a basic hold-and-win, so the demo is valuable for checking whether you can still understand the total when several transformations happen together. The published 10,000x maximum is a ceiling, not a likely session result. This is best approached as a medium-to-fast spectacle for players who enjoy persistent symbols, reset tension and the possibility that one collector changes the value of many positions.
