<u>Grow Plant</u>

Grow Plant instantly skips the remaining growth time of a single crop on the player's plot. It costs .

<u>Grow All</u>

Grow All instantly skips the growth of all crops and fruits on the player's plot at once. It costs .

Harvesting

Harvesting is a core mechanic in the game which lets players pick up crops to sell them. Once a crop is collected, it cannot be undone.

For Multi Harvest Crops, only the fruits can be collected, as the Crop will regenerate fruits.

Inventory

Inventory is a core feature added upon the game's release. The inventory is accessible privilegeless, and is used to store items.

<u>Inventory Mechanics</u>

• Players can search for a particular item in the 'Search' tab.
• The base player inventory can contain up to 325 maximum slots
• The inventory has different segments for specific type items. The segments are for Seeds, Crops, Pets, Gears and All.
• Player can give Crops the favorite status. They are now unsellable. ** Players can sell their Crops and Pets on the Sell Stand.

Price Formula

The sell price of a fruit is determined by the following formula: <math>\text{Total Price} = \lfloor \text{SellValue} \times \text{SizeFactor} \times \text{SizeMultiplier} \times \text{MutationMultiplier} \times \text{DecayPenalty} \times \text{FriendsBonus} \rfloor</math>

Where:

• SellValue = The base sell value of the crop.
• SizeFactor = The contribution of the fruit's size, with diminishing returns applied above a threshold (see [[#Size Factor & Diminishing Returns|below]]).
• SizeMultiplier = A scaling factor (default 1).
• MutationMultiplier = The price multiplier granted by the fruit's mutation (default 1 if no mutation; see Mutations). ** For single-harvest crops, the mutation bonus is reduced: <math>\text{effectiveMut} = 1 + (\text{raw} - 1) \times 0.15</math>
• DecayPenalty = <math>1 - \text{clamp}(\text{decayFraction}, 0, 1) \times 0.8</math>
• FriendsBonus = <math>1 + \text{Friends} \times 0.1</math>, where Friends is the number of friends playing on the same server.
• The result is floored (rounded down) to the nearest integer, with a per-crop minimum floor applied last (e.g. Carrot has a minimum of 4).

<u>Size Factor & Diminishing Returns</u>

The size contribution is based on the fruit's Size raised to an Exponent, but past a "knee" point the gains are reduced so that very large fruit are worth proportionally less:

<math>\text{SizeFactor} = \begin{cases} \text{Size}^{\text{Exponent}} & \text{if Size} \le \text{Knee} \ \text{Knee}^{\text{Exponent}} \times \left(\dfrac{\text{Size}}{\text{Knee}}\right)^{\min(\text{TailExponent},\ \text{Exponent})} & \text{if Size} > \text{Knee} \end{cases}</math>

• Exponent = 2.65 by default; overridden per-crop for Mushroom (1.9) and Bamboo (1.75).
• Knee = 5 by default (the size at which diminishing returns begin).
• TailExponent = 1.5 by default (the reduced exponent applied beyond the knee).
• Diminishing returns are enabled by default. Knee and TailExponent each support optional per-crop multipliers (default 1).

<u>Size Exponent Overrides</u>

Two crops use a different exponent rather than the default 2.65:

• Mushroom: exponent 1.9
• Bamboo: exponent 1.75 These lower exponents mean that very large sizes are less dramatically rewarded for those crops compared to others.

<u>Sell-Time Multipliers</u>

On top of the formula above, a global sell multiplier (default 1) and per-crop sell multipliers are applied when the fruit is actually sold. By default, Mushroom sells for 0.5x its calculated value.

Double or Nothing

Double or Nothing is a selling option offered by [[Sell Stand|Steven]] that replaces the Bargain mechanic. Rather than negotiating a higher price, players gamble their entire fruit inventory for a chance to repeatedly double its total sell value.

Once started, each round comes to one of two outcomes:

• Win: The pot doubles in value.
• Bust: The player's entire wagered inventory is lost. No or items are returned.

After each Win, the player can choose between:

• Sell: Cash out immediately, receiving equal to the current pot. The wagered fruits are consumed.
• Double or Nothing: Risk the current pot on another round to attempt doubling it again.
• Nevermind: Abandon the session, keeping the original, un-wagered inventory.

Bargaining

Bargaining is a feature that allows players to negotiate a higher sell price for their crops with [[Sell Stand|Steven]].

When a player selects Bargain!, Steven asks what they would like to bargain over. Players can choose between two modes:

• Bargain This: Negotiates a higher price for the single crop currently being held. Costs equal to 55% of the crop's current offer price.
• Bargain Inventory: Negotiates higher prices for the entire inventory at once. Costs equal to 55% of the total inventory value. Favorited crops cannot be bargained. If the player has nothing to bargain with, Steven will refuse.

Each time a player asks for more, the game rolls a random outcome:

• Won: Steven raises his offer.
• Legendary: A rare outcome that triggers a significantly higher payout.
• Lost: Steven holds firm at the current price.

This feature has been disabled as of Update 1.

<u>Daily Deal</u>

If a Daily Deal is active, a Daily Deal option also appears during bargaining, offering a flat price equal to 5x the crop's base value (or 5x total inventory value for inventory bargaining). The Daily Deal can be used 1 time every twelve hours.

Auction

The Auction is run by the Auctioneer NPC at the Auction Stand. Lots rotate every 30 minutes and may include Seeds, Crops, Pets, Gears, Crates, Seed Packs, and Eggs.

<u>Pricing</u>

The Auction uses a Dutch auction format: each lot starts at a high price and decreases over time until it either expires or reaches its minimum price. Buying early costs more; waiting risks losing the lot. The current price of a lot is: <math>\text{Current Price} = \max!\left(\text{minPrice},\ \text{startPrice} - \operatorname{round}!\left(\text{startPrice} \times \frac{\text{decrementPercent}}{100}\right) \times \left\lfloor\dfrac{t - \text{rolledAt}}{\text{decrementInterval}}\right\rfloor\right)</math> Where t is the current server time.

Props

Props are decoration objects that can be placed in player's garden.

Cosmetics are mainly used for miscellaneous and creative purposes. They are obtained from the Props Shop. Props can be placed or removed through the "Build" tool.

Shop Restock

The player can purchase Shop Restocks for , making them able to instantly refresh the Shop´s, without waiting for the restock timer. Without , all shops restock every 5 minutes.

Codes

Codes are a feature introduced at the beginning of the game. Found in the Settings menu, players can input codes found on the developer's social medias into the textbox.

<u>Active Codes</u>

• TEAMGREENBEAN ** 3x [[Green Bean|Green Bean Seeds]]

Decay

Crops left unharvested on a player's plot will gradually decay over time. Decayed crops lose 80% of their value. Decayed crops will also change their color. Watering a decayed crop will restore it's value and color as well as restore all fruits connected to the crop.

Time Cycles

The whole day lasts 10 minutes, the day lasting 7 minutes 30 seconds, sunset lasting 30 seconds and night 2 minutes.

Items & Gifting

Players can gift items by either sending mail through the mailbox, dropping items, or standing next to a player and gifting them an item. Plants, Seeds, Gears, and Pets can be dropped or gifted, but props can only be mailed. It’s important to note that rare+ pets can not be gifted or mailed, but can still be dropped. More info on dropping ↳ [[Mechanics#Dropping|Dropping]].

If a player's mailbox is full, the items sent will be returned and the player will be notified.

Stealing

At night, players can steal from other plots. To retrieve a stolen fruit, the victim can hit the player with a Shovel. Stealing is free. More info found at Stealing.

Plot Expansion

Players can expand their plot 5 times, each adding two new fields to plant on. Each expansion rises in price. This also increases the limit of the seeds you can plant. {| class="fandom-table mw-collapsible mw-uncollapsed" ! Expansion

Fence Skins

Fence Skins allow the player to customize their garden's fences. They can be accessed through the garden sign in front of the player's garden. They are purely for cosmetic purposes and don't give the player any boosts.

Fence Skins can be obtained through the Fence Crate.

Dropping

Players can drop items by pressing backspace on their keyboard, or a button on mobile. Other players can then pick up the dropped item. Following items can be dropped:

• Seeds
• Gears
• Pets
• Crops
• Seed Packs
• Crates

Mailbox

Players can gift other players using the mailbox. Players can gift Seeds, Gears, Pets and Props. The player can also add an optional note. Mailing is free.
