Roblox glossary.

A Blox Fruits upgrade, paid for in fragments, that rewrites a fruit's move set. It is a cost on top of the trade price, which is why a fruit can be strong in the hands of someone who has awakened it and still trade below fruits that need no such investment.

Blox Fruits' in-game currency, earned from quests and defeated enemies and spent at the fruit shop. The shop's other price, for a permanent copy, is denominated in Robux.

A redeemable string a developer publishes on social media or events. Most games have a Twitter / Settings menu where you paste them in.

Subjective measure of how many traders are looking to buy a specific item right now. Drives effective trade value above or below listed value.

An in-game item that can be purchased multiple times (consumables, currency packs, boosts). Sold through the Roblox API at runtime.

Developer Exchange. The Roblox program that lets eligible developers cash Robux out to USD. Has a minimum threshold (currently 30,000 earned Robux) and a fixed exchange rate set by Roblox, $0.0038 per Robux since September 2025.

An item duplicated through an exploit rather than obtained legitimately. Duped copies inflate supply, and the value of the item drops once the duplication becomes known.

Top-tier Blox Fruits classifications. The elemental class — fruits with passive immunity to physical damage while in their element — is labelled Elemental in-game now; Logia is the older name, still what most trading posts say. Mythicals are the highest-rarity tier.

Adopt Me potions that let a pet fly or be ridden. Whether a pet has neither, one, or both is a large part of what it trades for, so pets are usually quoted with those abilities attached.

A one-time purchase tied to a single game. Owning the pass usually unlocks a permanent perk in that game.

Robux held by a Roblox group. Payouts distribute those funds to members in whole Robux, either as one-time amounts or as recurring percentage splits. The 30% marketplace fee was already taken at the sale that filled the balance, so the payout itself moves the whole amount (checked September 18, 2026).

Pet Simulator 99 term for a giant variant of a pet, far rarer than the base form. Major trading currency inside PS99.

A tradeable catalog item available for a fixed time or in a fixed quantity. Trading them has always needed a subscription: Premium historically, Premium or Roblox Plus now.

The 30% cut Roblox takes at the point of sale on things like gamepass and developer product purchases. A 100 Robux gamepass returns 70 Robux to the seller. It is not charged a second time when a group pays those Robux out to a member.

A third player who holds both sides of a trade that cannot be completed in a single in-game action. It is the classic point of failure in a scam, because a middleman the other trader supplies or vouches for is not a neutral party.

Variant trait on a crop or pet that changes its appearance and value. Used in Grow a Garden, PS99, and others.

Adopt Me pet upgrades. Four fully grown copies of the same pet combine into a Neon; four Neons combine into a Mega Neon. Each stage multiplies the trade value of the base pet, which is why a single top-end pet's price cascades through the whole tier.

Giving up more value than you receive in a trade. Often deliberate: traders overpay to land an item that rarely comes up, or to move a hard-to-trade item along, so an overpay is not automatically a loss.

A Blox Fruits copy bought with Robux that stays in your inventory instead of being consumed when used. Permanents trade in their own market, separate from the physical fruits bought with Beli.

Roblox's monthly subscription, closed to new signups on April 30, 2026. Existing members keep their tier, its Robux stipend and marketplace trading, but cancelling is one-way: you cannot resubscribe. New members get Roblox Plus instead ($4.99/month), which discounts eligible Robux-priced purchases by 10% for the first two months and 20% from the third consecutive month, and includes trading, but pays no stipend. Premium's separate 10% bonus on Robux purchases ended May 30, 2026.

A limited whose RAP has been pushed away from its real trading price, usually by a handful of inflated sales between cooperating accounts. A projected item looks expensive on paper and trades for much less.

Two avatar rigs supported in Roblox. R6 has six body parts (classic blocky look), R15 has fifteen and supports more animation.

Recent Average Price. Roblox's own rolling average of a limited's recent resale prices, shown on the item's catalog page. It is a lagging average rather than a live price, and it still moves as items sell. (Corrected September 11, 2026: this entry used to say RAP stopped updating in February 2025. Only Roblox's legacy resale endpoint did; the market and its RAP kept moving.)

Resetting your in-game progress for a permanent boost. Used in Pet Simulator 99 and many simulator-genre Roblox games.

Roblox's in-platform virtual currency. Used for buying items, gamepasses, and developer products. Purchased with real money, earned by developers, or granted as a monthly stipend to members still on a grandfathered Premium subscription. Roblox Plus, the subscription that replaced Premium for new members, pays no stipend.

The numbered copy of a limited: #1 of 1,000, and so on. Low serials carry a collector premium that value lists and RAP do not price, because they are averages over every copy.

Grow a Garden's in-game currency. Earned by selling crops.

A rarer variant of a Pet Simulator 99 pet, visually distinct from the plain form and worth more in a trade.

Pet Simulator 99's tier above Huge: rarer again, and the top of that game's trading pyramid.

An in-platform exchange of items between two players. On the Roblox marketplace, trading Limiteds requires both sides to hold Premium or Roblox Plus. Inside individual games like Adopt Me, trading uses an in-game window.

Community-agreed worth of an in-game item, used to judge whether a trade is fair. Not an official Roblox figure.

User-Generated Content. Avatar items created by approved users instead of Roblox staff.

A community-maintained table of what items are worth in trades, compiled by hand from screenshots of completed trades and reports from traders. There is no central authority behind one, which is why two lists can carry different numbers for the same item in the same week.

How this site labels an item it tracks but will not price. No source we trust gives it a number yet, so the value column stays empty rather than carrying a guess.
