Keycaps
OfficialThe collectible core. Rarity tiers exist ('roll and collect rare keycaps'), and your placed keycaps shape the setup you show off and upgrade.
Build A Keyboard Items & Rewards
Build A Keyboard! keeps its item list short: keycaps you roll and place, cash that buys everything, and three code-granted extras — XP, a five-minute 2x Money boost, and the Dumpling Box. Each row below names its source and the box's unknown contents are stated as unknown, not guessed.
Quick answer: the full documented item list
Five item types cover everything the sources document. Keycaps and cash drive the whole game loop; the other three arrive via codes. The Dumpling Box is the interesting one: it is the only reward container in the game's documented economy, its contents are unpublished, and its very name is reported differently by different trackers. If an update adds a new currency, box, or boost, this page rechecks and the table below grows a row with its source.

The Dumpling Box question
Five trackers word the DUMPLINGCRATE reward as a Dumpling Box; Roblox Den words it as 2 Dumpling Crates. Both wordings agree a container is granted; neither documents its contents or rates. Treat opening one as a reveal moment, not a planned investment — and if you open one, what you saw is more than any public source currently records.

Reward facts no source publishes
Box contents and odds
No loot table for the Dumpling Box exists in any checked source. Any site listing one is guessing.
Per-keycap effects
Rarity labels are official; the income value of any specific keycap is not published. Measure the before/after rate change.
XP curve
THANK5K grants 500 XP, but no source documents level thresholds or what each level unlocks.
FAQ
Items & rewards questions
What items exist in Build A Keyboard?
Five documented types: keycaps (the rolled collectible core), cash (the main currency), XP (from the THANK5K code), the 2x Money boost (from ILOVEKEYCAPS), and the Dumpling Box container (from DUMPLINGCRATE). All are checked 2026-10-10 with sources on each row below.
What is inside the Dumpling Box?
Not publicly documented. Trackers describe Dumpling Crates as keycap drops, but no source lists contents or drop rates, and the reward wording itself differs: most trackers say one Dumpling Box, Roblox Den says two Dumpling Crates.
How do I get the code rewards?
Redeem the three strings in game: click the gear/Settings icon in the top-left, scroll to the Enter Code box, paste the code, and press Redeem. Each works once per account.
Do keycaps affect earnings?
Rarity is official and placing better keycaps is the game's core fantasy, but no per-keycap income effect is published anywhere. Measure your earnings before and after equipping one — the planner turns that difference into payback.
Is cash the only currency?
For buying things, yes — cash pays for rolls, workers, upgrades, and expansion. XP levels you up, and boosts and boxes are consumables rather than currencies.
