Build A Keyboard Tier List: The Honest Version
No named keycap catalog or stat table exists in any official or community source checked on October 10, 2026, so no factual S/A/B ranking can be written. What follows is the evidence state, the criteria a real ranking must meet, and the measurement method that lets you rank your own keycaps tonight.
Quick answer: what is rankable right now
Rarity is real — the official description tells players to roll and collect rare keycaps, and completed-set pressure shows up in the badge data. Demand is real too: the most-watched videos about this game are rare-keycap hunts. What is missing is the middle layer every tier list needs: named keycaps with comparable effects. Published stat tables do not exist for this game, so a page of S and A tiers would be fiction with formatting. The useful ranking you can build today is personal and measured: how much did your earnings change when you equipped that keycap? The upgrade planner turns that before/after difference into the same payback math you use for workers and upgrades.
Rarity drives the meta
Creator videos (BemmyBlock's rarest-keyboard run, Zekye's best-keycap start) show players optimizing for rarity first. Interest is documented; outcomes are not.
S/A/B placements
Held until a named catalog or community-measured income effects with methods exist. Held means this page carries criteria and a method — not filler tiers.
Criteria
What a useful tier list must compare
- • A named keycap catalog with rarity labels per name
- • An observable income or progression effect per keycap
- • Acquisition source and repeatability (roll-only, code, or box)
- • Early-game versus late-game usefulness, since rates scale
- • Evidence rechecked after game updates (the last two were September 20 and October 10)
For contrast, the badge table on this site is what publishable game data looks like: five names with official award rates and a checked date. Keycaps lack exactly that layer.
Method
The roll-log: rank keycaps yourself
- 1. Read your earnings per second while your setup runs unchanged.
- 2. Equip the candidate keycap — change nothing else for five minutes.
- 3. Read the rate again; the difference is that keycap's effect.
- 4. Enter cost (or the rolls spent) and the gain into the planner for payback.
- 5. Keep the log per keycap; sort by payback. That is your tier list, measured.
Verified data model
What properly sourced game data looks like
Official Roblox badge award rates, checked 2026-10-10 — the standard a keycap table must meet before it replaces this page's evidence status.
| Badge | Official award rate | Reading |
|---|---|---|
| Welcome! | ~100% | Awarded essentially to every player — a join badge. |
| First Roll | ~100% | Essentially universal, matching the core loop: your first keycap roll. |
| 100 Roll | 18.4% | Roughly one in five players reaches 100 rolls — a real early-game checkpoint. |
| Friends | 8.8% | About one in eleven players; the name points at bringing a friend, but Roblox publishes no description. |
| Keyboard Completed! | reported as 0.0% (under 0.05%) | The game's rarest public badge — finishing a full keyboard setup. Treat it as the long-term goal. |
91,798 players have voted the game up as of 2026-10-10, and 18.4% of players hold the 100 Roll badge — the roll loop is the center of gravity. When a source publishes keycap data at this standard, this page will rank them. Until then, the Build A Keyboard wiki documents the verified systems this evidence state rests on, and the Build A Keyboard beginner guide covers the early progression loop the roll log plugs into.

Ranking status history
This section records movement only when comparable evidence appears — it is deliberately short.
October 10, 2026
Placements remain held after the October 10 place update. Still no keycap catalog, stat table, or measured income study across official, tracker, and community surfaces; the award-rate table above was refreshed from the official badge API.
October 3, 2026
Placements held. No keycap catalog, stat table, or measured income study found across official, tracker, and community surfaces.
What would move it
A named catalog (official or community-measured with methods), a code that adds a keycap tier, or a Dumpling Box contents study. Watch the updates page.
FAQ
Tier list questions
What is the best keycap in Build A Keyboard?
No source can answer that honestly yet. The official description confirms rare keycaps exist, but BAKGAME publishes no named catalog, and no community source checked on October 10, 2026 documents per-keycap stats or income effects. Any S/A/B table you find elsewhere is decoration.
Why doesn't this site just publish tiers anyway?
A tier list is a claim about comparable numbers. With zero published stats, every placement would be invented, and an invented tier list is worse than none — it survives for weeks while being wrong. The page shows the evidence state and the method instead.
Can I rank keycaps myself?
Yes, and the roll-log method below does it in an evening: record your rate before equipping a keycap, equip only that change, and record the rate after. Do it per keycap and you have a personal, measured tier list that beats any guessed one.
Do rare keycaps matter at all?
Rare keycaps are the collectible core of the game and the badge data shows completion is the long-term goal (Keyboard Completed! sits under 0.05% award rate). Whether rarity translates into income is exactly the undocumented part worth measuring.
What would unlock a real tier list?
A named keycap catalog with comparable acquisition sources, or community-measured income effects with methods attached. Either one converts this page from evidence status to rankings. The change log below records when that happens.
