Build A Keyboard! has one map — your keyboard plot in a shared server — and six documented systems around it. This page walks the loop as the official description and checked trackers define it, and states plainly which expected systems (modes, arenas, events) have not been documented.
The loop reads straight from the official description: roll keycaps and collect rare ones, hire workers to automate the farm, upgrade and expand the keyboard setup, earn cash toward the leaderboards — and the keyboard keeps earning while you are offline. Servers hold up to 8 players each, created June 11, 2026, and sitting at 9.42M visits by the 2026-10-10 check. There is no mode select and no second map in any checked source: the tycoon plot is the map, and the systems below are the whole game.
Source per row; all checked 2026-10-10.
The core action, straight from the official description: roll and collect rare keycaps. Rolls can be paid from the cash your setup generates. The official page confirms rare keycaps exist but publishes no named catalog, rarity ladder, or odds — those stay undocumented across every source checked.
Workers automate the keycap farm so cash keeps flowing without manual rolls. Trackers (Try Hard Guides, Roblox Den, urgametips) consistently describe hiring workers early as the biggest speed-up. Worker names, costs, and rates are not published by any source checked.
Cash buys setup upgrades and plot expansion. The official description lists 'Upgrade and expand your keyboard setup' as one of the four pillars. No upgrade price table is published; compare upgrades by the earnings change you observe.
The official description promises your keyboard earns while you are away — an unusually explicit idle mechanic. No public cap, percentage, or formula exists, so the planner models offline time from values you enter.
Cash flow feeds server leaderboards with up to 8 players per server. Server size is from the official game API; the leaderboard metric (cash, visits, or setup value) is not publicly specified.
The meta layer sits on top of the loop: three milestone codes grant boosts and items, and five official badges mark progression checkpoints. Both are fully documented on their own pages with sources and dates.
Official Roblox Badge API, checked 2026-10-10. Badges have no published descriptions; the readings below interpret the official award rates, not invented requirements.
| Badge | 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. |
Roblox publishes no descriptions or requirements for these badges. Award-rate percentages are the official win-rate statistic and are a strong hint, but this page does not convert a name into an unlock instruction.
Checked 2026-10-10 — listed because tycoon players expect these and will search for them.
No mode select, arenas, or wave modes appear in the description, trackers, or gameplay videos. The single plot is the whole game world.
No event system or rebirth/prestige loop is documented anywhere checked. The fan tracker mentions rebirth only in passing, without mechanics.
Players share servers and leaderboards, but no player-to-player trading or gifting appears in any checked source.
No distinct maps or modes are documented. It is a single-experience tycoon: your keyboard plot in a shared server of up to 8 players, with no mode select, wave structure, or separate arenas in any checked source. If an update adds modes, this page documents them with a source.
Six: keycap rolling, worker automation, upgrades and expansion, offline earnings, server leaderboards, and codes/badges as the meta layer. Each is documented below with its source.
The official description says players earn cash and climb the leaderboards in servers of up to 8. The exact leaderboard metric (cash, rate, or setup value) is not publicly specified.
The five official badges trace the curve: everyone rolls (First Roll ~100%), 18.4% reach 100 rolls, 8.8% earn Friends, and under 0.05% complete a keyboard — the long-term build goal.
Official API snapshot on 2026-10-10: 9.42M visits, 91,798 up-votes (98.1% positive), 39,627 favorites, 8 players per server, genre Simulation/Tycoon.
