First steps when you load in
Step
In short
Opening crates and hiring workers sets you up for faster progress.
When you first join, your main job is to open crates so you can collect keycaps and begin building your keyboard. As your keyboard gets stronger, new types of keyboards and crates become available to you.
- Open crates spend your money on crates to get keycaps.
- Check your keycaps look at the rarity of what you received.
- Strengthen your keyboard use the keycaps you have collected to upgrade your keyboard.
- Hire workers hire workers so money keeps coming in while you are away.
- Check for unlocks after upgrading, see whether any new keyboards or crates have become available.

Not every crate gives you the same pool of keycaps. Higher-tier crates offer better rarity odds.
Tips worth knowing
- Earning money faster directly speeds up how quickly you can reach better crates.
- Different crate types have different rarity distributions.

06
Playing in the same room as others
Warn
In short
Rooms hold up to seven players, but everyone's progress and items are completely separate.
Up to seven players can be in the same room at once. Each player's keyboards, keycaps, and money are independent — there is no way to hand items or currency to someone else in the room.
Worth watching out for
You cannot send keycaps or money directly to another player in your room.
Each player's progress is completely independent.
Once a room reaches seven players, new players joining will be placed in a different room.

Common questions
FAQHow many players can be in the same room?
Up to seven players can share one room. If a room is already full, any new player joining will be put into a different room instead.
Do I earn money when I am not playing?
Yes, as long as you have hired workers. They keep generating money while you are offline, and when you return the accumulated amount will be there ready to spend.
Why am I not getting rare keycaps?
Rarity depends on which crate you are opening. Unlocking a higher-tier crate improves your chances.
Can I trade keycaps with someone in my room?
No. Every player's keycaps, keyboards, and money are completely independent. There is no direct trading or sharing between players in the same room.
