How to join a cube?

One code. One tap. You’re in.

Joining a Cube is designed to be fast and intentional. Every Cube is private by default, and access is controlled through an invitation code so groups stay focused and trusted.

What you need to join

To join a Cube, you’ll need an invitation code from someone already in that Cube. This code connects you directly to the right group and prevents random or unintended access.

If you don’t have a code, you can always go back and create your own Cube or ask a member to invite you.

Entering the invitation code

On the Join Cube screen, you’ll enter the invitation code exactly as provided. Codes are case-sensitive and validated automatically.

Once you tap Join Cube, Cube checks the code in real time to make sure it’s valid and active.

If there’s an issue, you’ll see a clear message explaining what needs attention.

  • The Cube’s name and details
  • The contribution amount
  • The cycle frequency
  • The current cycle status

You’ll also be notified if there’s an upcoming contribution or if a winner has already been selected.

What joining means

By joining a Cube, you’re agreeing to:

  • The contribution amount
  • The cycle schedule
  • The group size and structure

These rules are set when the Cube is created and can’t be changed mid-cycle. This keeps things fair for everyone.

Privacy and control

Only people with the invitation code can join a Cube. Cube doesn’t surface public Cubes or allow open discovery.

This keeps Cubes intentional, predictable, and built around real relationships.

The takeaway

Joining a Cube doesn’t require setup, approvals, or extra steps.

Enter the code.
Join the group.
Follow the schedule.

Cube handles the rest so you can focus on saving together, not managing logistics.
