Compete

Your times,
next to real people.

Add friends with a short code and compare times. Leaderboards rank smart-cube solves the server has checked, and your division shows where you are on the way up.

Leaderboards

Ranked on your average of 5.

Boards rank your best average of 5, with best single as a second tab. Pick a day, week, month, year or all time, and compare with friends, your country, your age group, your division or the world. Public boards show a rank, a name and a time, nothing else. How leaderboards work.

A board stays closed until 25 players are on it, so a small group is never put on display.

#Solverao5

The world board opens when 25 players have verified times this week. Until then there is nothing to rank, so nothing is shown.

World · this week · average of 5

Divisions

Six divisions, one ladder.

Your division comes from your best average of 12 over checked solves in the last 90 days. You place after 12 checked solves, and until then you are a Learner. Moving up happens as soon as your average earns it. You only drop after 90 days without an average inside your division.

The cut-offs are a first version and may be tuned once there are real solves to tune them on.

Friends

Add a friend with a code.

A code, not a search

Everyone gets an eight-character friend code like K7QM-4TXC. Share the code or its link, and your friend sends a request you can accept or decline. There is no name search.

A board of your own

Friends see each other’s best times and divisions on a friends board, with the same periods as the public boards.

You stay in control

Remove a friend at any time, block anyone, and report a name or a result that looks wrong. Declining a request is silent. How friends work.

Fair play

Checked turn by turn.

A smart cube reports every turn with its timing. Public boards count only smart-cube solves whose turn list the server has replayed from the scramble to solved. How fair play works.

Friends and leaderboards are new. The boards fill in as people sign in and solve, and every number on them comes from real, checked solves.

This browser can’t reach your cube.

cūbrs talks to smart cubes over Web Bluetooth, which lives in Chrome, Edge, and Opera on desktop. Safari and Firefox don’t ship it, and iPhones and iPads can’t run it at all — that’s Apple’s call, not ours.

One email with the link, nothing else. Or open the app anyway if you know your browser supports Web Bluetooth.
