Roobik $ROOBIKHow many cubes can you solve in 5 minutes?
One clock for everyone. A new round starts every 5 minutes with the same scrambles for all players. Most cubes when it hits 0:00 wins.
How it works
Join any time
Paste your public address and jump into the live round. You play until the shared clock hits 0:00.
Solve, repeat
Each solved cube pops and the next scramble drops in. Everyone in the round gets the same cubes in the same order.
Most cubes wins
The server replays every turn and counts. Ties go to whoever reached that count first. Then the next round starts.

FAQ
How do the rounds work?
Rounds follow the clock: 12:00 to 12:05, 12:05 to 12:10, and so on, all day. Join whenever you like; you play until the round ends. With less than 10 seconds left you wait for the next one.
You can join one round up to 3 times with the same address (each time starts from cube 1). Your best run counts.
How do I turn the cube?
Drag a sticker to turn its layer, use the on-screen buttons, or the keyboard (keys are listed and can be changed under Controls during a run). Keys turn faces as you see them: F is the face pointing at you, U the top, R the right. A prime like R' turns the other way. M turns like L, E like D, S like F.
Drag the background, use the view buttons or the arrow keys to see every side, bottom included. Moving the camera never counts as a move.
What do winners get?
Whatever the prize note in the live panel says. There is no pot and no automatic payout: the dev reviews winning runs and sends prizes by hand from the coin's creator fees. Nothing is guaranteed, not an amount and not a date.
When the dev reports a payout, its transaction shows next to the winner with a Solscan link. That is reported by the dev, not verified by this site.
How do you handle cheating?
Your browser never reports a score. It sends your turns with their timestamps, and the server rebuilds every scramble, replays the turns and counts the cubes itself.
Runs with turns less than 15 ms apart, or that last longer than the time since joining, are rejected. Runs that look odd (very high speed, a robotic rhythm, solver-short solutions) are flagged, and the dev replays winning runs before paying. A careful bot could still look human, so treat the board as provisional.
Do you need my wallet or a signature?
No. Roobik never connects to a wallet, never asks you to sign and never sends a transaction. It only needs a public address. If you paste something that looks like a private key or a seed phrase, the page blocks it and sends nothing.
Use a wallet you control, not an exchange deposit address. A prize sent to a wrong address can't be reversed.
What do you store?
Your public address, your runs (turns and timestamps, so they can be replayed) and a salted hash of your IP address, used only to limit joins. No cookies, no analytics. Your address, settings and key bindings are kept in this browser only.
Can I practice?
Yes. Practice needs no address and no server, with or without a 5:00 clock. Your best timed practice is kept in this browser.
