How to play

Four Tumblers

A daily safecracking puzzle. Every day brings one vault, the same for everyone. It has four wheels, each set to a number from 0 to 39, and you have eight tries to find all four.

The basics

1. Pick a wheel and turn the dial to set its number. Set all four, then try the handle.
2. Every wheel lights a lamp for how close it sat to its gate: Open (right on it), Close (1 to 3 away), Warm (4 to 8 away) or Cold (farther than that).
3. It never says which way. The dial is a circle, so 39 sits right next to 0. Numbers your readings rule out fade on the dial and get struck off the chart.
4. Open the vault in eight tries or fewer.

One vault a day

A new vault opens every day at midnight Pacific time, the same for everyone. Finishing it keeps your streak going, whether the bolts come back or the night watchman comes round first.

Sharing

Share a grid of your lamps, one row per try, with how many tries it took. It never shows a number.

Practice

Questions

When is there a new vault?

Every day at midnight Pacific time (3 AM Eastern, 8 AM in London). Everyone gets the same vault.

Does a locked day break my streak?

No. Finishing the day keeps your streak going, whether you open the vault or run out of tries. Your stats keep count of how many you opened.

Can I play more than one vault a day?

Today's vault is the daily. For more, play the practice vaults on One Page Toys. Practice never counts toward your streak.

I lost my streak. Can you restore it?

Your streak lives in your browser on your device, so clearing site data or switching browsers starts it again. There is no account to restore it from.
