Practice · vault No. 1

Four Tumblers

The lock has four wheels, one number each, 0 to 39. Pick a wheel, turn the dial to set it, then try the handle. Every wheel reports how close it sat to its gate. Open the vault in 8 tries.

Open right on it
Close 1 to 3 away
Warm 4 to 8 away

It never says which way, and 39 sits next to 0. This is the practice edition of Four Tumblers, a daily game: play here as much as you like, and it never counts. Today's vault, the same for everyone, plus your streak, lives at fourtumblers.com/daily. New here? Meet Four Tumblers.

How to crack it

Read the lamps

Pick a wheel (tap its window), turn the dial to set it, then try the handle. 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
Cold farther

It never says which way, and the dial is a circle, so 39 sits next to 0. Numbers your readings rule out fade on the dial and get struck off the contact chart; tap a square on the chart to jump a wheel there.
