About the archive

About the Umbra archive

A dated puzzle is not a fresh generation. It is the same grid everyone else played that morning, kept exactly as it ran. Nothing is retired once it is printed, so the run only gets longer. Open a day you missed, or work through a stretch of it in order.

Your first solve of a date is the one that counts toward your record, so a second visit to the same day is practice. A new Umbra is printed every day at midnight US Eastern.

Today’s Umbra is open to everyone. Every earlier day asks for a free account, which is also what carries your solve times and your streak from one device to the next. There is no paid tier and no puzzle behind a price.

How the week is shaped

Umbra does not print the same puzzle shape every day. This is the ramp, and the count is how many of each weekday the archive holds.
