MACRODATA REFINEMENT

Severed floor access terminal
01Move your cursor (or finger) slowly across the data. Certain numbers are wrong. Watch for digits that visibly shiver as you draw near, and listen for a low hum that rises. Sound on helps.
02Drag a box around the scary numbers to refine them. They will file themselves into the correct bin below.
03A selection with no scary numbers is rejected. Trust your feelings, not your eyes.
04Fill all five bins to 100% to complete the file. In VERSUS, every refiner receives the same file. The first to complete it is favored by Kier.

What is Macrodata Refinement?

In the TV series Severance, Macrodata Refinement (MDR) is the department at Lumon Industries where severed employees sort numbers that feel scary into five bins, without ever knowing why. This page is a free, unofficial Macrodata Refinement simulator: a faithful browser recreation of that terminal, complete with the trembling digits, the fisheye cursor, the bins, and the Four Tempers.

How do you play the MDR game?

Move your cursor or finger slowly across the grid of numbers. Anomalous digits shiver as you approach and a low hum rises. Drag a selection box around them to refine them into the correct bin. Fill all five bins to 100% and the file is complete. Praise Kier.

Is it free? Do I need to download anything?

Completely free, no download, no account. It runs in any modern browser on desktop or phone. Enter a refiner name only if you want your work recorded on the leaderboard.

Can I play against other people?

Yes. VERSUS mode gives every refiner in a room an identical file: create a room, share the four-letter code, and race up to four players in real time. Wins and completed files earn points on the global leaderboard.

What is the music?

The ♪ MDE button opens the Music Dance Experience, which streams the official remix EP "Music To Refine To: A Remix Companion to Severance" by ODESZA and Theodore Shapiro via Spotify or Apple Music.
