Bureau of Constants

Different physics. The same desk. Build a universe, file its closure, and grow an office full of instruments, investigations and letters.

Your desk comes with a universe. The lift doesn't work.

At the Bureau of Constants, you build a universe from Quarks upward, file its closure, and take delivery of the next one. Each charter changes the rules: different Laws, different milestones, a different way to put the desks to work.

Keep more than a bigger number. Establish an Archive, Laboratory, Workshop and Observatory. Earn instruments, investigate new ways to run a universe, prepare opening stock, and leave research on the bench while you're away.

The people at the Bureau have their own business, too. Read their letters, write back if you like, and keep the notes left in your drawer. Pell remembers. Orrin has opinions about the tea. The eleventh field on your charter is still blank.

• Fourteen Laws, including paired Laws, with readable charter previews. • Insight upgrades, permanent automation, and later Cosmology and Axioms. • Relics, experiments and opening kits that give the next universe new possibilities. • A separate automated survey board that keeps running through closures. • Correspondence with remembered replies and a story you can read at your own pace. • Full-rate offline progress, with no time cap.

No ads, no account, and no attendance streaks. The work will wait.

Please keep the drawer tidy.

The tutorial and first three rolled universes are free. One permanent Full Game Unlock opens every universe after them and keeps your progress. No subscription. No ads.
