A NOVOBUILD PUZZLE GAME FOR iPHONE

Fathom app icon — a cyan sonar sweep over concentric rings in dark water

Fathom

Chart what the dark won’t show.

Probe hidden routes, read the signal, and spend your Intel wisely. Every move reveals part of the puzzle. The best path is the one you can prove.

EVERY MOVE WRITES THE MAP

How much is the next answer worth?

The dark is not random. It is information you have not earned yet. Probe an edge for one Intel, spend two on a focused Sonar, or commit five to a wider Deep Pulse.

Probe

1 INTEL

Test one direction. Move through an open route or permanently chart the wall that stopped you.

Sonar

2 INTEL

Send a focused pulse through the nearby dark for a brief tactical glimpse.

Deep Pulse

5 INTEL

Reach farther with a wider reveal. Powerful when you are stuck—expensive when you are not.

There is no timer and no move limit. Fathom rewards observation, memory, and efficient decisions. Learn at your own pace, then return to improve your route.

THREE WAYS INTO THE DARK

A puzzle for the next five minutes—or the next perfect run.

Campaign

Twelve handcrafted missions introduce the rules, then ask you to combine them in smarter ways.

Daily Challenge

A fresh Easy, Medium, and Hard sequence generated for the day. Finish one challenge and move directly into the next.

Free Dive

Endless seeded missions for players who want another map, another route, and another chance to read the dark cleanly.

The signal changes. So does the job.

Echo Hunt

Find the hidden objectives by interpreting what each signal tells you.

Relay Chain

Reach multiple objectives and chart a route through the dark.

Sector Survey

Turn uncertain space into a reliable map.

The map stays still. Your solution gets sharper.

Your Intel score records how efficiently you solved the mission. Grades from S to C make improvement easy to understand, while Daily Challenges and Free Dive keep the next chart unfamiliar.
