Seven new prompts every day. Name the answer nobody else thinks of, and watch your krill sink past the Titanic. Then challenge a friend to a duel.
Name the answer nobody else will.
Fathom is a daily trivia game where the obvious answer gets you nowhere. Every day you get seven prompts like "Name something that has a tail" or "Name a famous shipwreck." You have 25 seconds for each. The rarer your answer, the deeper your krill sinks.
Say "Dog" and you barely get wet. Say "Ponytail" and you drop into the twilight zone. Find the one answer almost nobody thinks of and you hit the gem line: One in a Million.
HOW IT WORKS
• 7 prompts a day, the same for every player
• 25 seconds to type one answer per prompt
• Every valid answer has a tier: Plankton, Too Clever, Schooler, Rare, Deep Cut or One in a Million
• Rarer tiers score more points and sink you deeper
• Pass real ocean landmarks on the way down, from the deepest scuba dive to the Titanic and the trench floor
SEE HOW DEEP YOU WENT
• Your depth, your tier chain and how you compare with other players
• The full catch for every prompt: each accepted answer and how many people picked it
• A dive log, milestones and a shareable result card
DUEL YOUR FRIENDS
• Challenge a friend to a head-to-head dive of seven random prompts
• Watch two krill race to the bottom, round by round
• Join with a code, keep a friends list and track your head-to-head record
• Check today's leaderboard to see who dove deepest
DIVE EVERY DAY
• A fresh dive every day at midnight
• Build a streak and keep your logbook of every dive
• Missed a day? Replay it from the archive
