About
Verified every name below appears in the shipped dataset and is daily-eligible. 1,847 characters, well under the 4,000 limit.
Two actors. One chain of films. How short can you make it?
CoStar gives you a new pair of performers every day. Link them by
stepping through films they actually appeared in: pick a movie, pick
a co-star from its cast, and repeat until you reach the target.
Fewest films wins.
Everyone gets the same pair on the same day, so you can compare with
friends and argue about who took the smarter route.
A DAILY PUZZLE THAT TAKES FIVE MINUTES
Today's pair, one shot, one score. Build a streak and watch your
solve distribution fill in.
BROWSE, DON'T GUESS
Tap through a performer's real filmography and pick the connection
you spot. You don't need to recall co-stars from memory, which means
you can actually finish the thing.
HARD MODE, IF YOU WANT IT
Hard mode hides the filmography and the target score. Search the
whole library by name and work it out cold. Your difficulty is
recorded with your result, because a challenge nobody can see isn't
worth much.
STUCK? SEE HOW CLOSE YOU WERE
Ask for the answer and CoStar finishes the chain from wherever you
stopped, then tells you whether your own route was still on par. You
keep your streak. You just don't get a perfect solve.
MAKE YOUR OWN CHALLENGE
Pick any two people in the library and send the pair to someone.
Custom challenges draw from the full roster, so you can be as unfair
as you like.
EXPLORE 4,000 FILMS
Wander the whole library. Every performer, their credits, and
everyone they've worked with, each one a tap away. Tom Hanks, Meryl
Streep, Sigourney Weaver, Samuel L. Jackson, Whoopi Goldberg, Keanu
Reeves and thousands more.
FOURTEEN THEMES
Eleven dark, three light. Change it whenever you like.
NO ACCOUNTS, NO ADS, NO TRACKING
No sign-in, no analytics, nothing collected. Your streak lives on
your device. CoStar works offline; it only reaches out about once a
week to refresh the film list.
Free, with an optional tip if you enjoy it.
---
The film list is curated rather than exhaustive. A complete credits
database links almost anyone in two steps through documentaries and
talk shows, which would make every puzzle identical. CoStar sticks to
well-known theatrical features so the connections are ones you have a
fair chance of knowing.
