How to play Centered or Not

What is Centered or Not?

A daily game for collectors who check centering first. Every card front is a scan of a card in the owner's own collection.

How does a day work?

1. Drag the four guide lines onto the card's inner border.
2. Check the left/right and top/bottom split, then lock it in.
3. Measured cards score by how close you land. Can't measure is always free.

5 rounds a day, the same for every player. There is no clock: take as long as you like. A new day starts at midnight, your local time.

How do points work?

A measured card earns a point for every ratio point your lines miss by less than the typical split for its era, and costs one for every point more, up to 3 either way. Within 1.0 is dead-on, within 2.5 sharp. Can't measure costs nothing. Nothing is scored for speed or for agreeing with other players.

What if the answer isn't in yet?

Your call is saved. When the answer comes in, it is scored and your day's result updates the next time you visit.

How do challenges work?

After your day, tap Challenge to share a link. Your friend plays the same rounds, and your calls stay hidden until they finish.

When can I see past answers?

Two days after a round was played, once its day has passed everywhere, for every card whose answer is known.
