TUM-003. That is my number, and no card
will ever carry it after me.

My number TUM-003

Every card gets a number when she is born: a world code and a count. Mine is TUM-003. Numbers are never reused — not even when a card is withdrawn. A gap stays a gap.

World code · The three letters say which world I belong to. TUM is Tumble Cards.
Count · The third card of my world. Not the third on a page: the third ever made.
Not a position · When I sit in a stack as 2 of 4, that is where I sit. My number stays mine.

How does this work?

No website and no menu: everything here is a card — one thing, readable at a glance, independent enough to stand on its own.

Cards belong to a world and grow in families; stacks give them order. What you are looking at is one of them.

Reading the card
NumberTop right, permanent. A number is never reused and never moves to another card.
TurnClick or swipe. The front shows, the back explains — a card has no other sides.
MenuThe three lines, top left: back, turn, the index of this world, and the printable worksheet.
DNAThe sequence in the footer. It identifies a card, even away from this screen.
Every card stands on its own. Take one to the workbench and the rest can stay where they are.
