A world hides in 64 squares. And you — which piece are you?
A calm logic puzzle played on an 8×8 board. Draw as many squares as each seal’s number, place the areas without letting them overlap, seal the board. Every board you seal sets one square of a broken world back in place.

The world was once a single Board. Sixty-four squares. Each square a place, each place a name.
Those who kept the measure were called Geometers.
Then the Dividers came. They broke the Board. Each piece became a region and forgot its own measure.
We, the Archivists, only kept the record. No one pressed a seal.
Every region is a piece of the Board. Each lost its measure in a different way.
Every beginning comes with a question.
Everything is as it first was. Plain seals, open squares. Under the ice, a corner of the old Board shows.
A burnt edge on the path. The embers are still warm.
Losses teach balance.
It wasn’t fire that burnt the forest; it was the hand that drew the border wrong. The ember cells have not gone out.
A ring of hearthstones; one stone bears the Geometer’s mark. Heading north, a single row of footprints, dead straight.
Silent truths.
First the measures froze, then the hands that held them. The king froze his own squares to protect the rest of the Board.
A throne leaning against the wall. Beneath it, a tablet of confession: “We were the ones who forgot the measure.”
The secret of reflections.
The city didn’t sink into darkness; it forgot what belonged to whom. Everyone hid their own measure.
A shadow sits on the throne. The veil has not yet lifted.
Forgotten knowledge.
Every record is a board, every board a confession. On the last shelf, a blank tablet left for you.
Archivist Nun’s note: “Keeping the record is not enough. Someone must press the seal.”
Not yet awake.
The Board’s first square broke here. The first of the Dividers sat here. Every square sealed here pulls the rest of the world back into place.
No record. You will write this page.
Some squares hold a number in a circle. Every seal wants a rectangle of exactly that many squares. A seal marked 6 takes an area of 1×6, 6×1, 2×3 or 3×2.
Areas never overlap; each area holds only one seal. When every area is drawn and the board is covered, the board is sealed.
Press one corner, drag to the opposite corner, release. If the rule holds, the area lights green and settles into place. If not, the drawing quietly dissolves; only an amber warning shows. Tap a sealed area and it lifts.
Story boards have no clock; think as long as you like. But every placement, every rejected attempt and every removal spends one move. The real danger is silent: an area that obeys the rule but takes the room of other seals gives no error. It locks the board.
Study the board. Press one corner, drag to the opposite corner.
Every square you seal earns points; each move left in hand is added too. The result is shown in ◆ out of five. Five stars ask for a near-flawless game.
Shows one edge of an area first, then the whole area on the second press. You earn one hint each time you enter a board; every use costs points.
The same board for everyone, every day. Three attempts, one ranking. Take your place among Today’s Best.
The seal is the word of the measure. Special seals constrain the shape of the area; special cells constrain the board itself.
Wants a rectangle of as many squares as its number.
Its area can only be a single horizontal row. It does not bend.
Its area can only be a single vertical column.“Some seals lie down, others stand and wait.”
Won’t fit a narrow place. Its area must be at least 2 rows and 2 columns; never a strip.
Its area must lean on at least one edge of the board.
Its value is hidden. It reveals when a neighbouring area is sealed or a hint is taken.
It keeps. Can’t be covered; no area may pass over it.
Sealed fire. The area that covers it earns extra points.
The trace of the breaking, hidden by the Dividers. An area touching its edge must be sealed first to burst it.
It will never light up. Can’t be covered, and it stops a shadow seal from being revealed from that side.





Your country's flag appears next to your name in the rankings. You can pick one of these twenty-one countries in the game.
A logic puzzle of the shikaku kind. On an 8×8 board you enclose every seal with a rectangle of exactly that many squares. No dice, no luck; only the measure.

Six languages: Turkish, English, German, Spanish, Portuguese and French.
Every day the same board opens for everyone. You have three attempts, and the results gather in a single daily ranking.
This record reveals the end of the story. If you would rather play first, do not break the seal.
The Dividers did not come from outside. They were the Geometers themselves, who hid the measure instead of sharing it.
We always knew. We kept the record but never spoke, because we feared losing it.
Fear, too, is a divider.
In the end the Dividers are not defeated. They remember.
“The measure has returned. Names are next.”
