About
The world was once a single board: 64 squares, each a place and a name. The Dividers shattered it. You are a Geometer; find the measure and seal the board again.
HOW TO PLAY
Every seal carries a number. Enclose it with a rectangle of exactly that many squares. Areas never overlap and each holds one seal. There is no timer in the story: every board gives you a set number of moves, and both a wrong attempt and removing an area cost a move. On the daily board the clock counts down, and every correct area gives seconds back.
SEALS AND CELLS
· A frozen seal only lies flat
· An upright seal only stands tall
· A fire seal needs room
· A king seal leans on the wall
· A shadow seal reveals its value when its neighbour is sealed
· Ember cells give a reward; ice and dark cells cannot be covered
· A spark cell detonates when an adjacent area is sealed
WHAT'S INSIDE
· 6 regions, 64 boards — each with exactly one solution
· A new daily board every day: everyone solves the same seals
· Live leaderboards: daily, weekly, and an all-time star board that never resets
· Hall of Honour: the leaders of yesterday and last week
· 32 badges — for real achievements only

No dice, no luck. Only the measure.
