ORDR

ORDR is a logic puzzle you can play without reading a single word.

A row of empty slots. A handful of shapes. Above them, a few rules —
not sentences, pictures: this shape sits here, this one comes before
that one, these two are never side by side. Exactly one order satisfies
every rule. Drag the shapes into place and find it.

Then ORDR tells you something no other puzzle does: which of your moves
were deduced and which were guesses. Every placement is marked green
when the rules already forced it, yellow when it was right but you could
not yet have known, red when it broke a rule. The line you share shows
the shape of your thinking and gives nothing away.

ONE PUZZLE A DAY
The same puzzle for everyone, every day, with a result you can share.

A CAMPAIGN THAT TEACHES BY SHOWING
Two hundred levels. Every new rule arrives in a level where it is the
only unfamiliar thing, easy enough to solve by looking at it. Nothing is
ever explained, because nothing needs to be.

ENDLESS
Pick a difficulty and play as long as you like. Every level is
generated on your device and proved before it is shown: exactly one
answer, and not one rule that could be taken away.

DIFFICULTY YOU CAN TRUST
A level's difficulty is measured, not guessed: it is how many rules you
have to hold in your head at once. One is read-and-place. Four is a
real think.

NO WORDS, NO ACCOUNT, NO NETWORK
Nine kinds of rule, all drawn. The same game in every language. No
sign-in, no server, nothing collected, nothing to buy.
