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.
