The logic puzzle with no words

A row of empty slots, a handful of shapes, and a few rules drawn as pictures. Exactly one order satisfies them all. Find it — then see how much of your solve was reasoning and how much was luck.

App Store How it works

One level, played start to finish: read the pictures, drag the shapes, and watch the marks say which moves were reasoning — green — and which was a guess.

The first level: four shapes, three picture rules, an empty row — Every rule is a picture of the row. Nothing to read, nothing to translate.

A level half solved, with green and yellow marks under the row — Green: the rules forced it. Yellow: right, but you could not have known yet. Red: it breaks a rule.

The result: time, the row of marks, and a share button — The line you share shows the shape of your thinking and gives nothing away.

How it works

Nine kinds of rule, all drawn. This shape sits here. This one comes before that one. These two touch — or never touch. Exactly this many between them. One in the middle of two others. At one end. Before both. At least this far apart.
Every level is proved before you see it. Levels are generated on your device and checked: exactly one answer, and not a single rule that could be taken away. Difficulty is measured, not guessed — it is how many rules you must hold in your head at once.
It watches how you solve, not just whether. 🟩🟩🟨🟩🟥🟩 — deduced, lucky, wrong. Same puzzle, two players, two very different lines.
One a day, a campaign, and endless. The daily is the same for everyone. The campaign's two hundred levels introduce each rule in a level where it is the only new thing. Endless makes as many as you like at the difficulty you choose.
