Fill the runs. Let every line tell its numbers.
T-3 Zeno Gram is a picture-logic puzzle played worldwide, filled with our green T-3 orb. The numbers beside each row and above each column are its runs of filled squares, in order. Fill the board so every line shows exactly its runs — and watch each clue turn green.

- Exactly one answer, no guessing

A solved 6×6 from the game: every clue met.
Three rules
Each row has up to two numbers on its left, each column up to two numbers above it. Fill squares so that:
Numbers are runs
A number is a run of filled squares side by side. A clue of 3 is one run of three; a 0 means the line has no filled square at all.
In order, with a gap
Two numbers are two runs, read left to right along a row and top to bottom down a column, with at least one empty square between them.
Every line at once
The puzzle is solved when every row and every column shows exactly its runs. A line whose runs are made turns its numbers green.
Playing
Tap a square to fill it with a T-3 orb, tap it again for a × (a square you know is empty), and tap once more to clear it. The × is only your note: you never need it to finish. Clear empties the board. Show mistakes rings a line whose fills can no longer make its clue.
Every puzzle can be solved by thinking
Each puzzle has exactly one answer, and every step to it can be reasoned out — you never have to guess. Stuck? Show hints names the next idea and shows where it applies.
Thinking it through, with pictures
Each example is a real puzzle from the game, before and after one idea. Every example was checked by the T-3 Zeno Gram engine.
Step by step, until every clue is met
An Easy 6×6 from the game, solved one idea at a time.
Three sizes, three levels
4×4
Where every new player starts: small Easy boards that teach the empty line, the full line and the overlap in a minute or two.
6×6
Quick boards at every level — Easy, Medium and Complex. A good place to practise every idea above.
8×8
Bigger boards with longer chains of reasoning: every Medium needs more line-by-line thinking, and every Complex needs a look ahead.
Your time
Pick 15, 30 or 45 minutes. The clock starts with your first move.
Green clues
A line whose runs are made lights its numbers green, so you see your progress at a glance.
