One rope, one loop. Satisfy every T3rminator.
T-3 Slithers is a single-loop logic puzzle played worldwide, roped together our way. Join the dots into one closed loop; a square holding one, two or three T3rminators™ has exactly that many of its four sides on the loop. Draw it right — and watch every square turn green.

A solved 6×6 from the game: one loop, every number met.
Four rules
The board is a grid of dots. Draw lines between neighbouring dots — across or down, never diagonally — so that:
One closed loop
All your lines join into a single loop that ends where it began — no loose ends.
No crossing, no branching
At every dot the loop passes through once or not at all: each dot has two lines or none.
Count the T3rminators
A square with one, two or three T3rminators has exactly that many of its four sides on the loop — never more than three. A square showing 0 has none of its sides on the loop. A square that is right turns green.
Empty squares
A square with no T3rminator can have any number of its sides on the loop.
Playing
Swipe from one dot to the next to lay rope between them — keep swiping along the dots for a longer run. Tap a rope to take it away; tap the gap again to put it back. With a mouse, click the gap between two dots. Show mistakes marks a square with too many lines, a dot with three or four, and a loop that closed too soon.
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.
One loop only
The same T3rminators, two drawings. On the left one loop gives every square its count — solved. On the right two loops do too, but two loops are never an answer.
One loop: solved
Two loops: not an answer
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 Slithers engine.
Step by step, until the loop closes
A Medium 6×6 from the game, solved one idea at a time.
Two sizes, three levels
6×6
Quick boards at every level — Easy, Medium and Complex. A good place to learn every idea above.
9×9
Longer loops and longer chains of reasoning, for when the small board feels easy.
Your time
Pick 15, 30 or 45 minutes. The clock starts with your first move.
Green squares
A square whose sides are exactly right for its T3rminators turns green, so you see your progress at a glance.

Stuck? The answer is there — but a shown puzzle does not count as solved.
