Loomlock #90, explained
The board from 2026-09-18 — a 6×6 grid of 14 clues — with its finished loop and a walkthrough of how the deduction goes.
The board
This was Loomlock #90, the daily for 2026-09-18: 8 zeros, 3 ones, 1 twos, and 2 threes scattered across 6 rows. Your task was to trace the single closed loop those numbers allow — the cord below is that unique answer, 20 edges long.
The solved loop for Loomlock #90. Each number is satisfied: it counts exactly how many of its four sides the cord runs along.
How the solve unfolds
Every step below follows by pure logic — no guessing, ever. That is the whole promise of Loomlock: because each board is verified solvable by deduction alone, an edge is only ever drawn when it is provable.
- Start at the 0 in row 1, column 3. A zero forbids the loop from touching that cell, so all four of its edges come straight off the board as crosses — no deduction required. The board carries 8 zeros in all, each an instant foothold.
- Two 3s sit stacked one above the other (row 4, column 6 and its neighbour). The edge they share is forced into the loop, and the two outer edges follow — a classic pattern that cracks the middle of the board open before you have touched a single clue elsewhere.
From there the loop rule finishes the job: at each lattice node the cord either passes straight through or turns, but it can never branch, cross itself, or dead-end, and every clue must end up satisfied by exactly one closed loop. Follow those constraints and the answer above is the only place they can all be true at once.
