NumberBrix - Logic Puzzle

Write 1 onward and link each number to the next across the grid. Every puzzle has one answer, always solvable by pure logic — never by luck. New daily puzzle inside.

Write the numbers in order, one after another. Place 1, then 2, then 3 — each number next to the one before it, up, down, left or right — until a single winding path fills every square. That's NumberBrix.

A few numbers are given. Fill in the rest so 1 to N form one continuous line, and the grid is solved. Simple to learn — quietly absorbing to master.
