How to Play Trace
Trace is a daily path puzzle on a walled grid. Draw one unbroken line that enters every single cell exactly once, moving only up, down, left and right, never diagonally and never through a wall. Scattered across the board are numbered waypoints, and the line has to start on 1 and reach each number in ascending order, finishing on the highest. Every board is run through a solver before it ships, so exactly one route satisfies all three rules and you never have to guess. Drag with a finger or a mouse to draw; drag back along the line to rub it out. There is no check button and no fail state - the puzzle simply locks when the grid is full and legal. Trace uses no words at all, so the same board is served to every player in the world and only the interface translates.
How Trace works
Trace is a coverage-path puzzle: one unbroken line that enters every cell of a small walled grid exactly once. Mathematicians call the shape a Hamiltonian path; on the board it just looks like a route that misses nothing and never doubles back.
Three rules run the whole game. Cover: every cell is entered exactly once. Move: steps go up, down, left or right only, never diagonally and never across a wall. Order: the line starts on the cell numbered 1 and reaches each numbered waypoint in ascending order, finishing on the highest.
Those three rules together pin down exactly one answer. Every board served here is run through a solver first, and only boards with a single solution are published - so if you are stuck there is always a cell whose neighbours force the route, and you never need to guess and backtrack blindly.
Input is a drag: press the 1 and pull the line through neighbouring cells. Dragging back along the line rubs it out, so a wrong branch costs seconds rather than a restart. On a keyboard the arrow keys move a focus cursor, Enter extends the line, and Backspace removes the last cell - the whole puzzle is playable without a pointer.
The daily board is the same for every player in the world - Trace is language-agnostic, so only the interface translates. Your solve time and move count go to the global leaderboard, and Trace Unlimited generates fresh grids on demand for practice without touching your streak.
Tips & Strategy
Any cell with only one free neighbour left can never be passed through - only entered and left the same way, which is illegal. Spot them early and the route around them is forced.
If a block of cells connects to the rest of the board through a single gap, the line has to enter and leave through that gap. That is impossible unless a numbered waypoint sits inside, so those shapes rule whole branches out.
Every wall removes a choice, and a board is only published once the walls remove enough choices to leave one route. Treat a dense corner as the easiest part of the puzzle rather than the hardest.
The first and last cells of the route are fixed by the numbers, and their neighbours are usually forced too. Building from both ends meets in the middle faster than drawing forward and hoping.
Dragging back along the line is free. The moment a region looks stranded, back up to the last branch instead of finishing the drawing to see whether it works.
