Logic puzzle. Fill every cell with a diagonal slash. Each numbered corner tells you how many diagonals must touch it, and the diagonals may never form a closed loop. Solve as many as you can in 150 seconds.
Every cell must hold a single diagonal line — either ╲ (top-left to bottom-right) or ╱ (top-right to bottom-left). Tap a cell to cycle through the options: empty, then ╲, then ╱, then empty again.
The dots sitting on the grid corners are your clues. A numbered dot tells you exactly how many diagonal ends must meet at that corner — a 0 means no diagonal may touch it, a 4 means all four surrounding cells point into it. Corners without a number can have any count.
There is one more rule that makes Slant a real logic puzzle: the diagonals must never form a closed loop. If your lines ever join up into a ring, the loop is highlighted in red so you can break it.
The clue dots turn green when their count is exactly right and red when too many diagonals touch them. The puzzle is solved when every cell is filled, every numbered corner is satisfied, and there are no loops — then a fresh grid appears at once. Solve as many as you can before time runs out.
Start with the 0s and the 4s — they leave no choice. A 0 corner forbids every diagonal from pointing at it, so each of the up-to-four cells around it is forced to the orientation that points away. A 4 does the opposite: all four cells must aim into it. These give you a cluster of free cells with no thinking at all.
Corner and edge clues are powerful because they touch fewer cells. A 1 in the very corner of the board touches only one cell, so it fixes that cell outright. A 2 on an edge touches two cells and a 0 or 4 nearby often forces the rest.
Keep the no-loop rule in mind as you go, not just at the end. If three sides of a small square are already drawn as diagonals forming most of a loop, the fourth cell is forced to the orientation that avoids closing it. Watching for almost-loops prevents dead ends.
Work outward from each solved clue: every diagonal you place changes the counts at both of its corners, which often pushes a neighbouring numbered dot to exactly its target or one short, forcing the next cell. In the timed mode, chase those forced chains and only stop to reason when nothing is forced.
