Daily Futoshiki
The rule
Each chevron points at the smaller of the two digits it sits between.
Fill the grid so every row and every column holds 1 to 6 once each.
Between some pairs of touching cells there is a chevron, and it always points at the smaller digit. Most of these grids start with almost no digits at all.
Start by looking for chains. Three cells in a row with chevrons all pointing the same way must read 1, something, something or end in a 6.
Controls
Click a cell and type a digit, or use the pad. Space toggles pencil marks. Arrow keys move. Progress saves in this browser as you go, so you can come back to the same puzzle later today.
Solvable Without Guessing
Every puzzle here was generated and then handed to a solver that is only allowed techniques a person can use. If it could not finish the grid without a guess, the puzzle was thrown away rather than published. That also makes the answer unique, because every step it took was forced.
