Hebi

Game Rules: Hebi

Build snakes from 1 to 5 in order. Black arrows show the first visible digit, and a snake's head cannot face another snake along an open line.

Place snakes made of the digits 1–5 connected in order through neighboring cells. Different snakes cannot share a side; diagonal contact is allowed. A head looks from 2 through 1: no other snake may lie in that direction before a black cell or the board edge. A black arrow shows the nearest visible snake digit; 0 means no snake before the next black cell or edge. Plain black cells also block sight. Other white cells stay empty. Tap cycles blank → 1 → 2 → 3 → 4 → 5 → X → blank; hold cycles backward, and drag paints that state. You can also tap a cell and use the number keys, X or Clear. X is an optional empty mark. With a mouse, right-click instead of holding.
