Creek ("Kuriku") is played on a rectangular or square grid. Circles with digits from 0 to 4 may be situated on intersections of lines inside the grid. The digit in the circle indicates how many adjacent cells must be blackened(tree). All the white cells(water) must be connected horizontally or vertically.
Creek is a logic puzzle where players fill in cells with black to match the given numbers, while maintaining connectivity of the remaining white cells. It's a puzzle that requires careful deduction and strategic thinking.
