description Str8ts Overview
Str8ts is a logic-based number puzzle invented by Jeff Widderich and popularized by fellow puzzle designer Andrew Stuart. Solvers are presented with a grid containing both white and black cells, where the black cells act as blockers similar to those in a crossword puzzle. The objective is to fill the white cells with digits from 1 to 9 so that no digit repeats in any row or column. Additionally, contiguous white cells within a row or column must form a "straight," meaning they must contain a set of consecutive numbers arranged in any order.
