Bitsy is a true binary puzzle: each cell must contain 0 or 1 when using the default 'digits' skin. bitsy now provides 8 additional skins using graphic symbols rather than 0 and 1. the author feels that the 'flat' and 'leftright' skins are most challenging! the rules are simple: - series of three or more 0 or 1 cells in a row or column are forbidden. - the nr of 1's in a row or column must be equal to the number of 0's (or one more for odd sized grids). - identical rows or columns are forbidden. the initial green values can not be modified. your task is to fill the blank cells. tap to change them into a yellow 0 or 1, or to clear them. zooming in may help to select a cell. the background of the two last changed cells is gray and brown. you can ask bitsy to check your answers: wrong values will be colored red. you can choose between - nine skins, - two difficulty levels, and - five grid sizes starting at 8x8 up to 12x12. it takes 1 minute to start playing, but it'll give you hours and hours of puzzle fun! some people use the name 'binero' to refer to this binary puzzle.
