Slant is a binary-determination logic puzzle and like Sudoku was made popular by Japanese puzzle company Nikoli.
The game is played on a rectangular grid, where clues (in the form of circled numbers) appear at some intersections on the grid.
The object is to draw diagonal lines in each (and every) cell (or square) of the grid, such that the number in each circle equals the number of lines extending from that circle. Take care though; the diagonal lines must not form an enclosed loop.
This lite version supports 4 modes of play on iPhone, iPod Touch & iPad. Oh...and the puzzles are auto generated...so no in-app-purchases necessary!
