About

A daily logic grid puzzle, in the style of zebra puzzles, where every clue is a picture instead of a sentence. A 4x4 and a 6x6 puzzle are released each day, the same for everyone. Each puzzle is checked by a solver to be solvable by deduction alone, with clues trimmed to the minimum for its difficulty. Free to play with no signup, and progress is stored in the browser.
