Logic Grid

Logic Grid has no timer and does not punish a mistake with a life. You can stop mid-board, close the tab, and come back tomorrow to the same arrangement. These are puzzles whose answer can be proved rather than guessed: number crossing, region cutting, tile rotation, sequence building, and digital versions of the pencil games printed beside the crossword. Because there is no clock, this is the section we reopen most often while assembling the list: a title has to still make sense after the twentieth level instead of repeating the same trick with larger numbers. We also mark the ones that save progress in browser storage, so a half-finished board survives a few days away.
