About Precise Logic

Precise Logic is a small, independent home for daily logic puzzles. Every day there is a fresh Binary grid, a Mini Sudoku and a Word Ladder: quick enough for a coffee break, and satisfying enough to come back tomorrow.

How the puzzles are made

Each puzzle is generated from the date, so everyone in the world gets the same puzzle on the same day. Before a grid is shown, a solver checks that it has exactly one solution, so every grid can be solved by reasoning alone. Word Ladders use a hand-checked list of common, family-friendly words, and every ladder has a route of three to seven steps.
