About Range & Reason
A free logic grid puzzle every day, easy to hard across the week
Range & Reason is a free website with a new logic grid puzzle every day. Difficulty follows the week: easy on Monday and Tuesday, medium on Wednesday and Thursday, and hard from Friday to Sunday. A new puzzle appears at midnight UTC. You solve by marking pairings on the grid as ruled out or confirmed, and an answer checker tells you how many you have right. It keeps a day streak and a count of puzzles solved, and your marks are saved in your browser so you can come back and finish later. The site also has printable puzzles, a Kakuro solver and combinations chart, a Zebra Puzzle page, and guides to solving logic puzzles and playing Kakuro. It's free with no sign-up, and it's supported by ads.
