National Puzzle Day
Today is National Puzzle Day, so I hope everyone is doing extra puzzles to celebrate. And if you need a puzzle to do, here are a few that I’ve created recently (roughly in increasing order of difficulty):
Domino | Standard sudoku and quadruples rules apply. Digits in circle must appear at least once in surrounding 4 cells. https://f-puzzles.com/?id=y4ao756c
Consecutive Pairs Killer | Standard killer and difference rules apply (no negative constraint). Digits within cages sum to the number in the corner and may not repeat. Cells separated by a white dot differ by 1. https://f-puzzles.com/?id=y3etu4h3
XV Killer | Standard Killer/Little Killer and XV (with negative constraint). All killer totals are XV (15). https://f-puzzles.com/?id=y3xkvfu5
Subway Stops | Normal sudoku rules apply. The 4 ‘roads’ must each contain all the digits 1-9. Subway Stops (cells that share a letter) must contain the same digit. https://f-puzzles.com/?id=yxopf2bb
