Hedgehogs
Two hedgehogs in every row, column and flowerbed. No two may touch, they prickle. Easy on Monday, hardest on Sunday, a new garden at midnight. Hints that explain, a two-step Check, practice sets and a free archive going back a year.
More games are on the way: a single-loop puzzle and a knight-move number puzzle, both generated with exactly one solution. Write to andrej@arling.sk if you want to be told when they arrive.
