My site offers puzzles where some of them are a new take on already established classics like Minesweeper, Kakuro, or Masyu. For example, my Minesweeper variant is called Dicesweep, where you need to place dice beside numbers while also matching the row and column rules.
Another interesting one is Kakumino. It's like Kakuro, but you place dominoes instead of numbers.
There are a bunch of them, so there's something for everyone's taste.
