Nice to see Rishi back. This test is based on variants of Killer Sudoku.
I'm not a big fan of Killer Sudoku, but this test will surely prove to give a good insight into Killer-solving techniques.
A nice, enjoyable test. Some really nice Killer sudokus. I had trouble solving the Toroidal and the Little Killer, but otherwise the solves were good.
My favourite were Greater Than Killer and Twin Killer.
