It is believed that there is no Sudoku with 16 clues i.e. with a unique solution. It was mathematically proven in 2012 by Gary McGuire and his team that 17 is the minimum number of clues possible for a valid Sudoku puzzle to have a unique solution; puzzles with 16 or fewer clues cannot have only one solution.

has anyone got some pond/oxygen weed

Whether it’s a courgette takeover or a feijoa frenzy, don’t let those garden gems go to waste!
Our suggestion to you: Did you know you can grate and freeze excess courgettes to use in chocolate cake later? It sounds a bit dodgy, but it makes the cake incredibly moist ... and hey, it counts as a serving of veg, right? 🍫

More than 90% of that excess is absorbed by the oceans, which experienced the highest heat content in history last year.
