BrainBashers Daily Puzzle

BrainBashers is a puzzle site made and run by Kevin Stone, known for its logic grids, sudoku variants and optical illusions. Its Daily Puzzle page shows one brain teaser each day, headed with the date.

The teasers vary: some are arithmetic word problems (a contest where the scores add up to a total and each player relates to the next), some are riddles, and some are short logic puzzles. There is no grid to fill in and no timer. You read the problem, work it out, and then use the buttons under it: a hint if you are stuck, the workings to see the method, and the answer to check yourself.

All of the site's daily items change at midnight GMT, and there is a time zone setting next to that notice. A weekly puzzle and many daily logic grids sit on the same site. It suits anyone who likes a pencil-and-paper puzzle with a coffee.
