An ordinary sudoku, plus drawn lines that read the same from either end. Rows, columns and boxes still hold 1 to 6 exactly once.
About Kayak
Kayak is a free daily palindrome sudoku from Mind Loft on a small 6×6 grid, in six boxes two squares tall and three wide. Every row, column and box holds 1 to 6 exactly once, and every grey line reads the same from either end, so its two end squares match, then the next two in.
It is the quick version of Racecar: the same idea in a few minutes. Every board has exactly one solution you can always reach by logic, with no guessing, and boards get harder through the week, with a harder Sunday Edition.
A new board drops every day at midnight Eastern. No app, no signup, play free in your browser. Want the full-size version? Try Racecar, or Sixes, the plain 6×6.
