Adalogical AEnigmas

From The Guardian‘s Alex Bellos: Try your hand at these logic puzzles inspired by Ada Lovelace and designed by Pavel Curtis, a legend in the puzzle community who has a day job as a software architect at Microsoft. The grids are based on Japanese-style logic puzzles like Sudoku and Kakuro, and use similar deductions. Pavel has been releasing new puzzles every month, and you can find more at his website (opens new window), along with gentle hints (opens new window) for first-time players.
