Daily logic games: 8 free online puzzles

Daily logic games bring a new puzzle every day, solved by reasoning alone, no special knowledge needed. SIWA has eight of them, all free: from classics like sudoku to deduction teasers like Mastermind, from quick to tough.

Play Sudolito

Two families of puzzles

Grid puzzles such as sudoku, Binero, Pixelo or Bouclo are solved by deduction: each filled cell follows from the previous ones. Code games such as Decrypto, Mindo or Ondulo call for another kind of logic: choosing the try that tells you the most.

Where to start?

Sudolito, a 6×6 sudoku, is the ideal way in: sudoku rules on a shorter grid. Then come Binero and Pixelo, followed by Sudoko's 9×9 sudoku, Bouclo and Ondulo for longer challenges.

A break of a few minutes

Allow from two minutes for a Decrypto code to a dozen for a hard 9×9 sudoku. Grids change at midnight and play on a phone or a computer.
