Connect number tiles into chains that equal 12 and cover every square. Adjacent numbers add; one empty square subtracts; two multiply. A chain that works can still leave the rest of the board impossible. Start with practice, then explore three daily puzzles and the archive. Free to play in your browser, no account required.
