About this site

zrbuilds is eight daily puzzle games: free, with no sign-up and no ads. Every game has a new puzzle at midnight UTC, the same one for everyone, and every past daily is in the Archive. Today keeps your progress and streaks across all of them.

The logic puzzles (Campsite, Killer Sudoku, Skyscrapers, Bridges and Nonogram) are made and checked by a program that solves them the way a person would, so each has exactly one answer and can be finished without guessing. Their hints explain the next step instead of filling it in, and none of them limits your mistakes.

Your progress stays in your own browser; there is no account. Privacy says exactly what is kept.
