That one website that lets you play dozens of logic puzzles with no ads

Why it's the pick

Simon Tatham's Portable Puzzle Collection has 40 logic puzzles, including Mines (Minesweeper), Bridges, Loopy, Pattern (nonograms) and Solo (sudoku), each generating fresh puzzles endlessly in your browser. It's free and open source with no ads or accounts; the pages look dated and the web versions can't save a game in progress.
