The 6th annual Indie 500 Crossword Tournament Charity Puzzle Pack

Welcome, at long last, to the Indie 500 Science Fair! While these puzzles were originally intended for use at the 2020 Indie 500 Crossword Tournament, we’ve released them in a non-competitive format, because the real prize... is the science we learned along the way! This puzzle pack will raise funds for a wonderful group of nonprofit organizations, detailed below, that were chosen by our organizers and constructors.

In this charity puzzle pack, you’ll get to take a tour of the projects that our budding cruciverbologists have been working hard on. (For the full effect, print these puzzles out on extra-large paper, then paste them onto a tri-fold poster board before solving.) There are eight puzzles of various sizes and difficulties, including a warm-up puzzle and a tiebreaker puzzle. Puzzle 6, “Final,” comes with two sets of clues: one that’s about as tough to make a dent in as diamond, and one that’s a little more malleable. Solutions are also included (though precipitates are not).

To get a copy of the puzzle pack, make a donation of $10 or more to any of the charities listed below, send a copy or screenshot of your receipt to, and we'll email the puzzles within 24 hours.

We are also currently offering all of our past tournament puzzle packs for free. Use the links below to download.
