[Hint] Seven Pieces – 16 January 2023

Last week’s Seven Pieces has proved more difficult than intended. If you are still working on it, check the hint below.

The new puzzle for this week is Six by Six (by Six). In honor of the MIT Mystery Hunt, you get multiple puzzles in one!

These tangram puzzles may have multiple equivalent solutions, but they always have the same piece at the location of the star. (Or they will have one of the two large triangles, which don’t correspond to any letter.) (ERRATA: Apparently there are still two solutions for the first puzzle. Use the one below, or use the new star placement in the updated puzzle. Thanks, Grant Fikes.)
