These puzzles are mainly for fun but they include a requirement for some knowledge, which can be gleaned from the pages of this site. The crosswords can be adjusted to your liking. When you click on the 3-bar icon in the top right corner of each puzzle, a drop-down menu appears. You can Zoom to make the grid bigger; have a keyboard appear on the screen; remove the picture from the background; reveal the answer if you are stuck and have the clues appear one by one. Good luck!
