A dinosaur-themed jigsaw/matching puzzle. Drag the pieces into the right spots to complete the picture.
This one is particularly good for people who like relaxed, low-pressure puzzles — there's no timer and no fail condition to stress over.
It also works well for kids since the colors are bright and the mechanics take about 10 seconds to understand.
Tip: if a piece is confusing you, check the preview image — it makes the full layout clear.
