Caveman Jigsaw

Caveman Jigsaw is a prehistoric picture puzzle with a clock. The images follow an ancient caveman theme, and each one has to be rebuilt by dragging and dropping its pieces into their exact locations before time runs out.

Two modes set the size of the job. Easy mode splits a picture into 24 pieces, and Hard mode doubles that to 48. The jump matters more than the numbers suggest: with twice the pieces, each one carries less of the picture, so you rely more on shapes and edges and less on recognising the scene. Because the timer is part of every puzzle, Hard mode is a test of working speed as well as patience.

That makes this a good jigsaw for players who like a little pressure. It is short enough to replay, and the theme gives it a lighter personality than a plain landscape puzzle. Try Easy first to learn the pictures, then see whether you can beat the clock on 48.

1. Pick Easy with 24 pieces or Hard with 48.
2. Drag a piece to the exact spot it belongs.
3. Keep placing pieces while watching the time.
4. Complete the picture before the timer ends.

Against a clock, the corners and edges come first. They are the fastest pieces to identify, and a finished border makes the middle easier to place.
