A 1000-piece puzzle typically has 400 edge puzzle pieces. This is because the edge pieces make up the border of the puzzle, and a standard 1000-piece puzzle is usually 20 pieces by 50 pieces. Therefore, the edge of the puzzle consists of 20 pieces on the top and bottom, and 50 pieces on the sides, totaling 140 pieces. Since each edge piece has two edges, the total number of edge puzzle pieces is 140 x 2 = 400. **

Some puzzle companies offer replacement pieces for a small fee or even for free. If that is not an option, you can also try to find a similar piece from another puzzle that fits in the missing spot. **
