MAGNA-TILES Rail Racers Magnetic Building Set

A: Thank you for your question. Our Rail Racer sets are compatible will all of our sets. We would recommend using the standard sized squares as the smaller microMAGS may fit into the rails, the "ramp" would be too narrow to fit the ball.

A: This was confusing for me as well. Looks like the product title has now been updated to 90 pieces, but according to the images for this product, it is still unclear. In the actual product images, there are 2 that show the front and back of the package. The front says 90 pieces included (small in the lower right corner). The back says only 33 pieces: 2 small triangles, 1 larger triangle, 24 squares, 1 rectangle, 1 ball, 4 rails. Both front and back images say Rail Racers so it’s not like this is for a different product. I purchased this for my kids last month and the back of the package we have is different from the product images. Our package says 90 pieces: 4 small equilateral triangles, 4 small right triangles, 4 small isosceles triangles, 2 grated rectangular shapes, 2 medium rectangles, 6 medium equilateral triangles, 10 medium right triangles, 48 medium squares, 2 medium rectangles, 2 balls, 6 rails. TLDR; no clue why the images are different but it is 90 pieces.
