This product is dated and low resolution, but the games are quite good.
Like a lot of math education games, this appears to be a product from the 1990's repackaged and sold as new. The resolution is low, the graphics weak, and there are no options to set to higher resolution screens. I suppose the fact that the game is listed as compatible with Win 95 and Win 98 should have been a warning sign.
That caveat aside, the games are excellent, have value for speeding math skills, and kept my child's attention for hours. If you buy this expecting an older product, then I would recommend it.
