there are 4 computers on chess.com. But not all of them match the level they say. For example, computer1-easy has a rating of 1206 and once was a 2316. That's not exactly easy. Computer 2-medium, which should be in the 1300s, is in the 1600s. That's more on the hard side. Computer 3-hard is pretty hard, an computer4- impossible is ok.
