I’m an electrical engineer living in Los Angeles, CA.
You’re confusing PEGI (the European games rating body) with ESRB (the American equivalent).
PEGI has ratings 3, 7, 12, 16, and 18, and it gave Balatro the highest rating of 18.
ESRB has ratings E, E10+, T, M, and A, and it gave Balatro the relatively low E10+ rating.
Thanks, I hate it. One more set of batteries, one more flaky wireless link to troubleshoot. Please take all those fancy electronics, and put them inside the phone where they belong.
