In Britain we have “reception” (when you’re aged 4-5) which is the first year of primary school, and I assumed equivalent to your kindergarten. I don’t recall there being much formal education in the same way as there is for the rest of school, but it was definitely more structured than preschool/nursery/playgroup that you’d go to beforehand.
The quick check is to search for a game on Proton DB and see how well it runs (usually pretty well!)
