How to read it: find your total down the side, the dealer’s upcard across the top. D means double if allowed, otherwise hit; Ds means double if allowed, otherwise stand. The lab’s drill mode serves you these cells as flashcards and remembers the ones you miss. One honest gap: the engine does not model surrender yet, so rule sets with surrender are incomplete here - this page says so rather than hides it.
