Some of these are not words, this guy sucks at scrabble.
“_M” is the only one that’s bad as far as I can tell.
“AS” bottom-up is probably fine? I don’t know the rules. The words it could turn into by adding “racist” or “rapist” would be valid words, “sac” and “sap”.
_M has a tile above it, meaning this can be anything. There are plenty of words that end in _m.
Scam, scum, slum, plum, trim, tram,
The only bad one is SA
Let’s pretend the game started with rapist/racist and this is showing how it could progress either way and work?? Maybe? Idk I also suck at scrabble
you forgot about “ra” and “ist”, but the point is that those three are about to be completed, so all words are correct
