I've played legitly twice now to try and confirm this and it seems to me like they only have to be divisible by 8, not 18 - I got scores of 264 and 248 and neither is divisible by 18. I was a bit confused about why 18 was the number people mentioned regarding legit Meerca Chase Scores before I tried this as well, because the score goes up in increments of 8, but I wanted to make sure. Does this happen for anyone else or is everyone else talking about the first Meerca Chase game? - which seems odd because I think it's in the game graveyard now, right...?
