I was playing TGM1 trying to figure out if the scoring formula really was the one listed on the wiki: Score = ((Level + Lines)/4 + Drop) x Lines x Combo x Bravo. From what I can see this is not correct. For example I cleared 4 lines at level 16 with no combo and without pressing soft drop, this gave me 140 points when I should have had 20 according to the formula. Am I doing it wrong?
From what I understand, the TGM scoring formula was reverse engineered, and is exactly how the calculation is actually done in the game. Unfortunately, it means that it's presented in a slightly confusing way on the wiki, especially the combo part. For the 4 line clear you mentioned, the combo value is as follows: Combo = (1) + (2 x 4) - 2 = 7
