Tetris: The Grand Master is the first arcade game in Arika's TGM series.

Speed

ARE is fixed at 30 frames.

DAS is fixed at 15 frames.

Lock time is fixed at (somebody look this up).

Line Clear time is fixed at (somebody look this up).

Gravity is dependent on the level, and it ranges as follows: (somebody double check this).

Level Speed
0 to 199 1/60G to 1/2G
200 to 299 1/60G (yes, it slows down at this point) to 1G
300 to 499 2G to 5G
500 to 999 20G

The player can force constant 20G, by pressing ↓↓↓↓ ↓↓↓↓ C B A before starting the game, though this will exclude their play from the highscore list. Unlike TGM2, the lockdown time, spawn delay and DAS time do not change throughout the game.

Scoring

In TGM1 you get points exclusively for clearing lines. You get more points for clearing more lines at once, with an additional bonus awarded for combos, bravos, and forcing your pieces down. As the level increases line clears increase in value, placing particular importance in the final stretch. Incidentally, for all players good enough to attain S9 score becomes irrelevant. Nevertheless, here is a more technical description of the scoring formula:

Score = ((Level + Lines)/4 + Drop) x Lines x Combo x Bravo

Where:

  • Level is the current level you are on.
  • Lines is the number of lines you just cleared.
  • (Level + Lines)/4 is rounded up.
  • Drop is the number of spaces you manually dropped the piece. The last space your piece falls does not contribute to this, however locking the piece once it has landed will add 1 to the Drop.
  • Combo returns to 1 by default every time a piece does not clear lines. Otherwise, it is :
    Combo = Combo - 1 + (2 x Lines - 1)
  • Bravo is equal to 4 if this piece has cleared the screen, and otherwise is 1.

Grades

In TGM1 grade is entirely determined by score. As you pass certain milestones, TGM will assign you the next grade:

Grade Required Score Grade Required Score
9 0 S1 16,000
8 400 S2 22,000
7 800 S3 30,000
6 1,400 S4 40,000
5 2,000 S5 52,000
4 3,500 S6 66,000
3 5,500 S7 82,000
2 8,000 S8 100,000
1 12,000 S9 120,000
GM 126,000*

*In addition to this, to achieve Grand Master rank, the player must reach grade 1 before level 300, grade S4 before level 500, grade S9 before level 999, and level 999 at or before 13:30:00.
