Almost 1,000,000 on Marathon today
Today I just beat my record on Marathon, 996,000. I did total 52 T-spin (by calculation) with all 4 line down, 153 lines, the first line was finished with T-spin which give me 12000 point instead of 1500.
Here is my calculation:
first line, 1 t-sprin, 12,000
first 4 line down, 12,000
number of back to back tetris is 37 (153-1-4)/4=37, 37x1,8000=666,000
The total score of above is 666000+12,000+12,000=690,000
My score is 996,000. So my T-sprin (exclude the 1st one) score is 996,000-690,000=306,000. Each T-sprin is 6000. 306,000/6000=51. Plus the one for the 1st line, the total T-spin is 52.
There is about 59 T-sprin you can get for each game if you play good. Here is my calculation:
There are 149 line down while the last 4 wait until it is full in the last screen. The depth is 20 lines. The width is 10. So the total area is (149+20)x10=1690. But for the last 20 lines, it can't be all use, at lease each line's width can only be 9 instead of 10, the top line has to be a room for the stick. The total maximum shape is about 1690-20-4=1666. Each shape is 4. So the numbers of the total shapes you get is 1666/4, is about 416. There are 7 shapes. So the total T you can get is 416/7= about 59.
For this game, I should only missed 8 T-sprin.
There is another method can get even high score, which is use double T-spin down. That means each T-sprin is down with 2 lines. That is 24,000 score for doing so.
