Marathon 2020
To celebrate the coming of the year 2020, I've created a new "extended Tetris the Grand Master" mode where the level counter goes up twice as far as normal, all the way up to 2020.
Gameplay
The goal of this game is to reach the end at level 2020.
Every piece placed increases the level by 1, and every line cleared also increases the level by 1, with bonuses for large numbers of lines:
| Lines cleared | Levels advanced |
|---|---|
| 1 | 1 |
| 2 | 2 |
| 3 | 4 |
| 4 | 6 |
When the current level reaches one less than the level at the bottom of the display (usually a multiple of 100), the level will not advance until a line is cleared.
Levels
Each section is 100 levels long, except for the last section, whose levels go from 1900 all the way to 2020.
However, it is possible to be stopped early on if you do not play fast enough.
Torikans
There are certain checkpoints at which your current time will be checked and you will be stopped if your time is over a set objective time.
| Level | Time limit |
|---|---|
| 500 | 6:00.00 |
| 900 | 8:30.00 |
| 1000 | 8:45.00 |
| 1500 | 11:30.00 |
| 1900 | 13:15.00 |
At levels 500, 1000, and 1500, you will be stopped immediately if your time is not under the objective.
At levels 900 and 1900, the next section will be capped at 999 or 1999 respectively, and you will get a short credit roll when the section is over.
Speed
Marathon 2020 gets faster in two different, independent ways, the gravity curve and the delay curve.
The gravity curve is always the same at a particular level, while the delay curve can vary based on your previous section time.
Gravity Curve
The gravity curve is the same as it is in the original TGM and TAP.
Delay Curve
The delay curve is shown as in the following table. Line ARE is always equal to ARE.
If your time in a particular section from 0 to 70 is smaller than the "cool" requirement at that level, your delay curve will be bumped up an extra level at the end of the section.
The delay curve always advances at least 1 level past level 500, and if you get a section cool when the level is past 500, it will advance 2 levels instead.
| Level | ARE | Lock | DAS | Line | Cool |
|---|---|---|---|---|---|
| 0 | 27 | 30 | 15 | 40 | 45.00 |
| 100 | 24 | 30 | 12 | 25 | 41.50 |
| 200 | 21 | 30 | 12 | 25 | 38.50 |
| 300 | 18 | 30 | 9 | 20 | 35.00 |
| 400 | 16 | 30 | 9 | 15 | 32.50 |
| 500 | 14 | 30 | 8 | 12 | 29.20 |
| 600 | 12 | 26 | 8 | 12 | 27.20 |
| 700 | 10 | 22 | 8 | 8 | 24.80 |
| 800 | 8 | 19 | 7 | 8 | 22.80 |
| 900 | 6 | 17 | 7 | 6 | 20.60 |
| 1000 | 6 | 15 | 6 | 6 | 19.60 |
| 1100 | 6 | 15 | 6 | 4 | 19.40 |
| 1200 | 6 | 15 | 6 | 4 | 19.40 |
| 1300 | 5 | 15 | 5 | 4 | 18.40 |
| 1400 | 5 | 15 | 5 | 2 | 18.20 |
| 1500 | 4 | 15 | 4 | 2 | 16.20 |
| 1600 | 4 | 13 | 4 | 2 | 16.20 |
| 1700 | 4 | 11 | 4 | 2 | 16.20 |
| 1800 | 4 | 10 | 4 | 2 | 16.20 |
| 1900 | 4 | 9 | 4 | 2 | 16.20 |
| 2000 | 4 | 8 | 3 | 2 | 15.20 |
In order to get a section cool, your 0-70 section time must be below the cutoff and no more than 2 seconds slower than your previous 0-70 time.
Grading
Basic grades
Internally, the grade counter is a number that can range from 0 to 30.
At the beginning of the game, it starts at 0. To increase it, you must bring an internal grade point counter past a certain threshold.
The threshold is set at 50 points for the first grade, then 100 more points for the next grade, then 150 points for the grade after that, and so on. You reach the maximum level of 30 at a total of 23,250 points.
A table of the thresholds in grade points required to reach each level is provided below:
| Grade | Threshold |
|---|---|
| 0 | 0 |
| 1 | 50 |
| 2 | 150 |
| 3 | 300 |
| 4 | 500 |
| 5 | 750 |
| 6 | 1050 |
| 7 | 1400 |
| 8 | 1800 |
| 9 | 2250 |
| 10 | 2750 |
| 11 | 3300 |
| 12 | 3900 |
| 13 | 4550 |
| 14 | 5250 |
| 15 | 6000 |
| 16 | 6800 |
| 17 | 7650 |
| 18 | 8550 |
| 19 | 9500 |
| 20 | 10500 |
| 21 | 11550 |

| 27 | 18900 |
| 28 | 20300 |
| 29 | 21750 |
| 30 | 23250 |
Points are given according to a different scale, the point level. The point level is calculated by taking your current actual level, and adding (100 * the delay level) to it.
The points given for clearing certain amounts of lines is given as follows:
| Level | x1 | x2 | x3 | x4 |
|---|---|---|---|---|
| 0 | 10 | 20 | 30 | 40 |
| 100 | 10 | 20 | 30 | 40 |
| 200 | 10 | 20 | 30 | 48 |
| 300 | 10 | 20 | 30 | 60 |
| 400 | 10 | 20 | 36 | 72 |
| 500 | 10 | 21 | 42 | 84 |
| 600 | 10 | 24 | 48 | 96 |
| 700 | 10 | 27 | 54 | 108 |
| 800 | 10 | 30 | 60 | 120 |
| 900 | 11 | 33 | 66 | 140 |
| 1000 | 12 | 36 | 72 | 160 |

| 1700 | 19 | 60 | 135 | 300 |
| 1800 | 20 | 64 | 144 | 320 |
| 1900 | 21 | 68 | 153 | 340 |
| 2000 | 22 | 72 | 162 | 360 |
| 2100 | 23 | 76 | 171 | 380 |
| 2200 | 24 | 80 | 180 | 400 |
| 2300 | 25 | 84 | 189 | 420 |
| 2400 | 26 | 88 | 198 | 440 |
| 2500 | 27 | 92 | 207 | 460 |
| 2600 | 28 | 96 | 216 | 480 |
| 2700 | 29 | 100 | 225 | 500 |
| 2800 | 30 | 104 | 234 | 520 |
| 2900 | 31 | 108 | 243 | 540 |
| 3000 | 32 | 112 | 252 | 560 |
| 3100 | 33 | 116 | 261 | 580 |
| 3200 | 34 | 120 | 270 | 600 |
| 3300 | 35 | 124 | 279 | 620 |
| 3400 | 36 | 128 | 288 | 640 |
| 3500 | 37 | 132 | 297 | 660 |
| 3600 | 38 | 136 | 306 | 680 |

| 3800 | 40 | 144 | 324 | 720 |
| 3900 | 41 | 148 | 333 | 740 |
Past level 1000, a 4-line clear will always give (30 * current grade), regardless of point level.
The remaining 20 grades come from section cools. Every section cool you get boosts your score by one grade. There are no regrets.
Points are also taken away with the time it takes to lock down a piece. The delay counter starts at 0, and increases by (current grade + 2) every frame. When the counter reaches or exceeds 240, it resets to 0, and 1 grade point is taken away.
Grades are based on the maximum grade points achieved. Once a grade has been attained, it cannot be lost even if grade points drop below the threshold for that grade.
