[NES] Tetris Score Statistics

I got interested in how to get a higher score in Tetris for the NES, so I started thinking at what level to start to get the highest possible score. I also wondered how the line penalties after level 9 affected the final score outcome. I wrote some code to calculate the maximum possible score for each level. This is what came out of it:

Notes:
Soft drop points are ignored.
The scores are calculated at the end of each level.
A perfect game of all tetrises is so unlikely that we can say it's impossible.

Slight corrections:

When you advance to the next level with a line score, you do get the points for the newly attained level, rather than the level you were on when you got it.

So for example on a level 9 start, the 25th tetris would get you 100 lines, taking you to level 10, and you get the level 10 points for it. So you'd get 288,000 at level 9, and 301,200 at 100 lines entering level 10 (not to mention the addition of soft drop points, but nevermind that).

Also, if you start on level 10-19, the level advance does not happen at 100 lines. They calibrated it so that you would get a little bit of a bonus for starting higher, but not so much of a bonus that it was easy to max the score out.

Here are the level-advance # of lines for each starting level after 9:

10 100
11 100
12 100
13 100
14 100
15 100
16 110
17 120
18 130
19 140

Incidentally the best start I've ever had is a level 9 start where I missed only 1 possible tetris before getting to level 10. Eventually I'd love to record a perfect level 9 game. I'd estimate it's no better than a 1 in 100 chance if you play perfectly.

Thank you for the corrections! I'll poke around in the code and try to get this corrected and add that soft drop points are ignored in the notes.

5. Xerxius

If you ever get a perfect level 9, then I hope you record it. It would be an amazing watch.

Sure. Since I was on a roll, I went ahead and did some calcs myself. Fun fact - a level 15 start has the latest earliest possible maxout level of the level 9+ starts at 24.4.

Code:
Strt	#Tetr	LvMx	TotSc
9	59	23.6	 1,020,000
10	56	23.4	 1,000,800
11	54	23.6	 1,008,000
12	52	23.8	 1,012,800
13	50	24.0	 1,015,200
14	48	24.2	 1,014,000
15	46	24.4	 1,010,400
16	45	24.0	 1,009,200
17	44	23.6	 1,011,600
18	43	23.2	 1,017,600
19	42	22.8	 1,027,200

Intriguingly, you could do it with one fewer tetris on a level 19 start by "soft-dropping" every block! But good luck with all that.

Also interesting is that level 19 is the only level where you could max it out quicker by making your final score a non-tetris - even a single line would suffice. So it would be level 22 5 lines in, instead of 8. So there you go - you only need 41 tetrises in a row starting on level 19!

I will definitely record - that would be quite a tragedy not to have on record!

I've had this spreadsheet called Tetris100% kicking around for a while -- of note, it also highlights perfect transition and kill-screen scores.

Very nice, though I see it does make a couple of mistakes.

One is the thing I mentioned about when you reach a new level, it's not giving you the points for a tetris on the newly attained level, which the game does. To fix the code you could just add 4 to your cell reference, eg. INT((a3+4)/10.

Also, starting at level 10, you need to add 1 to your index for 'before normal progression', and then you'll be in good shape.

11. Kitaru

I remember thinking about scoring at the level reached rather than the one you were on before, but I must not have finished that line of thinking and implemented it in the spreadsheet. I took this opportunity to clean up the spreadsheet logic significantly. If you notice any other errors, please let me know.

12. DonAtreides

I think it's interesting. Thanks for posting!

13. wasmachstdugern

whoa. i had a 660k transition starting at 18 today- i was only 90k off the highest possible?!? i promptly proceeded to fuck the game up and ended w/708k but man that was close.

14. Raul1138

I have found this to be a valuable resource for reference.

For me to remember and handily copy and paste the order of scoring potential:

19, 18, 9, 17, 11, 10, 8, 12, 13, 16, 7, 14, 15.
