What is the Sequence in Drop7?

Question

In Drop7's Sequence mode, what is the full sequence of discs that are dropped? Has this been documented by anyone? I've seen mentions that there definitely is a sequence to the numbers, but not exactly what it is. I'm assuming the person seen in the below video did figure out the sequence if they achieved a score of 5,000,000.

Answer 1

Here are the first 261 pieces you drop (COMPLETE)

2 1 1 6? 4 5 5? 5? 1? 6 1 5 7 5 3 6 3 2? 6 4? 2 5 7 1 2? 5 1? 3? 2? 4

5 5 2? 1? 6? 2? 3 2 3 2? 3? 6 2 7 7 6 3? 2? 6? 4 7 4 5 4 3 6 1 6? 1

5 7? 4 6 3 5? 7 4 3 5 2 6? 2 7 2 1 4 7 4? 4 2 7 3 5? 5 5 1? 7?

7 7? 2 7? 2 3? 2 3 2? 2 6? 5? 4? 6? 5 7? 2 6 7? 7? 5? 4 2 3? 7 2 3

2? 1 3? 4 1 3? 1? 1 6 1? 5 7 5? 2 5 5 6? 3 5? 4? 5 7 4 1 3? 5

1 6 4 7? 3 7 3 7 7? 4 4? 1 5 1? 5 1 4? 4 3? 4 7 4 3 1 4? 5 5?

7? 5? 5? 1 3 6? 2? 2 3 7 5 4 5 6 1 6 7? 1 1 2? 7 3 7 2

2? 7? 7 4? 6? 5 7 5 7 6? 7 4 6 5 1 6? 3 4 7? 7 5 2 6

1 3 7? 6 4 7 3 7 6? 5 5? 6 2 4 3 3 5? 7 4? 7 1? 5?

4 3? 6 5 7? 1? 7 1 5 6 1 7 4? 6 3 6 1 1 1? 5 6

Question mark signifies not visible.

Answer 2

I'll start this by saying that I worked on a port of the game to WP7 (and have my own personal Xbox 360 version) that was never released, so I can't come right out with the information requested.

I feel like I can give a few comments though.

That video you posted shows the sequence, if you wanted to document it, you can get all of the information right from the video, at least to that point. you could try an alternate path if you can analyze where that person made mistakes.

I can also probably say that I originally thought this was just a random number generator seeded with the same seed, but it is actually a defined set of values that are pulled from in a large data table in the app, I suppose so it could be the same cross-platform which wouldn't be the case with different system random number generators. So you could pull the sequence from the executable image if you can get it on a PC and figure out where that data is.

Maybe that's a pointer in the right direction. Hope this helps.

Answer 3

If there is a (x) behind a number the piece is not visible. If there is a question mark, ?, where there is suppose to be a number I don't know witch number is behind the block yet.

The starting row is: 6(x),4(x),5(x),7(x),5(x),1(x),3(x)

Que:

Level 1:
2,1,1,6(x),4,5,5(x),5(x),1(x),6,1,5,7,5,3,6,3,2(x),6,4(x),2,5,7,1,2(x),5,1(x),?(x),2(x),4

Level 2:
5,5,2(x),1(x),6(x),?(x),3,2,3,?(x),?(x),6,2,7,7,6,3(x),?(x),4,7,4,5,4,3,6,1,?(x),1

Level 3:
5,?(x),4,6,3,?(x),7,4,3,5,2,6(x),2,7,2,1,4,7,?(x),4,2,7,3,?(x),5,5,?(x),?(x)

Level 4:
7,?(x),2,?(x),2,?(x),2,3,?(x),2,6(x),?(x),?(x),?(x),5,?(x),2,6,?(x),?(x),?(x),4,2,?(x),7,2,3,?(x)

Level 5:
1,?(x),4,1,3(x),1(x),1,6,?(x),5,7,5(x),2,5,5,?(x),3,?(x),?(x),5,7,4,1,?(x),5,

Level 6:
1,6,4,7(x),3,7,3,7,7(x),4,?(x),1,5,?(x),5,1,?(x),4,3(x),4,7,4,3,1,?(x)

Level 7:
5,?(x),?(x),?(x),5(x),1,3,?(x),?(x),2,3,7,5,4,5,6,1,6,7(x),1,1,?(x),7,3

Level 8:
7,2,?(x),?(x),7,?(x),6(x),5,7,5,7,?(x),7,4,6,5,1,?(x),3,4,?(x),7,5

Level 9:
2,6,1,3,7(x),6,4,7,3,7,?(x),5,?(x),6,2,4,3,3,?(x),7,?(x),7

Level 10:
?(x),?(x),4,?(x),6,5,1(x),?(x),7,1,5,6,1,7,?(x),6,3,6,1,1,?(x),5

Level 11:
6,4,7,7,4,?(x),?(x),?(x),?(x),4(x),4(x),?(x),?(x),4,?(x),3,?(x),1,?(x)

Level 12:
7,2,7,?(x),?(x),6,?(x),2(x),4,6,2,2,5,5,7,1,7,?(x),3,7

Level 13:

Comment or message me if you have additional information or find that some of the information is incorrect.

I got this information from Android (My Galaxy Nexus ICS). I quess it is the same on the different platforms if not then we need to seperate the thread.

Answer 4

I figured out the discs in sequence mode for the first 71 levels:
