Yesterday my nerdy roommate was playing his favorite videogame. After they finished, they left me this message:

IwaendnIttocatuhgehtrusoimePnsoofkéamlonph

As well as this table which I tried to decipher without success:

201   3   2  14  11  13
201   9   1   0   0  15
201   6  12   3   5  10
201   5   4   5   4   7
201   4   8   9  10  10
201  10  13  14   3   8

???  12   6   7  13   9

The first three-digit number in the last row is missing, what could it be? I suspect it is not just a $201$: my roommate is such a nerd...

  • $\begingroup$ I can see what he went out for, but I don't know if the numbers actually relate to deducing how I should see that. $\endgroup$ – MacGyver88 Feb 12 at 15:45

Could the answer be

131?

As @Stiv pointed out, the message translates to:

I went to the ruins of alph and I caught some Pokemon

What does 201 mean:

In the Ruins of Alph you can catch the pokemon Unown, which is number 201 in the pokedex. Unowns come in different forms representing letters. Quoting Bulbapedia: "In the Generation II games, Unown's form is determined by its IVs".

What do the numbers mean:

The decimal values in the question can be converted to binary values. Each row of five 4-bit values represent the IV's.

So the result will be:

201 3 2 14 11 13 -> 201: 0011 0010 1110 1011 1101
201 9 1 0 0 15 -> 201: 1001 0001 0000 0000 1111
201 6 12 3 5 10 -> 201: 0110 1100 0011 0101 1010
201 5 4 5 4 7 -> 201: 0101 0100 0101 0100 0111
201 4 8 9 10 10 -> 201: 0100 1000 1001 1010 1010
201 10 13 14 3 8 -> 201: 1010 1101 1110 0011 1000

From Bulbapedia:
Unown's form is calculated by taking the middle two bits of the last four 4-bit values. Then add them together, convert it to decimal, dived by 10 and round the number down, then add 1, and you end up with a number corresponding to a letter:

0011 0010 1110 1011 1101 -> 01 01 11 01 10 -> 01 01110110 -> 11 -> 12
1001 0001 0000 0000 1111 -> 00 00 00 00 11 -> 00 00000011 -> 0 -> 1
0110 1100 0011 0101 1010 -> 11 10 01 10 01 -> 11 10011001 -> 15 -> 16
0101 0100 0101 0100 0111 -> 10 10 10 10 11 -> 10 10101011 -> 17 -> 18
0100 1000 1001 1010 1010 -> 10 00 00 01 01 -> 10 00000101 -> 0 -> 1
1010 1101 1110 0011 1000 -> 01 10 11 01 00 -> 01 10110100 -> 18 -> 19
12 1 16 18 1 19 translates to Lapras

Lapras' pokedex number is 131, so I think the answer is 131, and the numbers behind 131 are the IV-values of Lapras.

  • $\begingroup$ Oh, well done sir! I spotted what the 5 values likely represented (A, D, SA, SD, S) and then got stuck, having totally forgotten that you could use those for any real purpose re the 'mon in question (d'oh!). Well done for wrapping this one up so thoroughly... +1 $\endgroup$ – Stiv Feb 12 at 21:52
  • $\begingroup$ Well done David, you were so fast. Congrats on your first accepted answer! $\endgroup$ – melfnt Feb 12 at 22:01

Partial guess:

The message has 42 letters and there are 42 numbers in the grid (including '???').
The puzzle is about a video game and the tangle of letters includes the word
Pokémon
