You get more fame every time you win a Tombs game. It increases with consecutive wins:
1 = 1
2 = 2
3 = 3
4= 4
5 = 6
6 = 8
7= 12
8 = 16
9 = 20
10 = 24
11 = 28
12 = 32
13 = 36
14 = 40 (40 thereafter)
Rank requires the following amount of fame:
1 = 25
2 = 75
3 = 180 (Deer emote)
4 = 360
5 = 600
6 = 1000 (Wolf emote)
7 = 1680
8 = 2800
9 = 4700 (Tiger emote)
10 = 7750
11 = 11900
12 = 20000 (Dragon? emote)
13 = 34500
14 = 65000
15 = 100000
You get cool emotes at rank 3 and above if you type "emote" in the chat bar.
