There was a l33t tileset for Scrabble, which is currently no longer available, which contained 103 tiles:
0 points: * ×3 (wildcard)
1 point: E ×6, N ×6, R ×6, A ×4, I ×4, L ×4, O ×4, U ×4, T ×3, S ×2
2 points: 3 ×6, 1 ×5, 4 ×5, D ×4, 0 ×4, G ×3, Z ×3, 7 ×3
3 points: X ×4, B ×2, C ×2, M ×2, P ×2
4 points: F ×2, H ×2, V ×2, W ×2, Y ×2
5 points: K ×1
6 points: J ×1
10 points: Q ×1
Could something similar be ported into Scrabble3D? I think I know how to make the tileset but not the dictionary...
This one has more X's to make more l33t phrases (such as h4x0r). The numbers 3, 1, 4, 0, 7 can be used to replace E, I, A, O, T.
I was also considering adding 2 ( tiles, since ( looks similar to C. All tiles in this tileset will contain a single character, no double lettered tiles.
