Gabudoku

Inspired by the Shadoks, an old cartoon about dumb space birds who can only count up to 4, this is a simple Sudoku that replaces numbers with their numbering system. 

Instead of 0-1-2-3-4-etc, it goes Ga-Bu-Zo-Meu-Buga-Bubu-Buzo-etc.

Like a normal sudoku, your goal is to fill the grid without repeating numbers in a row, box or line.

There's 4 levels, starting with a simpler 4x4 Sudoku up to a 9x9 with Anti-King rules. The Anti-King rules adds the complexity of not having any identical number touching each other, even diagonally. 

If you feel normal Sudoku is too easy, try this variant.

Good gabuzoluck!
