We can write 333^444 as (333^4)^111.
Any number which has a units digit of 3 when raised to the power 4 has a units digit of 1.
This make 333^4 a number with a units digit of 1.
Therefore 333^4 raised to any power will continue to have a units digit of 1.
So the required units digit of 333^444 is 1.
