Welcome to the New Zealand Beaver Challenge 2023! We will be ready for registrations at the start of February, and this year the competition for Aoteaora New Zealand will be available from 13 March to 24 March.

This challenge tests your logic and computational skills through different types of fun and challenging problems.

The problems come in three levels of difficulty: A, B and C. 

The "A"-level problems are intended to be easier than the "B"-level problems, which are intended to be easier than the "C"-level problems.

You can find a problem's difficulty in the problem overview before you click on it.  The difficulty of a problem determines how it will be scored.  The scoring rules are as follows:  

Difficulty Correct Incorrect Unanswered
A +6 points -2 points 0 points
B +9 points -3 points 0 points
C +12 points -4 points 0 points
