It's interesting that the three puzzles with the most incorrect attempts can all be looked up on OEIS.

Day 15 - - "number of ways of factoring n with all factors greater than 1"

Day 4 - - "number of ways to tile a 2 × (n-1) rectangle with 1 × 2 dominoes and 2 × 2 squares"

Day 2 - - "number of nondegenerate triangles that can be made from rods of length 1,2,3,4,...,n"
