I have a suggestion or an idea that probably has been here before.
Rookie Puzzles - 1 point
Expert Puzzles - 2 points
Pro Puzzles - 3 points
BH - 4 points
With this system you encourage difficult puzzles but on the other had it might lead to waiting puzzles to be moved to a higher level so more points will get scored...
I don't fully agree with this.
My suggestion would to have a one/two point per puzzle like now, but to have several different groups of points:
let's say rookie points, expert points, pro points, BH points.
Provided a rookie solves a long forgotten BH puzzle - he gets one BH point. An expert solving one pro puzzle gets one pro point and so on.
The points (1-2) per correct answer would be just like they are now, buf the diversification would better represent the skills of solving puzzles of different levels, imho.
