The difficulty level at GoldDiggerGames.ca is measured by how difficult it is to win the prize.
For example, if there is 1 prospector shown, then it is very easy to win the prize.
If the difficulty level shows 5 prospectors, then it would be very hard to win the prize.

If you do not know this classic game here is a brief summary of the rules:
Your playing board is a 9x9 grid. Some of the grid cells are already filled in and you should fill in the remaining cells with the correct numbers between 1 and 9.
The grid should be completed according to the following guidelines:
Numbers between 1-9 can appear only once in each row.
Numbers between 1-9 can appear only once in each column.
Numbers between 1-9 can appear only once in each region (3x3 fields).
If a number occurs more than once in a row, column or region the game grid is invalid.
