Vaki Ratings

Some vakians are better than others at solving vaki puzzles. They can solve bigger and more difficult puzzles, faster and with fewer mistakes.

Simon, our simplest robo solver has a rating of 629. He is very good at the most basic puzzles (3x3 easier) but makes lots of mistakes with anything bigger or harder. This outweighs the benefit he gets from moving quickly so that for Simon to score over 600 in anything over than a 3x3 easier vaki puzzle is a fluke.

Jim, our slightly more spohisticated roboplayer has a rating of 2239. He gets this score, on average, when he solves a 5x5 harder puzzle. With these puzzles he makes, on average, four mistakes.

If your rating is better than Jim's you are ready for the challenge of vaki kal-toh, the hardest logic puzzle.

How We Calculate Ratings

We calculate ratings as the average of the top 20 vaki puzzle scores (over zero) for completed puzzles that you have recorded in the previous six months in 'just me' play.

If you have completed fewer than ten puzzles then the total of your scores is divided by twice the number of puzzles you have completed (i.e if you have completed four puzzles the total score is divided by eight)

Vaki Puzzle Ratings

The tables list the top rated open (all age), under 18, under 16, and under 14 players. Scores of over 1,000 are expected when a 4x4 puzzle is solved without mistakes. Scores of over 2,000 require a 5x5 puzzle to be solved.
