All Back to Basics levels can and should be played and reviewed from January 1st to February 28th. The actual author of each level will not be made public until then.
Every player can use the competition form to submit their guesses on who built which level. Please note that once you sent the competition form no further corrections or newly submitted form will be taken into account. On March 1st the three players who guessed most levels with their corresponding authors right will be announced as the winners.
On March 1st, the scores from the trle.net rating system will be used to calculate the winning levels of the competition. The highest and the lowest scores will be eliminated to form the final rating. The level with the highest final rating will win the competition.
