Rank progression

Solving puzzles gives you points, the more points you score the higher your rank is. Top 20 players are displayed on the leaderboard. Only the top player has his rank changed into Sovereign. Being the first to solve a new challange gives a big bonus of points, called the firstblood bonus. Alongside this there is a time bonus catered to each challange. You will get points for solving a challange only once.
