What you get
99 spots per game
Topping a board is worth 99 points, second is 98, on down to 1 point for 99th. Miss the 99 and the run scores nothing, which is what makes the cut mean something.
Every board counts the same
Winning any game's board is 99 points, whichever game it is. Your overall rank is those placings added up, so there's no single title you have to grind.
Sign in to be counted
Scores post as the signed-in player, so an account is what turns a good run into a ranked one. Play signed out and the run simply isn't recorded.
More games worth ranking in
Games that already have scores posted against them, plus those built to be played for a score — high-score chases, time attacks, head-to-head.
