Each of our Arctic Shores practice games, apart from Balloon, ends with a score out of 100. It is our own measure of how well you did that task on that run, built from what the task rewards, such as accuracy, speed or how far you got. Every game weighs these differently, so a 60 on one game and a 60 on another are not the same result. Compare a score only with other scores on the same game.
After a game we also show a percentile: the share of saved practice sessions on that game that your score beat. The charts below show the same kind of spread, counted more strictly (see how we counted, further down), so they will not match it exactly.
