To qualify for placement on a Game Leaderboard, you will need to play a minimum of 10 games. Once you play the minimum number of games, you will start seeing your rank on the Leaderboard.
Your leaderboard placement is determined by the amount of wins you accumulate from the games you play. In the event of a tie, the Penguin with the higher win percentage will be placed higher on the leaderboard.
The main leaderboard will reset every Monday at 12 a.m. Penguin Standard Time. There is also an "All Time" Leaderboard that does not reset, and displays the Penguins who rank the highest all-time respectively in each leaderboard.
If you are able to reach the top 10 on any Game Leaderboard, you will receive the Leaderboard Star stamp. If you are able to finish at the top of any leaderboard come reset time, you will receive the extreme Top of the Charts stamp.
In addition to the Leaderboard stamps, the player who finishes ranked first in any game will receive a shiny golden pin with the game that they have ranked first in as well as a trophy hand item. This player will also receive a reward bonus for every minigame during the following week.
Note: It may take some time to receive your rewards for Leaderboard placement as they are not distributed automatically. Instead, these rewards are distributed manually by the Club Penguin Legacy Team.
