There are two types of tournaments that players can join and get rewarded based on their rankings:
Solo tournament: Individual players will join the tournament and compete against each other to increase their rankings in the LeaderBoard. The higher their rankings are, the more rewards they will get.
Clan tournament: Clan members can participate in special clan tournaments, which have a leaderboard comparing cumulative scores from all members participating in the tournament during its duration. All clan members will receive a reward based on their clan rank when the tournament is over.
