While the Clan War search is ongoing, Co-Leaders or Leaders can cancel the war search at any time, but once a match is found, canceling the war can no longer be done and the war enters its preparation day. Once a Co-Leader or Leader starts a Clan war search, the clan is put into the matchmaking pool, and it may take anywhere from a few minutes to a few hours for the matchmaking process to find a suitable clan in war.The matchmaking system in Clan Wars puts your clan against another clan of similar strength both offensively and defensively, and of the same size, rounded down to multiples of five (or ten if member amount is 30+)eligible members.The bonus can be increased by winning attacks, but most of it is lost if your clan loses the war. Bonus loot is your prize for winning the war. Each epic 47 hour event (23 hour preparation + 24 hour battle day) is won by the clan who scores more stars.Clan Wars is a feature that was added in the Version 6.56.1 update.
