Mini World Changes were implemented in the Winter Update 2011. Just as World Changes do, they allow for a more dynamic shaping of the Tibian world but unlike them, these cannot be triggered through actions made by Players. These changes happen somewhat rarely and do not come with warnings. They last a few hours. NPC Towncryer tells you about these mini changes, by shouting a message. Since Updates/10.2 it's also possible to check which MWCs are active on the World Board at the Adventurer's Guild.
There are a total of 24 MWCs. At the initial release of Mini World changes with update 9.4, 12 were implemented. With update 9.6 three additional MWCs were introduced. Afterwards one with update 10.1, one with update 10.2 and one with update 10.37. Then, with update 10.8 another 6 MWCs were implemented.
Through some empirical research it became very likely not every Mini World Change has the same chance of occurring. Therefore statistics have been gathered which can be seen below. This is a working project since more statistics need to be added to get accurate data. To gather this data a character needs to check the World Board once every 24 hours, which can be done on multiple worlds. A total varying between zero and eight MWC at the same time have been encountered.
