Casual worlds are a safer and friendlier environment to learn Tribal Wars in. One of the biggest differences is that you cannot lose your starting village. To start on a Casual world you have to either play on a normal world for 14 days or be conquered ("nobled") on such a world. Casual worlds have a limited run-time. After several months the settings gradually change and the world slowly transforms into a normal world. Casual worlds started in 2017 and later end after about 18 months.
