阻碍模式
阻碍模式（Block）是一个玩家对战模式，游戏目标是将所有其他玩家丢进冻结区域，侧重点在于走位和快速反应。该模式通常使用定制的地图，一般是一些精选的热度高受欢迎的地图。
游戏机制
地图特性
许多阻碍模式地图有一条通往终点线的跑道。
- 跑道可以有多条分支，可以从出生点或者主干道分流。
- 通常来说，抵达终点的玩家会获得能力提升和武器（有些地图则会在获取武器前设置一项额外挑战）。
- 地图中一般会有一个主战场，用于玩家开展阻碍行动，这个主区域离出生点有一小段距离，因此玩家不会在其中复活。

Server Complications
Teeworlds block servers have been in a long-winded state of rivalry, leading to the birth and death of many servers over time. A number of allegations, some evidenced and some not, have been made against various owners in regards to DDoS attacks.
Block Community
Block, being a heavily PvP centered mode, can harbor toxic attitudes, although this isn't necessarily specific to block.
Block has no single dominant server network - apart from popular servers such as Bombay, block players can be seen on servers like Law Multimap servers and the Multeasymap Playground on DDrace.
