Tower Siege is an interactive TikTok Live game in the build-versus-destroy genre. Viewers are not split into teams: anyone can both build and demolish with different gifts. 100 likes grant a block, a subscription grants two, a Rose gift builds one block per coin, and any other gift without a special rule destroys one block per coin. A floor consists of four blocks, and the tower starts at 6 floors. Within 180 seconds the builders must raise the tower to 20 floors and hold the height for 8 seconds, otherwise the destroyers win. Actions are shown as a flying cargo or projectile, and the round ends with a contribution table. All parameters are configurable in the game console, with a demo mode and event testing without a TikTok connection.
