3D Lines and Blocks - Version 1.0 3D Lines and Blocks is a new approach of well-known classic games Lines. Without changing the rules, we made 3D-environment with different special effects and many opportunities. We also added a new game mode - Blocks. If you go tired of playing the game with classic Lines rules, you can play Blocks. This mode has slightly changed rules, so you should form not lines but blocks with balls. This makes the game even more interesting and exciting.
