Anode is a new entry in the falling-block puzzle genre developed by Kittehface Software. Players align falling blocks of matching colors to create chains that can be detonated, clearing space in the playfield. The game introduces mechanics like linking blocks across each other and matching angled couplers for multi-color chain reactions.

Anode includes a Mission Mode with randomly generated objectives and global leaderboards for competitive play. Local multiplayer supports two players, with an option for one-keyboard play. The game features a dynamic soundtrack that intensifies as the playfield fills.
