BuildDown is a free-to-play Android game developed by Rumor Games LLC. It is a falling-block puzzle game that offers a new and exciting twist to the traditional Match 3 games. The objective of the game is to merge a cascade of colors to build denser and denser blocks before banishing them down the screen to eliminate them.

The game introduces a new way of matching colors by tapping and matching them to build denser blocks. Once the blocks are built, players can line them up in a row to finish them off. Players can activate powerups to blast away blocks, stop time, and arrange clever combos. In addition, players can shake loose more blocks to play at their own pace. The game offers ModXP to players just for playing, unlocking Modifiers that remix the game in fun and creative ways.

Overall, BuildDown offers a refreshing take on the classic Match 3 games with its innovative gameplay, new mechanics, and creative powerups. It is a must-try for puzzle game enthusiasts who are looking for a new challenge.
