Bounce Reactor

Merge parts, boost bonuses, and grow your powerful drop machine

Build your own drop machine and make it stronger piece by piece.
Merge identical parts on the grid to upgrade their power, then place them into the machine for better results.
Balls fall automatically, bounce between obstacles, and generate progress as they travel through your design.
Expand the board, unlock new slots, and customize the look of your setup as it grows.
A calm merge-idle experience with clean visuals, light physics, and steady progression — perfect for relaxing sessions.
