Fusion Reactor

Fusion Reactor is a cosmic block puzzle. Drag pieces from the tray onto the board with your mouse or finger and press R or F while dragging to rotate them within each piece's 360-degree budget. Link 8 or more same-colored blocks to trigger a fusion blast that clears them and leaves a seed behind. Fill rows and columns to build score-multiplying chains; three chains unleash Overdrive for double points. Classic mode is pure survival, while Challenge mode adds an erosion timer and upgrade talents.
