On desktop, move your mouse left and right to aim, then click to drop. On mobile, touch and drag to position, then release to drop.

Strategies

Build a stable base with the largest planets at the bottom center. Cluster identical planets together so every drop has a merge partner. When the stack gets crowded, prioritize any available merge over setting up the perfect chain.
