Brain Merge Guide: Reaching the Galaxy Brain
Brain Merge Guide is one of our free browser merge games — play it here. This guide covers its complete merge chain and the strategy specifics that separate it from the classic Fruit Merge.
The full merge chain
Neuron → Synapse → Mouse Brain → Bird Brain → Cat Brain → Dog Brain → Monkey Brain → Human Brain → Genius Brain → Mega Brain → Galaxy Brain
As in every Suika-style game, only the five smallest tiers ever drop from your hand — everything above must be created by merging, and the final tier is the trophy. Merging two of the final tier clears them both for a huge bonus.
Strategy for this variant
- Neurons are tiny and slip into gaps — use them to fill holes beside the wall rather than dropping them on top of big brains.
- The jump from Human Brain to Genius Brain is where boards usually die: from that point, one corner must stay reserved for your biggest brain at all times.
- The sparkly tiers (Genius and up) are physically huge. Flatten your board before you create one, or its landing hop will scatter everything.
Universal fundamentals
The core skills are the same across all our games: keep your biggest piece in a corner, maintain a size gradient across the box, never bury the small pieces, and engineer chain reactions. For the full treatment, read our 10 tips guide and the watermelon strategy — every tactic transfers directly.
