Brain Merge — Grow a Galaxy Brain
Brain Merge is the big-brain version of the fruit merge puzzle. Drop tiny neurons into the box and merge matching minds into ever-smarter brains — mouse brain, monkey brain, human brain — until you achieve the mythical Galaxy Brain. Free in your browser, no download.
How to play
- Aim — slide your finger (or move your mouse) left and right.
- Drop — release or click to drop. On a keyboard, use arrow keys and space.
- Merge — two identical pieces merge into the next tier and score points.
- Survive — keep the pile below the dashed danger line!
The merge chain
Neuron → Synapse → Mouse Brain → Bird Brain → Cat Brain → Dog Brain → Monkey Brain → Human Brain → Genius Brain → Mega Brain → Galaxy Brain 🌌
Eleven levels of intelligence. You can only drop the five smallest minds — every bigger brain must be earned by merging. Two Galaxy Brains merged together ascend beyond the game for a huge bonus.
