About Split Brain
Two games. Two thumbs. At once.
Split Brain is a coordination stress-test that asks each hand to play a completely different game at the same time. Your left thumb keeps a bouncing dot alive so it never touches the top or bottom, while your right thumb taps glowing targets before their timers expire. Doing either alone is trivial; doing both together is where your brain quietly falls apart — which is exactly the point. You are scored on the seconds you survive, and practice genuinely barely helps.
How to play Split Brain
- LEFT side: tap to push the dot up so it never hits the top or bottom.
- RIGHT side: tap the glowing target before its timer runs out.
- You must do BOTH at the same time. Your brain will hate this.
- Survive as long as you can. Practice barely helps — that's the point.
Tips & strategy
- Set a steady left-hand rhythm first, then layer the right-hand taps on top of it.
- Don’t stare at the target — keep your gaze centred and use peripheral vision for both sides.
- When you feel overwhelmed, prioritise the bouncing dot; a dropped target only costs points, a dropped dot ends the run.
- Treat the two sides as one rhythm rather than two jobs. Pick a tempo where a left-hand bounce and a right-hand tap alternate predictably and your hands stop competing for attention.
