Gemini Protocol
Decouple your hands. Synchronize your mind.
How to play Gemini Protocol
LEFT side, keys A/D or a thumb dragged across the lanes: dodge obstacles as they come down the lanes. RIGHT side, mouse or taps: collect orbs and avoid the red decoys.
Both sides drain one shared timer. On a phone or tablet you play with both thumbs at once: one drags on the left half while the other taps orbs on the right.
What it trains: dual-task multitasking
Gemini Protocol splits the screen and your attention with it: the left hand dodges obstacles across the lanes while the right hand steers the cursor through orbs and decoys. Both sides draw on one shared timer, so neither task can be parked.
Running two continuous tasks in parallel is one of the hardest attention demands there is — the game makes the cost of every attention switch immediately visible.
Does brain training work? →Based on the dual-task paradigm
Dual-task experiments measure what happens when people do two things at once. Even with very simple tasks, performance drops when both have to be handled together, and the classic lab version pairs two quick responses in rapid succession to show where the bottleneck sits.
Gemini Protocol turns that into two continuous tasks rather than two quick responses: one hand dodges obstacles on the left while the other collects orbs and avoids decoys on the right, and both draw on one shared timer. That makes it a training game built on the dual-task idea, not a replication of the lab procedure.

Scoring & progression
Runs are short and scored — your best run sets your personal record. Strong runs feed your belt progression in the focus discipline — from white belt toward black — and your place on the global leaderboard.
Gemini Protocol FAQ
Is Gemini Protocol free to play?
Yes. Gemini Protocol runs in your browser with nothing to download, and you can play it without an account. An account only saves your scores, stats and leaderboard place.
How long does a run of Gemini Protocol take?
A run starts with 45 seconds on the clock. Good play refills it (up to 60 seconds) and mistakes drain it, so a strong run lasts as long as you can keep the timer topped up.
What do I need to play Gemini Protocol?
A modern web browser. A desktop or laptop with keyboard and mouse works best; the game also runs on tablets and phones with touch controls.
Is Gemini Protocol the same as the dual-task paradigm?
Gemini Protocol is built on the dual-task paradigm, with some differences. Gemini Protocol turns that into two continuous tasks rather than two quick responses: one hand dodges obstacles on the left while the other collects orbs and avoids decoys on the right, and both draw on one shared timer. That makes it a training game built on the dual-task idea, not a replication of the lab procedure.
