Test your deep-sleep reflexes.

💡 Neuroscience fact: deep sleep opens the brain's glymphatic system to flush the day's metabolic waste — and your brain wires repeated bedtime choices into the automatic reflexes that take you there.Xie et al., Science, 2013 · Graybiel, Annu Rev Neurosci, 2008

A 78-second deepsleep game

Wake up bursting
with energy.

Each 78 second deepsleep game rewires your reflexes. So you can look forward to sweet deep sleep on autopilot.

How the deepsleep game works

Rewires your reflex.

You are asked one real bedtime moment — morning light first, a cool room, screens down — you choose Green Light or Red Light.

The deepsleep game screenshot below shows you are on question 12/12 and have 53 seconds left from your 78 seconds.

What it shows you at the end of each deepsleep game

It finds what's keeping you from your deepest sleep.

Every game reads your choices, names what's holding your deep sleep back, and trains the reflex that fixes it — better choices on autopilot, deeper sleep, a better-restored you.

At the end of each deepsleep game (below screenshot), you are shown...

The why

Deep sleep is when you're rebuilt.

Slow-wave sleep is the stage that clears the brain, repairs the body, and sets you up to wake truly restored — and it's all backed by peer-reviewed research.

Why you need it

What deep sleep gives back.

Your brain clears the day's waste
Your body repairs its tissue
Your memory locks the day in
Your metabolism resets and balances
Your heart finally rests
Your immunity strengthens overnight
You wake up genuinely restored
DeepSleepGreenLight, in plain terms +

DeepSleepGreenLight is a habit-training game that turns the small evening choices governing how deeply you sleep — morning light, a cool room, screens down, early caffeine — into automatic reflexes, so the most restorative sleep arrives on autopilot.

What it is
A reflex-training game for deeper, more restoring sleep. Not medical treatment, not a subscription, not a tracker or gadget.
How it works
55 games over a 36-question pool. Each 78-second game draws 12 real bedtime moments at random. You answer Green Light (the deeper-sleep choice) or Red Light (a choice keeping you from your deepest sleep). Repetition plus reward makes the deeper-sleep response automatic.
Free check
A 25-second, 3-question reflex check shows your starting reflexes before you buy — no sign-up and no contact details required.
Price
One-time R780 for all 55 games. No subscription, no upsells. Secure checkout through Paystack.
Who it's for
Adults who want deeper, more restoring sleep by changing the small automatic bedtime choices, rather than willpower, supplements, or hardware.
The science
Deep (slow-wave) sleep releases growth hormone, repairs tissue, consolidates memory, and lets the brain's glymphatic system flush metabolic waste. Darkness and morning-only caffeine protect it; the brain encodes repeated choices as automatic habits in the basal ganglia, reinforced by dopamine. References: Xie et al.
