Engine Explorersfree self-regulation game for kids 6–9Every engine has a speed. This game helps children find theirs.
Engine Explorers is a free browser game for children aged 6–9. Over five chapters it teaches them to notice how their body feels, name the speed their engine is running at, and choose a tool that changes it.

The problem it practises
Wound up and can't stop
Bouncing off the walls after school. Big feelings that arrive faster than words. The child isn't choosing this — their body is running hot and nobody has shown them the dial.
Foggy, flat, hard to start
This half is usually ignored, and it matters just as much. Engine Explorers practises waking a sluggish engine as deliberately as calming a revved one.
Naming comes first
A child who can say "my engine is running high" already has distance from the feeling. The whole first chapter is noticing and naming, before a single strategy is offered.
What a child actually plays
Engine School
Meet the Zoomies and learn the three speeds. Short scenes ask the child to gather clues from the body first — clenched hands, heavy legs — and only then name the speed.
Toolbox Workshop
Five hands-on stations, one per sensory channel: mouth, move, touch, look, listen. Each is a real mini-game, including a listening station with genuine synthesized rain, drums and music.
Breathing Peaks
Three paced breathing patterns the child breathes along with, then the Rumble Storm — a boss encounter whose weather visibly clears as they regulate.
Sleepy Swamp
The low-engine chapter. A rhythm game with real timing windows wakes the body up, leading to the Great Grey Fog.
Friendship Falls
Eight social scenarios where more than one tool is right. The child has to say why they picked a tool, so the ending can't be reached by guessing.
The Mixed-Up Carnival
Eight mixed rounds interleaving everything learned, a narrative reveal, and a printable certificate.
Built on frameworks, not vibes
The engine-speed metaphor comes from the Alert Program® framework (Williams & Shellenberger). This game is informed by that framework and is not affiliated with or endorsed by it. It also maps onto CASEL social-emotional learning competencies, uses simple body–brain–action links from CBT, and teaches paced breathing.
How it teaches matters as much as what: a teach → model → guided → independent gradient in chapter one, spaced-retrieval warm-ups opening later chapters, and two-part specific praise instead of generic "well done".

Designed to be kind
No dark patterns
No streaks to break, no notifications, no guilt copy, no timers pressuring a child who is already dysregulated. Milestones are cumulative and never go backwards.
Mistakes are coached
A wrong answer gets a gentle sound and a hint, then another try. Nothing is ever lost and progress is never taken away.
Playable by a non-reader
Turn on auto-read and every screen speaks itself aloud in order, highlighting the sentence being read. A six-year-old who can't yet read can play alone.
Accessible by default
Large touch targets, a high-contrast mode, and a motion toggle that also honours the system reduced-motion setting. A Calm Corner is one tap from every screen.
Several children, one device
Engine Explorers holds up to four explorers, each with their own name, colour and completely separate progress. Children pick their own face to play — they never have a password.
A grown-up can optionally create one account for the household. That backs up every explorer's progress and lets a child carry on from a different device. It is entirely optional: without an account the game saves on the device and works offline exactly as before.

Common questions
Is it really free?
Yes. No cost, no in-app purchase, no advertising, no upsell. Nothing is behind a paywall.
What age is it for?
Written for 6–9 year olds. Younger children usually enjoy it with a grown-up reading along; older children working on regulation often still get value from the toolbox and breathing chapters.
Does my child need to be able to read?
No. Auto-read speaks every screen aloud in order and highlights the sentence it is reading.
Does it work on a tablet, and offline?
Yes to both. It runs in any modern browser, installs to the home screen, and once loaded it plays with no connection at all.
Is this therapy?
No. It is an educational game and does not replace advice or treatment from an occupational therapist, psychologist or doctor.
Do you collect data about my child?
The game itself has no tracking in it, and without an account nothing about a child leaves the device. The website uses privacy-friendly, cookieless visitor counts. Full detail on the privacy page.
