Games you can play, and the honest state of the rest.

This one is not mine. My son Jacob made it when he was nine: his idea, his game. I talked him through the instructions, and he did the fixing himself. It is a browser mini golf challenge in HTML5 canvas and vanilla JavaScript - click or drag to aim, then release to shoot.

Engine

HTML5 Canvas and vanilla JavaScript

Input

Mouse or touch

On a phone

The live build is a canvas game that accepts click or drag aim.

This one is Jacob's as well. My son made it when he was nine: his idea, his game, and his own fixes once I had talked him through the instructions. It is a canvas football match - one player against the AI, or two players sharing one keyboard. An online mode ships with it too, but the Socket.IO server it dials no longer answers, so the local modes are the ones to rely on.

Engine

Canvas 2D, with Socket.IO behind the online mode

Input

Keyboard, with on-screen touch controls

On a phone

Touch controls are built in; two players on one keyboard needs a desktop.

A Flutter and Flame classroom game: answer the arithmetic faster than the other side and pull the rope your way. Built for a browser and meant for a shared screen.

Engine

Flutter and Flame

Input

Touch or tap keypad

On a phone

Runs in any browser; the Flutter payload is still a few megabytes on a phone connection.

Built size

774 KB transferred from the live host, 2.6 MB decoded, plus the CanvasKit renderer the page pulls from a Google CDN

A three-dimensional scene you play with your hands: MediaPipe reads the webcam and your grasp flicks cake to the crying baby, and a drag-and-flick mode carries machines without a camera. It is by far the heaviest thing here, so open it on a connection that can take it.

Engine

Vite, Three.js and MediaPipe Hands

Input

Webcam hand tracking, with mouse and touch

On a phone

Needs HTTPS and camera permission, and it is a 33 MB download - unkind to a phone connection.

Built size

32.7 MB transferred from the live host, of which one 29.5 MB model file is nearly all of it, plus MediaPipe from a CDN

MediaPipe tracks facial landmarks and turns them into flight input, so the drone answers your expression rather than a controller. It flies forward on its own; you steer it through the diamonds and past the enemies with your face.

Engine

Astro, React Three Fiber and MediaPipe Face

Input

Webcam face tracking

On a phone

Written with a phone camera in mind; needs HTTPS and camera permission.

Built size

201 KB transferred to open the page, then about 10 MB once you press start - almost all of it the MediaPipe face model

A drawing canvas for children: pick a colour, a brush size, and a tool, sketch an outline, then press Generate 3D and the result lands in the gallery beside the canvas. The live build carries its own back end, so a doodle is stored rather than lost on refresh.

Engine

Vite and React, with an Express, Drizzle and Postgres back end

Input

Mouse or touch drawing

On a phone

A mobile drawing layout ships with it.

This was an idea project: a prototype made to test whether the concept held up, not a finished game. Pick a character, describe the world you want, and build it from one of six templates: blocky caves, sky defence, racing, retro arcade, ocean, or galaxy. The simplified build runs entirely in your browser with no account and no network calls.

Engine

HTML5 Canvas

Input

Mouse or touch

On a phone

Works on phones; the template grid is easier to read on a larger screen.

Built size

74 KB, single self-contained file

A reaction-timing game written in C for a microcontroller, with physical buttons and lights. It is a real, finished game; it simply does not live in a browser.

Engine

C on a microcontroller

Input

Physical buttons

On a phone

Not applicable - this one runs on a circuit board.

Built size

0.8 MB source

It runs on hardware, not in a browser. The repository is the honest record.

Carlos's own implementation from a course where the teacher supplied an example. The code is his; it is a desktop Java application, so it is listed here rather than embedded.

Engine

Java on the desktop

Input

Keyboard

On a phone

Not applicable - desktop Java.

Built size

1.8 MB source

Desktop Java does not run in a browser. Excluded for shape, not for authorship.
