Things to play with
Small browser experiments: physics, cellular automata, falling blocks, a maze in the dark, an arena shooter through six ages of history, and a pencil company with Fortune 500 ambitions. Most are a single canvas and a tight render loop; one is an economy that runs for days. No installs, no accounts, no server doing the work. Pick one.
Orbital
Slingshot a probe through gravity wells.
A drag-to-launch physics puzzle. Planets bend your trajectory with real inverse-square gravity, so every shot is a small orbital-mechanics problem. Every level is built around a proven route that sweeps all three stars and lands in the goal.
- Canvas 2D
- Fixed-step integration
- Solution-first generation
Grains
A falling-sand sandbox with secrets in it.
Paint fourteen elements onto a cellular-automaton grid and let the rules fight it out. Lava glazes sand into glass, oil carries fire across water, acid eats through everything but one thing. Seventeen reactions are hidden in the rule set; the log fills in as you find them.

- ImageData
- Discovery log
Stack
Falling blocks, done properly.
The falling-blocks game you already know, built to the modern rulebook: seven-bag randomiser, hold queue, ghost piece, wall kicks and a lock delay you can play against. Clean lines, one colour family, no filler.
- Canvas 2D
- SRS rotation
- 7-bag randomiser
Upstream
Get a rubber duck from the sewer to the bath.
A maze you play in the dark. One rubber duck, one bathtub, and a tangle of sewer pipes between them, lit only by the small glow around the duck. Quack to light up the pipes around you for a moment, read the current, and find your way up to bath time.
- Canvas 2D
- Growing-tree mazes
- Fog of war
Arms Race
From a thrown rock to a laser, one round at a time.
A round-based arena shooter through six ages of history. You start with a rock. The horde grows every round, history moves on every three and marches in a new enemy, and the coins they drop are all that stand between you and extinction. Evolve fast enough and the laser is yours.
- Canvas 2D
- Wave director
- Swept collisions
Lead Time
Turn one pencil into a Fortune 500 company.
An idle economy game about the long road from a garage to the top of the Fortune 500. Buy cedar and graphite as prices swing, price against demand, hire crews, buy machines, and fund a lab whose ideas carry you from pencils to pens, notebooks, staplers and standing desks.
