"Welcome to Spelunx!"

Spelunx is an educational game cleverly disguised as an exploration in a cave. Aimed primarily at grade school aged children, the cave contains many toys, games, and activities that are fun to play with but also happen to teach principles of math, biology, physics, etc.

As with the Manhole and Cosmic Osmo, each scene was hand drawn by Robyn Miller. Originally released in black & white for the Macintosh in 1991, Spelunx was colorized by Josh Staub (who still works at Cyan) and re-released in 1993.

Here is a brief peek into the world of Spelunx.

This door leads to a wondrous underground kingdom.

Sometimes it can be easy to get lost in the cave passages, (but it's possible to turn on a map if you're really lost.)

A doorway opens to Professor Spelunx's and Mr. Seudo's office.

Professor Spelunx's bookshelf

Mr. Seudo's telescope teaches Cartesian coordinates.

This little teapot contains an entire forest.

The Tree Gene-orator allows you to pick the traits of a tree, plant it, and watch it grow over time.

Yodel Toasters is one of the games you can play. When the yodeler drops a piece of bread, you must catch it with your toaster and launch it back up to him.

These are just a few examples. You can also study metabolism by changing the environment of a pet lizard, learn properties of light and sound with the lightning simulator, experiment with gravity by dropping pebbles in the Yon-Yon Caverns, watch the Criss-Ants as they search for food and take it back home, and many other activities. The cave system is also modular, so it is possible that if new rooms are discovered in the future, they can be added to your cave.

Unfortunately, Spelunx is currently unavailable. Professor Spelunx and Mr. Seudo are still continuing their explorations of Planet X and haven't returned yet. I hope they come back soon.
