You are an adventurer on the remote island of Xaro. You only guide is a letter received from Dr. Chumley where it is said that he believed that the islanders had hidden a massive treasure somewhere on the island. Unfortunately Dr. Chumley did not live long enough to find the island's lost secret. Your quest is to find the treasure and escape alive.
In 2022, the game was unofficially ported to the ZX81 by Steve Dobbs of Mancave Software, using his MATE system; see here for details.

Pete Cooke's first foray into text adventures. Very coarse, BASIC only and limited by it, but I have seen (and done) worse for first attempts.
I have very fond memories of playing this in the early 80s. This was the first game I managed to solve without any hints. Quite a bit of trial and error involved in dealing with NPCs, but still very absorbing.
Another one of my first text adventures on the ZX Spectrum.
One of the more nostalgic games I played and remembered as i hired this for the week from a shop from my local town Willenhall in the West Midlands.
It's always stuck with me all these years and introduced me to his other game Urban Upstart which I completed.
Invincible Island is written in basic and a bit slow, the adventure isn't too hard and it's also your standard fare but it will always be remembered as one of those games that set me on a path to play more.
