A 1991 edutainment curio from the pre-Myst Cyan, worth picking up if you want to hand a curious kid something genuinely clever, or scratch your own nostalgia itch, but don't go in expecting a game you can finish.

I'll be straight with you: Spelunx sits in a category that most modern storefronts don't have a shelf for. It's a first-person, point-and-click cave explorer built in 1991 by the brothers who would later make Myst, and it plays less like a game and more like a very imaginative toy box. You click around interconnected rooms, each hiding a self-contained activity, and nobody tells you what to do or where to go. There is no win state. There is no lose state. There is barely a story. If that sounds maddening, it will be. If that sounds freeing, you might genuinely enjoy yourself. What Cyan pulled off here is subtle. The activities scattered across the cave rooms teach real concepts without ever announcing that they're teaching anything. The Animation Machine walks you through stop-motion logic, Mr. Seudo's telescope deals in Cartesian coordinates, the Yon-Yon Caverns toy with gravity, and a Lightning Simulator demonstrates the speed-of-sound relationship between sight and sound. There's also a Pigtoad Tree that covers choreography and music, a Criss-Ants section about animal behaviour, and a genetics activity hiding in the Tree Gene-orator. None of these are labeled as lessons. You find them by clicking around, which is exactly how discovery is supposed to feel for an eight-year-old. The honest caveat is that this is a preservation port, not a remaster. The system requirements listed on Steam still reference Windows XP and Vista. The colorized 1993 version that shipped on Steam is a step up from the original monochrome HyperCard release, but the artwork is still hand-drawn, low-resolution, and unmistakably from another era. A hidden editor that existed in earlier versions, which let players rearrange and expand the caves, is gone entirely from the Steam build because the underlying HyperCard technology no longer exists. If you remembered that editor fondly, it won't be here. Players who picked this up expecting the version they had on six floppy disks report real disappointment on that front. The mixed Steam reviews land exactly where you'd expect for something this niche. Adults buying it cold, without nostalgia or a child to sit next to, often find it shallow and brief. Adults buying it as a memory trip find it smaller than they remembered but still charming. Parents buying it for younger kids report it holds attention reasonably well. The game is genuinely short by any modern measure, and there's no loop that brings you back after you've poked every room once. It's a snapshot of a specific moment in educational software history, made by people who were quietly prototyping the design language that would define Myst two years later. If you have a kid between roughly five and ten who likes clicking things and finding surprises, this is a good, low-pressure spend. If you're an adult chasing pure nostalgia, go in with calibrated expectations, because the middle floor and its editor are gone, and the magic is smaller than childhood made it seem. If you have no connection to early Cyan at all, there are better casual exploration games available today. Alex, Scout Team

GamerScout Verdict

Best for parents with young kids or die-hard Cyan historians; solo adults buying on nostalgia alone should temper expectations hard.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
