Dead Mountaineer's Hotel is an adventure game based on the sci-fi detective novel of the same name (1970), also known as Inspector Glebsky's Puzzle, by the Soviet Russian authors Arkadi and Boris Strugatsky. The player takes the role of inspector Peter Glebsky, who just wants to have a nice holiday in an isolated mountain hotel, but is eventually compelled to solve a mystery about a vanished mountaineer who supposedly haunts the hotel.
The whole game is set in said hotel. The gameplay offers the usual adventure gameplay: the player explores the hotel, takes items, talks to the other guests and solves item based puzzles. There are also a few (mostly optional) mini games, e.g. darts, pool or action sequences, and logic puzzles, e.g. the player has to choose his dinner components so that no one of the other guests makes fun of him. Some sequences are in real-time, meaning that the player has to wait for next script to happen. The game uses the established one-click controls.
