About

Oubliette IIGS is Dan Henderson's dungeon puzzle, rewritten for the Apple IIgs by Walter Tengler and posted free on 4 November 2026. An oubliette is a cell with one way in, a trapdoor in the ceiling, and you have just come through it. Seven levels sit below that, each one screen of 11 by 9 cells. Nothing chases you and there is no clock. Skulls and trapdoors are what kill you, and you get as many tries as you want.

Henderson wrote the original in Applesoft BASIC. This version keeps those maps and rules, drawn in his new Super Hi-Res pictures, 320 by 200 and sixteen colors, from 28 by 22 pixel tiles. Tengler wrote the 65816 game, the Ensoniq sound effects, and the music for the title, the win, and the death. It needs a ROM 01 or ROM 03 IIgs with 512K. The disk is an 800K ProDOS image, volume OUBLIETTE.IIGS, and it boots itself.

Arrow keys or W A S D move one cell. On the title, Return or E starts, and Esc or Q quits to the ProDOS launcher. In a level, Esc goes back to the title. You pick up the chalice, use doors that send you somewhere else, and find keys for what is locked. Step on the exit and the next cell fades in. Die and the lose screen asks continue. Y retries that level and keeps the ones you already cleared. Clear the seventh cell and the win screen offers to throw you back in at level 1. There is no save. The player's manual in the download names what is new on each level. The download is free for noncommercial use under the 8-Bit Shack Noncommercial Source License, and the source is in their Free Games repository.
