99Things is a small find-a-thing game where you look for things in puzzle squares and try to complete the puzzle as quickly as possible (or not!).

While it targets MS-DOS based computers from the 1980s it can run in DOSBox too!
It is released as Public Domain / Open Source and was written in Quickbasic 4.5

There are different modes you can play 99Things in:

QuickGame - designed around a single, smaller board with less things to find.
99Things - play on 1 to 4 boards of 99 squares in size (see screenshot).

With these modes you can choose to play a timed game, or a relaxing untimed game.
You can choose to clear things when you find them - to reduce the difficulty.

There is also an untimed custom mode where you can tweak the settings to your liking.

System Requirements

99Things was designed to run on an IBM-PC or PC/XT but should run on newer PC's too

At a minimum: 8088 CPU at 4.77mhz or higher, 256KB RAM, CGA Graphics (320x200x4 colors), 200KB Floppy or Hard Disk Space

Recommended: 8088 or V20 CPU at 10mhz or higher, 512KB RAM, EGA Graphics, Mouse, Adlib Sound Card

You can run this in an emulator too if you prefer - DOSBox should be fine just set the cycles to match a 386SX or else the sound might be choppy.

Note: The game only runs in CGA mode. EGA Graphics will give you custom 4-color palettes!
