1983 Sinclair Research (UK)
by Victor Serebriakoff
An excelent 1983 IQ test written in BASIC. You complete the test within an hour and a half or so, and answer several types of intricate questions raging from grammar, maths, space and shape, etc.
The answering is a bit slow but the game is well written and well prepared making it an enjoyable experience.
I would love to have had this as a kid.
By the way I scored 127 IQ which means an 86th percentile, but thats not acurate to todays standards. Still it sounds pretty good!
