Speculation

Gabriel also had Hi-Q games published with a "Hi-Q" in the same color scheme, and very similar font face. Also, a game called Take 5 was published by Gabriel with a slightly different "Hi-Q" logo.
Did one company buy the other? Was there some sort of agreement for both companies to have Hi-Q games? Was there some copyright infringement?

Here are some of Gabriel's Hi-Q games:

1977 Take 5
1978 Catch 21
1979 Point-Blank
19?? Over-n-Out

Take 5

Catch 21

Point-Blank

Over-n-Out

Break Away

Clues

All the Gabriel Hi-Q games listed above were published before the Ideal Hi-Q games, except possibly for Break Away.
Here are two different printings of Break Away:

Gabriel

Ideal

...so perhaps Hi-Q went from Gabriel to Ideal, through whatever transformation or transfer of ownership!
