Part of a series of unreleased games and programs by Channel 8 Software, ‘Gotcha’ Maths was one in a line of educational software releases (or as it is now, planned releases).
As we have no idea of the content of the software, we can only presume it must have differed in format to Primary Maths and the released game, Maths Tutor, in some way.
As with all the rest we have no idea of why these games went unreleased, though for more posturing check the entry for Toddler Tutor!
Thanks to contributor Sean O’Neill, it has been confirmed that the game had a limited release and can be found here on Retro Collector. However, the game has yet to be preserved, so we hope that it will be soon and the case can be closed on this game, now known to have been released.
