Another Mastertronic 'flippy flippy' game, with the Spectrum and Amstrad versions on the same tape, is Reveal (24%). The object of the game is to memorise an onscreen isometric pattern. Then, when the screen is plunged into darkness, you have to manoeuvre your object, lighting up the blocks again (sounds like fun, doesn't it?) Once they are all fully lit you can move onto the next screen and repeat the process. This soon gets extremely tedious, especially when aliens decide to darken the blocks on the opposite side of the screen again (fume!). I doubt whether anyone would find Reveal worth even £1.99.
