4 Quality Little Game...twisby | 29/08/2007 | See all twisby's reviews (4)Zoo Keeper is one of those incredibly simple games that really get under your skin. The concept couldnt be more simple, line up three of the same animal to 'catch' them and wipe them off the screen. Think of it as a cross between Tetris and Connect 4! Thats about it, but it really does get addictive and you can lose plenty of time playing it! It does have some annoying points, such as the music and sound effects and dont expect a lot of variety! The different play modes are dressed up versions of the basic game, but that doesnt matter too much because its the simplicity that will get you hooked!
