Zuma Deluxe Demo from www.shockwave.com Reviewed by Sue Zuma is great fun! It's a very simple game but very addictive. I don't know who or what Zuma is, but it may be the little frog- like creature in the middle of the screen that you control. The playing area is a channel full of coloured marbles. Zuma (we'll call him that for the sake of argument) has one of these marbles in his mouth. You can swivel him using the mouse and fire the marble he holds. If it lands next to more marbles of the same colour to make a chain or three of more, they explode and vanish, scoring you points. The remaining marbles close up, and this may also bring more like coloured marbles into contact, setting off a chain reaction. You score more points for this. You also score extra if you explode a sequence of marble sets - this is called a Chain Bonus. Some marbles give you extra skills like accuracy, slowing down the marbles, or making them roll backwards. Yes, that's the crux of the game. Marbles are continuously entering from off the screen. They move along a track until they go through a sort of plug hole at the end. If that happens, you lose a life. There are two ways to play the game. 'Adventure' takes you through a series of increasingly difficult levels, with tortuous tracks. In some cases there are two tracks and plugholes! 'Gauntlet' pits you against one level that gets more difficult as you play. You start with four colour marbles - red, green, blue and yellow - but others gradually get added. I saw mauve, then a silver colour. Of course this makes it more and more difficult to get a set of three before you run out of time. Though Zuma holds one marble in his mouth, you can click the mouse to swap from this one to the next one. This may help considerably when you're trying to get a set and time is running out. After a while, when an orange bar on the screen fills up because you've scored enough points, no more marbles enter the screen. The word "Zuma!" is chanted at that point. You can breathe a sigh of relief because you know you only have to clear the ones that are there. It's really frustrating when you realise a marble is teetering on the edge and you're just about to lose the level. You really want just one more go. The demo lets you play for an hour. It goes WAY too quickly. The full game costs $19.95. - o -
