If you keep up with the DS import scene, you might recall Nintendo releasing a puzzle game about nine months ago called Magnetica. Well, this is the same game under a different name - more in line with Mitchell's original PuzzLoop arcade game from 1998. Of course, if you've frequented the Xbox Live Arcade, you'll probably take one look at Actionloop and assume that this is a rip-off of PopCap's Zuma, but this is the real deal.
The gem-busting premise is largely the same as ever (i.e. heavily influenced by Bust-A-Move), but with a few interesting tweaks that, arguably, make the DS the best version of this hugely addictive puzzler. As ever, the idea is to make sure a spiralling line (or lines) of coloured gemstones doesn't reach the hole it's snaking toward. To do this, you have to continually flick gemstones from one or more launch pad(s) at the spiralling menace coming towards you - with three of a kind required to eliminate them.
The trick is to not only be quick and accurate, but to take advantage of The Rules of Attraction. If, for example, you match three reds and there are two yellow gems on either side, they will be attracted to one another, ensuring the line is dragged back a notch - helping to give you vital breathing space as you busily flick gems towards their target.
