is a pretty interesting puzzler from Yamisoft Entertainment. The objective of the game is to feed your pet before your opponent does, by splicing genes and creating a creature which matches exactly the one they're thinking of.
Choose creatures from your stock to examine their DNA strands, then pick the traits you need to create the right meal for your pet by determining matching genes. The gameplay system is a little complicated but fortunately the tutorial offers proper guidance to get any player started in just a matter of minutes.
The difficulty can be adjusted from the options menu, plus the trial version is not time limited. Don't be fooled by the graphics, even for grown-ups the game can be quite challenging.
