Basically a chain match game with differences: your chain can go in any direction, and as well as matching the same creatures there are levels where you make a food chain, e.g. jaguar to bird to fruit, eagle to rabbit to grass, etc. Also a gold box covering two squares keeps appearing and you have to manoeuvre two of the same creature into it. Various things happen to lock tiles, and bonuses to free them need to be dropped off the bottom of the board. Even in the first levels I struggled to get enough bonuses before too many squares were locked. Perhaps it gets easier with practise but I gave up before the trial hour was over and I doubt I will be buying this game - a shame because it has the most original and interesting ideas I've seen for some time.
