Racing and puzzle games aren't the likeliest of bedfellows, but in Trials HD the two get up close and personal to deliver a unique experience that is well worth the asking price. On the surface, this is an extreme motorbike racing game set in an abandoned warehouse, full of twisted metal girders, explosives and 100-foot drops, all of which are just right for putting your rider through the grinder and seeing them smashed into a pulp. But look a little closer and you will start to see the underlying puzzle elements amid this orgy of destruction and pain.
