Are you ready for Manic Rider? Practice does indeed make perfect and you’ll need it to complete the 10 extreme levels of this crazy, high-speed trial game. Each track is full of dangerous twists and turns, so you’ll need to try a good few times before successfully completing each one. But what makes the game tricky is that you only have 5 attempts at each level and mistakes are not tolerated. The most daring gamers out there can also try their hand at pulling tricks to increase their score.
