If you have five minutes to spare and want a quick thrill, I highly suggest loading up the Australian ChickenRoad game. The rounds literally take seconds to complete, making it the perfect distraction for short breaks. The cartoon graphics are incredibly charming, but do not let that fool you; the gameplay can get incredibly intense as your multiplier climbs higher. Most reputable sites let you try out the action using free virtual credits first, which is perfect for getting a feel for how the different difficulty settings alter the path layout before risking real cash.
