The idea, ignoring the flimsy storyline, is that Road to Vegas is a light-hearted collection of mini-games that range from proper casino fare such as Poker and Baccarat through to old arcade enemies of the wallet like one-armed bandits and tiny plastic horse racing. Naturally, for any game involving gambling, they've tied it in with the world's most famous gambling venue, Las Vegas, and so you have a menu screen that's captained by a lady in a skimpy dress, and all of the money is in dollars. This seems fair enough at first, until you start the game and discover yourself in, of all places, Blackpool.
However, the difficulty levels usually only affect the chance of winning, rather than the difficulty, which makes many of the games even more frustrating than they already are.
But these can't solve the larger problem; that many of the games on offer should be fun but end up being impossible to play, either through difficulty or boredom. What happens in Vegas, so they say, stays in Vegas. If only this game had, too.
tl;dr Bad game. As if there was any doubt.
