DotBlu, formerly known as BluBet, lets people place fake bets on a variety of subjects ranging from entertainment to sports to technology to news and more. The key here is that BluBet involves no form of betting real money. Users can sign up for free and receive 30,000 BluBucks (which again have no actual monetary value), which they can use to place bets on a range of topics.

Other DotBlu rules: you get 1,000 BluBucks for every bet you create and if you lose all your BluBucks, the bust will appear on your record but you will automatically receive 10,000 more BluBucks. BluBet also offers polls and challenges as two different types of bets. Poll bet outcomes are determined by the most popular response, while challenge outcomes are based on the outcomes of a real-life event.
