Don't play the tournaments or challenges like the electric wheel or the payback magnet. Don't play challenges with high minimum bets to qualify to play. Those combination are all guaranteed to lose. The server with the random number generator is statistically set for you to lose way more often than win. It's all statistics, not all that complicated of a field of mathematics. The good part is that it's mostly fun, and they give you about 20 million of free chips a day at their Facebook page.
