Scam
This game is a scam to collect money, or economic rent without contributing anything to the market or society. The game is setup so that your expected winnings are less than your contribution, meanwhile the game extracts approx 15% of each pot. It is, at best, a game disguised as skilled betting but for entertainment which uses some simple techniques to guarantee extracting all of the money put in and never having to payout. This is the best scenario, at least then it wouldnt be fraud.
