I don`t interest in random games. It is situation, when you can`t change the result, you can`t have any win strategy. I use it only when i want to rest, in such situation i "pay for a ticket" - i know that i lose my money like visit on the football match, buying beer, etc. We know that we spend money, but we still pay.
Sport betting or poker is a chance to win money with your brains - you can analyze teams/cards and try to predict the result. Even if i lose i will feel myself nice, because i tried to increase my win chances.

As the result - i don`t care about money in random games - they were made for fun and i pay for fun. But i don`t see any reason to make big bets here.
