I thought this was a great game, untill I discovered that even if 'your' magnet wins, you can lose money. See for example http://coinmagnets.com/round/63 - For the top 9 of the blue magnet payments, the payout is smaller than the investment...
Yes, round #63 wasn't so good. Payments on red were very low and payments on blue came to late so the fee was significant enough to eat up all profit for some players on the blue side.
I will increase bonus amount. This will hopefully prevent situations like this one from happening
