I played a considerable amount of skillz games in 2014. This "method" does will NOT work and you are all wasting your time and money if you attempt it. On all matches, skillz takes 16.67% of the entry fee as their cut. This means you will need to win 66.67% of your games to be profitable. This is especially problematic because the matchmaking system in skillz is not random. From their FAQ:
Essentially, their system keeps placing you against opponents of incrementing skill until your win percentage settles at around 50%... And that's where the problem lies. If your win percentage is 50%, you are losing 16.67% of all money that you put in. Because of this, it is actually impossible to be profitable long term on skillz, let alone to the degree that OP has described.
Even best case scenario... Let's say you're the greatest player in the world, capable of beating everyone else 100% of the time. You will still not be able to make money on skillz! Remember what the FAQ said? "We would rather refund your money than pair you with someone whose skill level is not a match." The system will NOT match you against an opponent, ever, because there is no one else in your skill bracket. I personally ran into this issue back when I played. My win percentage was >90% and one day I just stopped getting matched against people. My matches would sit in "pending" for days and then I'd receive a refund.
The other "benefits" OP described are basically worthless too. Regarding ticketz, you get about 83 ticketz per dollar put in. A $25 target gift card costs 470,000 tickets. That means you have to put $5662 into the system, with an expected long term loss of $943, to get a $25 gift card. A "ticket multiplier" system exists within the game, but it never gets high enough to matter. Brackets are no good either. Similar to ticketz, to reap any benefit from them, you have to put in way more money than you could ever hope to win back. Bonus cash (if you have it) decreases the aforementioned 16.67% loss by a bit, but not nearly enough. It just makes you lose less money.
TLDR: OP is likely a paid shill for this company, it is impossible to be long term profitable on skillz. Go find something else to do.
