Well, it sounds like the payout will continue to rise every hundred wins, or so. However, even if they give 10K for win number x, it still won't be worth it. It's my opinion that they need to give a payout every ten wins to make it worth it - assuming that payout is at least a few thousand credits.
It takes so long to win 100 games, much longer than getting that same payout in one of the other mini-games...
