Betting servers need Self Betting to keep it from dying (as Devil stated)

If you want to self bet and someone else is in front. Use their SB to possibly get profit. If you bought a nudge, you'll get to play eventually since SB should be pretty high, more than nudge. They'll run out of TC eventually or grow bored from playing.

Ex: Nudge is 1k | SB to 1st is 5k (or higher)

Say the server is dying.

Ex: Nudge: 500 | SB to 1st is 3k (or higher).
