I see for Multi Bet Jackpot Leaderboard for October.
This mean for parlay? Then rank is based we have a big payout accumulation with amount price win? or this rank based muliple?
Yes multi bet is the term for parlay on sportsbet. For your 2nd question their leaderboard starts with the highest potential win from a user's multi bet so the higher you bet the more chance of getting a high rank in the leaderboard.
