JupiterSportsbook (SBR rating D-) is a sister book to Bet33 (SBR rating D-). Although the Bet33 brands have not failed to pay a player since their inception, they maintain low ratings due to the fact they were founded with capital derived from defunct sportsbook Apex Sports (SBR rating F) which closed doors while owing many players. Apex insisted at the time that they were insolvent.
From SBR's 11/19 report on Apex Sportsbook paying a player after five years:
Apex ownership was adamant at the time it closed its doors that they were not solvent. bet33 management assures SBR that bet33 and sister sportsbooks
are well funded and it will repay players who had Apex Sportsbook balances at the time the sportsbook flat-lined. Apex victims are asked to write to Help@SportsbookReview.com
so we may help in arranging payment."
