SuperLenny joins a few sites that know they have a weaker sportsbook and they are upgrading it. We don't know what their platform will be if they are changing service providers but can assume it will be better.
From our inbox:
Good news! This month SuperLenny’s Sportsbook is being upgraded to a new platform and will be faster and stronger than ever before! We will be asking players to use up any existing bonuses by 23:59 CET 18.11.16.
To ensure a smooth migration we will temporarily remove SportsBook welcome bonuses between the 18th and 23rd of November, and we anticipate 24 hours of downtime from 12:00 midday on 22nd of November.
You’ll find some awesome new features, including cash out on live 1X2 football bets and live statistics plus big improvements to mobile betting.
Thanks for your understanding and we look forward to sharing the new improved SuperLenny Sportsbook with you!
