This year's theme for the event was "The Twisted Toybox" and was sponsored by Facebook, Videology, Astus UK, Active International and Verifone.
The charity, which aims to improve the wellbeing of everyone in advertising and media, thanked supporters for joining the party on 8 June.
"Whether you played our games, bid in our auctions, supported us through sponsorship or donations, bought a table, or partied on the dancefloor, thank you for helping to make last night a truly magnificent night," the charity said.
Next year's "Stranger Than Summer" event will be held on 7 June 2018.
