Splatalot! was a medieval-themed physical game show which premiered in Canada on YTV on 14 March 2011, hosted by Jason Agnew and Matt Chin. It premiered in the United Kingdom on CBBC on 13 June 2011 with Dick and Dom as hosts and in Australia on ABC3 on 5 November 2011 with Kayne Tremills and Scott Tweedie as hosts. The series was inspired by the game show Wipeout, designed for a younger demographic. The British and Australian broadcasts of the show used the same filmed footage as the original Canadian, but with local presenters providing commentary.

Splatalot! was produced by Marblemedia and commissioned as an international co-production by YTV, CBBC and ABC3. It featured a large, extreme obstacle course and three rounds of competition: Cross the Moat, Ditch the Dungeon (Escape the Stockade in the first series), and Capture the Crown. Each episode featured a different group of 12 teenage contestants (known as Attackers) competing against not only the obstacles and the clock but also the Defenders. The Defenders are an international squad of nine medieval-themed gladiators, who are tasked with protecting the castle from the Attackers. The winning Attacker is crowned King or Queen of Splatalot!. This king or queen was able to then choose a defender to punish in one of many ways, such as throwing them into the water with a catapult.
