TG4 is set to air an Irish language version of new Welsh language game show Y Deis (The Dice) in what is being called "a landmark content partnership".
The new show from Welsh station SC4 is about to begin filming in Cardiff and it will see three teams compete in what has been billed as "a unique blend of general knowledge, skill, strategy - and a little bit of luck".
The Welsh language version will be shot first at Cardiff's Enfys Studios, followed closely by an Irish-language version titled An Deis, hosted by journalist and presenter Eibhlín Ní Chonghaile and also filmed at the same studios.
An English language version will also be filmed for international interest.
During filming, a director from Wales will be shadowed by an Irish language director, who will gain additional experience in multi-camera studio direction.
According to TG4, three teams of two "go head-to-head across several rounds, building their prize pot through quick thinking and smart play. Only one team makes it to the final, where they face a high-stakes quiz against the clock to claim the Jackpot".
Presented by BBC Radio Wales breakfast host James Williams, Y Deis marks his debut on an entertainment programme for S4C. The Irish version will be produced by Tyrone Productions, who previously brought the Who Wants to be a Millionaire format to Ireland.
The centrepiece of the show is the dice machine , with die (the "deis") playing a pivotal role in shaping the outcome.
Laura Ní Cheallaigh, TG4 Commissioning Editor says: "We're delighted to bring this fresh and entertaining new format to TG4 audiences.
"Developing and supporting original content in the Celtic languages is a key priority for us, and this collaboration with S4C is a great example of creative partnership in action. We immediately saw the potential in this format and look forward to introducing An Deis to Irish audiences in Spring 2026 on TG4."
S4C’s Chief Content Officer, Llion Iwan, welcomed the collaboration: "This partnership with TG4 is another proud milestone for S4C and for Welsh-language content as a whole.
"It demonstrates that distinctive, homegrown formats have real power to travel - and we’re thrilled to see this show find a new audience in Ireland through our friends at TG4."
