About Celtic Clash

The Celtic Clash deck brings legendary Heroes, supernatural Creatures and powerful Relics together in a fast card battle.

But the names and stories on the cards come from a much larger tradition.

The Celtic Clash Companion was created to take players beyond the cards — revealing more of the mythology, folklore and real Irish places connected with the world that inspired the game.

Use the Companion to explore every card in the base deck, discover extended stories, learn how to play and visit real places across Ireland associated with the legends.

Where mythology, folklore and archaeology overlap, the Companion aims to make the distinction clear — celebrating the stories without presenting legend as historical fact.

From Emain Macha and Rathcroghan to the Hill of Uisneach, Tory Island and the landscapes of the Fianna traditions, many Celtic Clash stories remain connected with places that can still be explored today.

The Explore Ireland section brings those connections together while recognising the difference between archaeology, medieval literature and later folklore.

Celtic Clash is first and foremost a physical card game.

The Companion is designed to enhance the deck rather than replace it — giving players rules, stories and places to explore while keeping the battle itself on the table.

Celtic Clash began with a simple idea: to create a game that brought the heroes, creatures, relics and stories of Irish mythology to the table in a way that was exciting, accessible and unmistakably Irish.

What started as an idea grew into a physical card game, and from there into something much bigger — with its own Companion, extended lore, real places to explore and an ever-growing world around the game.

Celtic Clash was created and published in Northern Ireland by Coco Games.

Game concept, development, rules, research and creative direction.

The visual world of Celtic Clash was developed using a combination of creative direction, graphic design and AI-assisted image generation.

The cards, packaging and supporting materials were developed through an iterative design and production process, with each element shaped specifically for the world and identity of Celtic Clash.

Special thanks to Najib for his work helping develop and prepare the game's production artwork and packaging.

Celtic Clash was shaped through real games, feedback and plenty of testing before reaching its final form.

Special thanks to Board Game Café Belfast and Antrim Card Club for helping playtest Celtic Clash. Your time, feedback and willingness to put the game through its paces helped refine the rules and improve the experience at the table.

A special thank you to Roy, for backing Celtic Clash and believing in what I was trying to create from the early stages.

And to Clare — for listening to every idea, every problem, every change of plan and, perhaps most importantly, listening to me stress about all of it. Thank you for putting up with the journey from an idea to an actual game.

A very special thank you to my mum and dad, who travelled with me to explore many of the real places connected with the mythology and folklore of this island.

Those journeys helped Celtic Clash become about more than the stories themselves. Seeing the landscapes, monuments and places associated with the legends helped inspire the connection between the physical game, the Companion and the real Ireland that players can explore for themselves.

Special thanks to Gaelcon for giving Celtic Clash the opportunity to officially launch at Gaelcon 2026 in Dublin.

For an independent game taking its first steps into the world, having the opportunity to launch among Ireland's gaming community is something we're extremely grateful for.

Celtic Clash draws inspiration from Ireland's extraordinary mythology, folklore, medieval literature and storytelling traditions.

From Cú Chulainn and Queen Medb to Fionn mac Cumhaill, the Morrígan and the Tuatha Dé Danann, these stories existed for centuries before Celtic Clash and belong to a much larger cultural tradition.

The aim of Celtic Clash is not just to bring these legends to the table, but to encourage players to discover the stories, people and real places behind them for themselves.

Thank you to everyone who has supported Celtic Clash while it was still just an idea, and to everyone who picks up a deck, plays a game and becomes part of what comes next.
