We are delighted to announce that in October 2021, we will be publishing Brian Boru: High King of Ireland by award-winning designer Peer Sylvester (The King is Dead, The Lost Expedition).

Brian Boru

Featuring stunning illustrations from Deirdre de Barra, Brian Boru is a cutthroat game of power-brokering and intrigue in  11-century Ireland, in which players must strive to unite the provinces, securing control through whatever means necessary, to ultimately claim the title of High King of all Ireland.

According to game designer Peer Sylvester, “The success of the historical Brian Boru rested on three pillars: his victories against the Vikings, the favour he managed to garner with the Church, and the alliances he forged through political marriages. This became the foundation of the game, with each pillar becoming a suit in the trick-taking that forms the core of the mechanics. Win a trick and you gain influence in a town, which, in turn, gain you majorities in the regions – if you lose the trick, however (deliberately or otherwise), you instead take an action corresponding to the suit of the card

Senior Game Developer Filip Hartelius added that, “With Brian Boru, Peer has once again crafted a game where a simple core mechanic gives way to a real depth of play. You won’t just find yourself asking whether or not you want to win the trick being played, but which card you want to do it with. What you are trying to achieve is constantly changing to adapt to the other players, whether that’s through ever-increasing bids to court a prince for political marriage, or carefully making sure you’ve repelled just enough Vikings that they raid your opponents’ towns instead of your own. This game is a real treat.”


Ireland is awash with would-be kings, power-hungry pretenders, and self-professed rulers. The provinces are in disarray and the common folk are paying the price. The land needs a leader.

In Brian Boru, you will strive to unite Ireland under your domain, securing control through might, cunning, and matrimony. Join forces to fend off Viking invaders, build monasteries to extend your influence, and gather support in towns and villages throughout the land. To become High King of all Ireland, you will need to navigate a web of shifting alliances, outmanoeuvre your enemies, and grab history by the reins.
