Celt, Latin Celta, plural Celtae, were an early Indo-European people who from the 2nd millennium BCE to the 1st century BCE spread over much of Europe. Their tribes and groups eventually ranged from the British Isles and Portugal to as far east as Transylvania, the Black Sea coasts, and Galatia in Anatolia and were in part absorbed into the Roman Empire as Britons, Gauls, Boii, Galatians, Celtiberians, and Lusitans. Celtae is a "worker swapping" game powered by a "rondel" where players choose actions to perform during their turn. On their turn, players will swap one of their 3 active workers with one of the 3 workers on the action space they wish to perform. Then, they perform the action which will be boosted if they have, on their pool of workers, specific types of workers: Farmers, Builders, Soldiers, and Nobles. The Farming action will allow players to draw cards and it's boosted by farmers. Cards have 3 types of uses in the game: they can be used to build, prepare for battle, or to engage with the Druid order. The Build action will allow players to build and expand Citadels on the board by placing their discs on them and it's boosted by Builders. At the end of the game, only completed Citadels will score, so players will have to work together to complete them and, like that, be able to score their presence on them. The Battle action will allow players to defeat increasingly stronger Roman armies and to Garrison the outskirts of the Citadels on the map, and it's boosted by Soldiers. The Recruit Action will allow players to recruit workers to their tribe, increasing the number of available workers to boost future actions, and it's boosted by Nobles. However, if you manage to send certain types of workers from your tribe into the Druid Order, you'll get their favor and a Druid worker who functions like a joker and boosts almost every type of action. Each time players engage with the Druid order, Battle a Roman Army, or Build in a Citadel, they will gain a bonus that was randomly assigned during setup. The combination of these bonuses with a timely performed action will often result in powerful combos. Every player has also a leader card, assigned to their tribe at the beginning of the game. During the game, if the player meets the requirements of their Leader they can decide to leave it like that and gain a small number of points at the end of the game OR forfeit those meager points and flip it to its Heroic Side which has much harder requirements at the end of the game but also gives the player a bigger amount of points. Each time the action marker on the rondel completes a full turn, the player who currently holds the favor of Teutates will place a progress marker in one of the progress cards next to the game board. At the end of the game, only progress cards with progress markers will score. So, as the game advances, players will be deciding what will score and what will not score at the end of the game. —description from the publisher
