Turn structure (continuous play)
Nucleum has no fixed rounds. Players alternate taking single turns; on your turn you either play an action tile or Recharge.
Play proceeds one player at a time with no discrete rounds or phases. On your turn you take exactly one of two options: play an action tile from your pool into the leftmost free slot on your player board (then resolve one or both of its actions), or Recharge to reclaim your played tiles and take income. You keep taking turns until the game-end condition is met.
Examples
Scenario. You have no action tiles you want to play, or your slots are full.
Resolution. Take the Recharge action instead of playing a tile.
Resolution. Take the Recharge action instead of playing a tile.
Common mistakes
- Waiting for other players to 'finish a round' — there are no rounds.
- Forgetting you may resolve one OR both actions on a played tile.
