Players must always keep an eye on the timer.
When the 1-minute timer runs out, the round is over and the game pauses. If the current player has already drawn a tile, then they must first finish their action as usual.
Then, the current player rolls both of the Giant Wave dice and removes all of the tiles from the rows that match the number and color of the dice by discarding them face-up.
Giant Waves do not remove a tile with a Bird token on it. If a tile with a Bird token is about to be removed, remove the Bird token instead. However, if the tile with a Bird token is targeted by both Giant Wave dice (at the intersection of the rolls), both the Bird token and the tile are removed.
Once the tiles are removed and discarded face up, restart the timer and start a new round.
The turn passes over to the next player in clockwise order.
