Happy Bee is the fourth game in Helvetiq's "Fun by Nature" eco-friendly collection.
Each round, all players select their bee card(s) at the same time, then place them face down on the table in front of them. (The number of cards chosen varies with the round.) Once the cards are revealed, players check the majority for each family and collect flower cards, which are worth points.
When all the flower cards are distributed or discarded, pass the non-selected bee cards (which are still face down) to your left neighbor. Take the bee cards from your right neighbor and add the bee cards you just selected for this round to your hand. You should have seven bee cards again and can now play a new round.
The game ends after the ninth round. You add all the points of the flower cards you collected during the game, and whoever has the most points wins.
