Learn with Biffie
Who Biffie is, what fiber does, and how to play every game in the deck.
Who is Biffie?
Biffie's name is short for Bifidobacteria. Bifidobacteria is a type of bacteria, a tiny living thing, that lives inside your gut. Your gut is the long set of tubes that runs from your mouth all the way to your bottom.
Biffie and his trillions of friends are helpful bacteria. They help fight off bad gut invaders. So what should you feed Biffie? Fiber!
What is fiber?
Fiber is the part of plants your body can't break down well. Biffie and his friends love to eat it, and they turn it into gas.
So eat your plants and feed Biffie!
How much fiber do you need?
Grams of fiber per day, by age. One card of black beans (7 g) covers more than a third of what a 4 to 8 year old needs.

The 10 plants in the deck, from least to most fiber
There are 4 of each plant, plus 2 Biffie wild cards worth 15 points.
Four ways to play
Every game uses the same deck: 40 plant cards worth 1 to 10 grams of fiber, plus 2 Biffie cards.
Feed Biffie
- Deal 5 cards to each player. The rest go in a middle pile.
- On your turn, ask another player for a plant, like "Do you have any Bell Peppers?"
- If they have it, they hand it over. You can ask again, or ask a different player.
- If they don't have it, they say "Feed Biffie!" and you draw from the pile. If you draw the plant you asked for, you get another turn.
- Put down each set of 4 when you have it. When a player runs out of cards and the pile is empty, the game is over. Most sets wins.
Fiber War
- Split the deck so each player has 20 cards.
- Both players flip a card at the same time. The higher fiber card wins both, and they go face down on the bottom of the winner's stack.
- Same number of grams? It's a Fiber War! Each player adds 3 cards face down, then a 4th face up. The higher 4th card wins all 10 cards.
- Another tie is a Double Fiber War. Add 3 more face down and another face up. The higher card takes all 18.
- Keep playing until one player wins all the cards.
Add Biffie for extra fun: shuffle in the 2 Biffie cards. They beat every plant card, and each player starts with 21.
Secret Biffie
- Deal 6 cards to each player's hand plus 1 face-down secret card. The rest go face down in a middle stock pile.
- On your turn, draw from the stock pile or the discard pile. If it has more grams than a card in your hand, keep it and discard your lowest card.
- Keep playing until the stock pile is empty.
- Everyone reveals their secret card and adds up their points. Each gram of fiber is 1 point. Younger players can use the counting bars to add. Most points wins.
Add Biffie for extra points: the 2 Biffie cards are worth 15 points.
100 Grams
- Deal 5 cards to each player. The rest go face down in a stock pile. Turn the top card face up to start the discard pile.
- On your turn, take one card from the stock pile or the discard pile.
- Make a set of at least 3 of the same plant and place it down to score.
- Once you have a set down, you can add cards to other players' sets. Tap your card on their set, then place it next to your own set so your cards stay together for scoring.
- End your turn by discarding one card face up. If the stock pile runs out, flip the discard pile to make a new one.
- A round ends when a player plays all their cards and discards their last card face down. Everyone adds up their fiber grams. Play rounds until someone reaches 100 grams.
Add Biffie for extra fun: the Biffie cards are wild and worth 15 points.
