Biblios — Rules, Auctions, Scoring & Strategy
Build the richest medieval library by collecting manuscript categories, shaping the value of five dice and bidding wisely for cards.
Biblios combines card allocation, auctions and majority scoring in a compact game themed around the production of a prestigious medieval library. Five dice track the changing victory-point values of different book-making categories.
This guide explains player-count setup, the Gift phase, Gold and non-Gold auctions, Church cards, category scoring, tie-breakers and strategy.
The central Biblios decision
Every gift you keep and every card you auction changes the supply available to everyone else. The best library isn’t built from the most cards; it comes from winning the right majorities at the right die values.

1. Allocate
Keep a card, offer public choices and save one for auction.
2. Bid
Compete for cards placed in the Auction pile.

Use Church cards to alter category dice.
4. Score
Each category winner takes its die’s points.
Setup for two, three or four players
Biblios is a 2–4-player card-drafting and auction game designed by Steve Finn. The set contains an 87-card deck, a Scriptorium category-value board and five dice. Place one die on each category on the Scriptorium, initially showing 3 victory points.
| Players | Remove first | Then remove at random | Cards allocated per Gift turn |
|---|---|---|---|
| 2 | 6 Gold (two of each value) | 21 cards | 3 |
| 3 | 3 Gold (one of each value) | 12 cards | 4 |
| 4 | None | 7 cards | 5 |
Shuffle the remaining cards into a facedown draw pile. The unknown removed cards can include church, category or gold cards. Keep a separate facedown area for the cards that will enter the Auction phase.
How Biblios categories score
The five categories are Pigments, Holy Books, Monks, Manuscripts and Forbidden Tomes. Each category has its own colored cards and corresponding die on the Scriptorium.
Your card values in a category are influence for majority comparison, not direct victory points. At the end of the game, the player with the highest total card value in that category wins all the points on that category’s die. A die can change from its initial value of 3 during the game because of church-card effects.
Example: if your Manuscripts total is 8 and everyone else’s is 7 or less, you receive the entire Manuscripts die. If that die shows 5, you gain five victory points, not eight.
Gift phase: allocate cards without revealing everything
On your turn in the Gift phase, draw cards one at a time and allocate each immediately to one of three places: one card facedown for yourself, one facedown in the Auction pile, and the rest face up in the public space.
With two players you allocate three cards in total; with three, four cards; and with four, five cards. Exactly one goes to your private reserve and exactly one to the Auction pile. Every remaining card becomes public.
After allocation, add your reserved card to your hand. Starting with the player on your left, each opponent chooses one public card to add to their hand. Your turn then ends. You cannot change earlier allocations after seeing later draws.
Worked example: in a three-player game, you allocate four cards: one useful Monk for yourself, one Gold to the auction pile and two face-up options for the other players. Your left-hand opponent picks first, then the remaining player takes the other.
Auction phase: selling the secret pile
When the Gift deck is exhausted and all public cards have been chosen, shuffle the facedown Auction pile. The original starting player begins the Auction phase. Each turn, flip the top auction card face up and offer it to the table.
The player to the auctioneer’s left bids first or passes. Bidding continues clockwise; every new bid must be higher than the current bid. A player who passes cannot rejoin that particular auction. If everyone passes without a bid, discard the card.
The winner must pay the offered price and adds the card to their hand. If they cannot pay, the rules impose a penalty: each other player randomly takes one card from their reserve, then the auction repeats without that player. This makes bidding beyond your actual ability dangerous.
Buying category cards with Gold
When a non-Gold card is auctioned—whether a category card or a Church card—players bid an amount of Gold. The winning bidder discards Gold cards from their hand totaling at least the bid.
Overpaying is permitted and sometimes unavoidable. Example: you bid 4 Gold but have only a Gold-2 and Gold-3 card. You may pay both, losing five Gold cards’ worth of purchasing power to cover the bid of four; you do not receive change.
The discarded Gold is unavailable for the remainder of the game. Gold cards also matter for final tie resolution, so spending them has an opportunity cost beyond the immediate auction.
Buying Gold cards with other cards
Gold-card auctions follow a completely different rule: bids are in numbers of cards, not amounts of Gold. The high bidder discards exactly that many cards of any types from their hand, facedown, to acquire the auctioned Gold card.
Example: if the auction reveals Gold-3, you might bid two cards. If you win, choose any two cards from your hand to discard and add Gold-3 to your hand. The values printed on your discarded cards do not determine the bid.
This means a weak card can still have a valuable purpose in an auction, and a Gold-3 is not automatically worth three ordinary cards in all situations.
Church cards and Scriptorium dice
When a player acquires a Church card in either phase, the game pauses. The player may immediately use its power to adjust one or two category dice, or may decline the effect. The Church card is then discarded.
Effects can raise or lower indicated dice, within the dice’s range of 1–6. A two-die card modifies two different categories by one each or is not used; it cannot apply both adjustments to the same die. A card showing plus and minus allows a choice of a one-step increase or decrease.
In the Gift phase, a Church card placed facedown into the future Auction pile is not activated yet. It becomes available for its effect when somebody actually wins it at auction.
Final scoring, category ties and overall ties
After every Auction card is purchased or discarded, players total the values in each of the five categories. The highest total in each category wins the corresponding Scriptorium die as victory points.
If players tie for the highest value in a category, the winner is the tied player holding the category card with the earliest alphabetical tie-breaking letter (the letter nearest A).
Add the numbers shown on all category dice you won. Highest sum wins. If the final totals tie, the player with more Gold remaining wins. Further ties use who won the Monk category, then additional category comparisons in the rulebook’s specified order.
Eight rules-based Biblios strategy ideas
- Watch the five dice. A category with a high die is worth more than an equally contested low-valued category.
- Draft Gold as spending power. Winning categories often depends on a key auction purchase later.
- Do not neglect public choices. Every Gift-turn allocation gives opponents useful cards; consider which cards they are likely to take.
- Track category leaders. A single 4-value card may outweigh several lower-value cards in the same color.
- Put meaningful cards into the Auction pile deliberately. You may later be able to buy them, but other players also get a chance.
- Use church effects for leverage. Raising a die in a category you expect to win increases your final reward; lowering a rival’s likely category reduces theirs.
- Bid only what you can pay. Failure to pay can cost multiple random cards, far worse than overpaying one Gold.
- Distinguish card count from card value. For Gold auctions, the number of cards matters; for normal auctions, Gold value matters.
These are original strategic deductions, not claims of hands-on playtesting.

No. Each card is allocated when drawn.
Can a player re-enter bidding after passing?
No, not for that particular auction.
What is the currency for regular card auctions?
Gold values from the Gold cards in your hand.
How do you bid for a Gold card?
Using the number of cards you are willing to discard, rather than Gold values.
When are Church cards activated?
Immediately when acquired, not when first placed in the facedown Auction pile.
What breaks a tie for a category?
The earliest tie-breaking letter among the tied players’ matching cards.
What breaks an overall victory-point tie?
Remaining Gold first, followed by category-based tie-breakers.
Who should play Biblios?
Best for 2–4 players who enjoy card drafting, auctions and competing for majorities. Biblios rewards careful allocation and reading what other players need; it is less suitable for groups wanting a purely cooperative or luck-free puzzle.
