1. Context
Mot Coin is the most reliable cryptocurrency in the universe. Every time a HardFork (split) occurs, it divides in two. Which cards should you buy? Buy as many as you can until you sell and make your fortune. Don't worry: with prices soaring like this, you are sure to make a killing! A market crash? Don't worry too much!

3. Setup
-
Shuffle the 24 Mot Coin and HardFork cards face down to form the draw pile.
-
Each player receives a number of dice based on the number of players:
- 9 dice for 3 players
- 8 dice for 4 players
- 7 dice for 5 players
These dice are called "available dice".
-
Each player receives 1 Stable Coin. Set aside the remaining Stable Coins.
-
Each player places 3 of their available dice showing the faces "4", "3" and "2" on their Stable Coin. These dice are called "price fluctuation dice".

4. How to Play
The game is played in two rounds. Once the draw pile is exhausted, the discarded cards are shuffled to form a new draw pile, and the second round begins. The game ends immediately when the 4th HardFork card is put up for auction.
The game progresses by repeating these steps: "4.1 Determine the card to auction", "4.2 Bidding" and "4.3 Price fluctuation".
4.1 Determine the card to auction
First round: Reveal the first 2 cards of the draw pile face up. Put up for auction the card with the lowest number. Place the other card (higher number) face down in the discard pile. Keep the discard pile separate from the draw pile. You may look at the contents of the discard pile at any time.
Second round: Reveal the first card of the draw pile face up and put it up for auction.
Cards No. 4 and No. 5 trigger a double auction (see the special section, p. 3).
Example (as printed): If cards No. 2 (price 15) and No. 15 (price 26) are revealed, No. 2 is put up for auction and No. 15 goes to the discard pile.
Note: the printed example prices do not match the card list in section 9. Card No. 2 is printed with price 11, card No. 15 with price 23, and price 26 is card No. 19. The example is transcribed as printed; the card list is authoritative for card values.
4.2 Bidding
Starting with the first player and continuing clockwise, players bid or pass.
To bid, a player presents any number of available dice (dice not used on other cards) showing any faces of their choice. Price fluctuation dice (the dice on the cards) cannot be used for bidding.
Each following bid must be "stronger" than the previous one. To compare the strength of a bid, first compare the number of dice showing a "6". If they are equal, compare the "5", then the "4", and so on down to "1". You can never bid with a strength equal to or lower than the previous bid.
Example 1: Mori plays four dice showing "5". Rikachi plays a single die showing "6". Rikachi wins the bid because a "6" is stronger than four "5". Example 2: Rei plays a "6" and three "1". She beats Rikachi because she has as many "6" but more "1". Example 3: Mimura plays a "6" and a "5". She beats Rei because she has more "5".
If a player passes, they can no longer take part in the bidding for this card. The bidding continues until only one player remains.
When a player makes a new offer, they take back their previous dice and offer a new, stronger combination.
The last active player wins the card and becomes the first player for the next auction. They place the dice used on the won card, face up: they become the new "price fluctuation dice".
If all players pass without bidding, the card is removed from the game and not discarded. The first player stays the same.
The winner of the auction places the card won in front of them and places all the dice they used to bid on the card, keeping the faces of the dice as they are. These dice are called "price fluctuation dice". If the winner already has other cards won earlier, make sure the cards do not overlap and the dice do not get mixed up.
The dice used by the winner to bid are placed on the won card and remain price fluctuation dice until they return to your pool of available dice.
4.3 Price fluctuation
The player who won the card clearly announces to the others the card's "price fluctuation value".
All other players adjust the faces of all their fluctuation dice (on all their cards) by this value. If all players passed and the card is removed from the game, the fluctuation value is automatically -1 for everyone.
- If the value is positive, all fluctuation dice increase by that amount (bad!). If a die goes above "6", it stays at "6".
- If the value is negative, all dice decrease by that amount. If a die drops below "1", it returns to your available dice (lucky!).
- If the card says "Remove one die", you must take back the die (into your available dice) with the lowest value among your fluctuation dice.
Example (as printed): Mori, Rikachi and Rei did not win the card, whose fluctuation value is -2. Rikachi has four dice on his cards showing "6", "6", "2" and "1". After applying -2, he keeps two dice showing "4" and the other two return to his pool.
End of the 1st round and start of the 2nd
If cards remain in the draw pile after completing step "4.3", return to step "4.1" and start the next auction. If the draw pile is empty, the first round is over. Shuffle the discard pile to form a new draw pile and start the second round.
During the second round, if the 4th HardFork card is revealed during "4.1", it is not put up for auction: the game ends immediately.
Note: There are 4 HardFork cards, but it is not known which will be the 4th. The 4th (No. 24) can never appear in the first round. The game therefore cannot end before the second round.
5. Scoring
When the game ends, scores are calculated to determine the winner. Follow these steps in order: "5.1 Price rise", "5.2 HardFork split" and "5.3 Market crash".
5.1 Price rise
Prices go up... and fast!
Each player stacks their won Mot Coin cards starting with the lowest price. If the gap between two cards is 3 or less (for 3 players) or 4 or less (for 4 or 5 players), the card with the lower price is stacked under the card with the higher price (this is a good thing!). If several cards are already stacked, they are all moved under the next one. All price fluctuation dice are also moved to the top card.
Finally, each Mot Coin in the stack takes the price of the top card. For example, if 4 Mot Coin are stacked under a card worth 29, they are all worth 29. Total = 145.
Example (as printed): In a 3-player game, Mimura has won the following 5 Mot Coin, with prices "15", "17", "20", "25" and "26". The three Mot Coin priced 15, 17 and 20 have price differences of less than 3, so they are all stacked under the Mot Coin priced 20, giving 3 Mot Coin priced 20. All price fluctuation dice on them are also moved to the Mot Coin priced 20. The Mot Coin priced 25 and 26 are stacked under the Mot Coin priced 26, giving 2 Mot Coin priced 26.
5.2 HardFork split
(The source heading reads "Sission des HardForks"; the rules describe a split, so the heading is rendered as "HardFork split".)
The blockchain on which Mot Coin rests undergoes another protocol change. Great: your Mot Coin are now doubled in both specifications... But what about the price?
The value of a HardFork is equal to twice that of the cheapest Mot Coin you own.
The value of a Stable Coin is equal to that of the cheapest Mot Coin you own.
This value is determined after step "5.1 Price rise". For example, if a Mot Coin was worth 17 but was stacked under a card worth 30, its new value is 30. All HardFork and Stable Coin then use this new price as their basis.
Price fluctuation dice present on HardFork and Stable Coin are never moved. If you own only HardFork and Stable Coin, their value is 0.
Each player then adds up the values of all their Mot Coin, HardFork and Stable Coin to calculate their "profit".
Example (as printed): The price of the HardFork here is 40 (2 x 20). The price of the Stable Coin is 20.
5.3 Market crash
Oh no! The Mot Coin market, so high up, has just collapsed!
Each player calculates the losses suffered because of the crash, based on the price fluctuation dice present on their Mot Coin, HardFork and Stable Coin.
Each die causes a loss equal to the card's crash value × the die's face. For example, a card with a crash value of -7 holding one die showing "4" and one die showing "6" causes a loss of (4+6) × 7 = -70.
The crash value is shown at the bottom right of the card in red. Any die remaining on a card at the end of the game will cost you dearly!
Example (as printed): card No. 12, whose crash value is -3, carries dice whose total is 9, causing a loss of -27. In addition, card No. 15, whose crash value is -6, carries one die showing "1", causing a loss of -6. In total, the market crash causes a loss of -33.
Note: the printed example gives card No. 15 a crash value of -6, but the card list in section 9 shows card No. 15 with crash value x-4 (the x-6 value belongs to card No. 19). The example is transcribed as printed.
6. Determining the winner
Remaining available dice count neither as gains nor as losses.
The player with the highest total after subtracting losses from profits wins the game. Even if this total is negative, the highest total wins.
In case of a tie, the victory is shared.
7. Special auction: cards No. 4, No. 5 and Stable Coin
If card No. 4 or No. 5 is put up for auction, it is a double auction.
Take a Stable Coin from those set aside and place it next to the card put up for auction.
In a double auction, at the end of the auction:
- The player who made the strongest bid wins the Mot Coin card as usual.
- The player who passed last (2nd best bid) must receive the Stable Coin. The dice used for this last bid are placed on the Stable Coin as fluctuation dice. To obtain a Stable Coin, a player must have bid at least once. A player who only passed is not entitled to one. If there is no other bidder (or no bidder at all), the Stable Coin is removed from the game (it is not placed in the discard pile).
The player receiving the Stable Coin does not carry out step "4.3 Price fluctuation" for the Mot Coin winner. In other words, the winner and the player who acquires the Stable Coin do not benefit from the "Remove one die" effect of cards No. 4 and No. 5.
8. FAQ
Q: During the following turns of an auction, can I change the number and faces of the dice I bid previously? A: Yes. As long as you make a stronger bid, you may use any number of available dice, including those you have already played, showing faces of your choice.
9. Card list
Each Mot Coin and HardFork card is unique (one card per number). There are 7 Stable Coins (at most 2 may be put up for auction).
Cards with low numbers (more likely in the first round) generally have poor fluctuation values, while those with high numbers (second round) have better values.
Therefore, during the first round, since "price fluctuation dice" are less likely to come back, except in the case of HardForks, be careful not to be carried away by the auctions. During the second round, although price fluctuation values are large and many dice may be bid, if the game ends suddenly, there is a strong chance of heavy losses.
The card list below is transcribed from the card-list figure in the source document (the source shows the cards as images, not as a table). Values are read from a low-resolution image; the fluctuation value is shown by the chevron icon and the number beneath it, and the crash value is the red multiplier at bottom right. "—" means the card shows no fluctuation or crash value.
| Card | Type | Price | Fluctuation value | Crash value |
|---|---|---|---|---|
| No. 1 | HardFork | MIN × 2 | -3 | × -12 |
| No. 2 | Mot Coin | 11 | +1 | — |
| No. 3 | Mot Coin | 12 | +1 | — |
| No. 4 | Mot Coin (Double Auction, 1st) | 13 | -1 | × -1 |
| No. 5 | Mot Coin (Double Auction, 1st) | 14 | -1 | × -1 |
Note on the figure: the "MIN × 2" and "MIN × 1" prices on the HardFork and Stable Coin cards mean the value is set by the rules in section 5.2 (twice, or once, the cheapest Mot Coin owned).
