◆Detailed rule explanation

In Millionaire, when you put a card into play, you always turn it face up, but in Million Doubt, you can choose to put it face up.
For example, if there is a K on the field and an A and a 3 in your hand, the following three ways to play are allowed.

1. Roll A face up
2. Roll A face down
3. Roll a 3 face down

●About Doubt
Other players can inspect the cards played face down (hereinafter referred to as the back cards) by declaring a doubt. If the back card is incorrect (in the case of number 3 in the example above), the doubted player will execute the penalty, and the doubted player will receive the penalty. The reverse is true if the back bid is legal.

●About penalties
The penalty enforcer can hand out any number of cards from the cards on the field (hereinafter referred to as tableau piles) to the player who will be penalized. Cards not used for penalties are discarded.

●About how to put out the back card
About how to combine face-up cards (hereinafter referred to as front cards) and back cards
When players play cards, they can play any number of cards as a back pile.
For example, when rolling out 4 diamonds, 4 spades, and 4 clovers, the player can select the number of back cards from 0 to 3. In the case of 3 hearts, 5 spades, 7 diamonds, etc., you can put two or more cards onto the field at the same time by turning them face down.

●How will the next player handle the back card?
If the previous player's card contains a back card, the player may interpret the back card as a favorable card and play it. For example, if there are 5 back-to-back diamonds, it may be interpreted as 3 diamonds, 4 diamonds, 5, or 5 clovers, 5 spades, and 5 diamonds.
However, if the previous set of cards is all face down, it is treated as if there are no back cards.
#The "card set" here refers to the cards that are put into play at once.
#Joker as a wild card is treated exactly the same as a back card.

●About Doubt and Through
Doubt can be declared when a face down card is put into play.
All players can declare a doubt.
When explicitly declaring that you do not want to doubt, distinguish it from "pass" and declare it as "through."

◆Other rules

●Revolution
Conditions for success: One of the following must be met.
1. Put 4 or more cards into play at once and don't get doubted.
2.If 4 or more cards come into play at once and are doubted, but the doubted player fails.
Effect: The strength of the cards is reversed, with 3 being the strongest and 2 being the weakest (if the number of revolutions is an even number, 2 is the strongest and 3 is the weakest).
#However, Joker is always the strongest card unless treated as a wild card.

●8 slices
Establishment condition: A card set containing the number 8 on the faceplate is placed on the field.
Effect: Discard all tableau cards and start from the turn of the person who rolled an 8.

●11 back
Establishment condition: A set of cards including the number 11 on the nameplate is placed on the field.
Effect: The strength of cards is temporarily reversed until the field flows.

●Suit binding
Condition: A card set containing a nameplate of the same suit as the nameplate of the previous card set is placed into play.
Effect: Only cards that include the target suit can be played.
#Joker and the back card are treated as having no suit.

●Burst
Success condition: The number of cards in any player's hand becomes 11 or more.
Effect: Gives points worth the amount of cards in their hand to players who are not up and leaves the game midway.

◆About score calculation
The score calculation is as follows.
Score when winning: Number of cards in enemy's hand
Points conceded when losing: Number of cards in your hand

This app calculates your own rating based on the points scored above and evaluates your ability.

The duration is 1 minute, and each action adds 10 seconds to the duration. The maximum duration is 1 minute.

◆Basic rules

1. Randomly deal 7 cards to 3 players. Includes 2 Jokers.

2. The game starts with the parents. The first parent plays the first card from their hand, and the next player in turn plays and stacks the cards.

3. Cards have strengths, in descending order of strength: 3, 4, 5, 6, 7, 8, 9, 10, J, Q, K, A, 2 (the reverse is true for revolution and 11 back). Joker is not affected by revolution and can be used as a stronger card than 2 in normal times and stronger than 3 in revolution.

4. The next player can only play cards that are stronger than the current card on the field (example: 9 is on the field → they can only play cards with a strength of 10 or higher). Also, you can play a card regardless of whether you have passed in the past.

5. Passing is allowed when there are no cards to play, or when you don't want to play them strategically (e.g., you want to save the strong cards in your hand until the second half of the game). Further, the number of passes is not limited.

6. When all other players have passed and the player who played the cards on the table has their turn again, that player becomes the parent. The cards on the field are swept away (kicked to the side), and the parent can play any card they like from their hand.

7. Parents can play multiple cards with the same number (e.g. 4 spades, 4 diamonds, 10 diamonds, 10 hearts, 10 clovers, etc.). If more than one card is on the table, the player must put out the same number of cards stronger than that number as there are on the field. For example, if there are two 5s, you need to play two pairs of cards with a strength of 6 or higher. When using jokers, you can also play them in combination (e.g. ``1 7 and 1 joker'' instead of ``2 7s'') (However, in that case, the joker is the other number played. Since it is treated as the same card as , it is no longer the strongest card).

8.Repeat the above steps, and the player who has no cards in hand becomes the winner and calculates the score.

That's all for the rule explanation.

◆FAQ

●Why are there no special rules such as special 3 return, emperor, 5 jump, 7 pass etc?

We did not adopt this method because it does not improve the strategic nature of the game considering the learning cost for the player.
8-cut, Kakumei, 11-back, and Shibari are well-known, have a low learning cost, and have a big impact on the game, so we chose them.

●Why is the back card and Joker as a wild card treated the same?

There are two reasons.
1.The learning cost for players is lower if back cards and wild cards are treated the same.
2. Eliminating user-selected phases increases the tempo of the game.

●Are there any other similar products, and if so, what are the differences?

There are other ideas for mixing Doubt and Millionaire.
The differences between them are that some parts can be turned face down, the tempo of the game is pursued, and even the point calculation is set.

●Why not deal all the cards?
This is to shorten the time per game and improve the tempo.

●Why is there a burst rule?
This is to shorten the time per game and improve the tempo.

●Isn't this game a game called Fraudulent Millionaire?
yes. In the past, it was called by that name, but due to adult circumstances, it was renamed Million Doubt.
