Two cards are turned up and players bid to win the cards until all cards have been distributed. The more of the same colour you have, the more points you score.
Bidding circulates from the active player with raises or dropping out until only one player remains who wins the bid and pays the amount stated.
You can bid more than you can afford, overbid. However, this labels you as an offending player. As such, if you win the bid, you get nothing, and instead have to discard a previously gained card. In addition, the bidding is re-opened with the offending player excluded for that bidding round.
If all other players pass on the first cycle, the active player wins the card set for free (free is not 0)
When making a bid, your singles digit cannot match a number card you already won previously (e.g. if you win card "4" you cannot bid 4 or 14 or 24 & so on)
When bidding is finished, the payment is not given to a bank, but instead to another player(s)
If another player has a card number matching the payment number, they win the payment (e.g. you win card 3, pay 4, player x with card 4 would get the 4 money)
As with bidding, we are looking at the single digit of the payment number (e.g. you bid 14, player x with card 4 would get 14 money)
Whoever wins the bid becomes the new active player
The winner of the bid can never take payment, no matter how they may qualify
If two or more players have the same number card, the payment is split (e.g. you bid 14, player x & y have one card 4, they each receive 7 money)
If two or more players have the same number card, but in different quantities, the player with the majority wins (e.g. you bid 14, player x has two card 4s & player y has one card 4, player x would get 14 money)
If no one owns the card, all except the winning bidder receives an equal share
If the winnings need to be shared, any excess is set aside for the next bid (e.g. a bid of 7 wins card 4, x and y have one card 4, so each get 6 money. A bid of 3 wins card 6, added to the leftover this makes 4, so x & y with one card 6 get 2 money each)
If you are low on money, you may be offered to perform an auction of your own. This allows you to sell off one of your own cards, during this type of auction the active player receives all the money.
Once all cards have been won, scoring occurs as follows:
Scoring is based on colour of cards, not number
1 card of colour x = 1 point
2 card of colour x = 3 points
3 card of colour x = 6 points
4 card of colour x = 10 points
5 card of colour x = 15 points
Bonus: Most coins at endgame = 2 points (2 points each if tied)
Endgame Tiebreaker: highest sum of all numbers held
