## Abstract

A method for modifying a computer-based card game via changing probability of picking one or more cards from a deck or decks of cards. The method includes the following steps: Initially all cards have equal probability to be drawn from a shuffled deck The probability to be drawn from the deck for one or more cards in the deck or decks is changed either by program or by the players The cards are drawn from the deck during the game based on the assigned probability

## Claims

### Claim 1

A method for modifying a computer-based card game via changing probability of picking one or more cards from a deck of cards comprising the steps:
starting with the assumption that all cards have equal probability to be drawn
changing card probability to be drawn from said deck for one or more cards in the deck
providing cards from the deck during the game based on the assigned probability

### Claim 2 (depends on 1)

The method from claim 1 where said probabilities are assigned automatically by a program and all players are informed about values of said probabilities

### Claim 3 (depends on 1)

The method from claim 1 where each player assigns a probability to one or more cards and does not share the knowledge of this probability with the rest of the players

### Claim 4 (depends on 1)

The method from claim 1 where each player assigns a probability to one or more cards where assigned number of said cards and their probabilities are further constraint by random device outcome and the player does not share knowledge of the assigned probabilities with the rest of the players

### Claim 5 (depends on 1)

The method from claim 1 where a player is allowed to change a probability of one or more cards to be drawn during the game

### Claim 6 (depends on 1)

The method from claim 1 where a probability to be drawn from a deck is provided by a program for some cards and a player is allowed to change a probability of one or more other cards

### Claim 7 (depends on 1)

The method from claim 1 where multiple decks are allowed

### Claim 8 (depends on 1)

The method from claim 1 where players who are allowed to change probability of one or more cards are randomly selected by a program
