Keno game with extra chances
View Patent ↗A method of playing Keno in which the quantity of numbers drawn is increased by including the integer above and/or below each number drawn, for at least some of the numbers drawn. This effectively increases the quantity of numbers drawn without requiring any additional steps by the players or modification of ball drawing equipment. For example, after drawing 20 numbers, the respective integer above each of the first 5 drawn numbers can be included in the draw. Optionally these extra numbers can be treated differently from those drawn, for example by applying to an additional bonus wager.
1. In a game of chance based on randomly drawn numbers, a method of increasing the probability of winning, comprising the steps of:
a) providing a range of available integers for play;
b) selecting by choice a first subset of integers from the range of available integers;
c) randomly selecting a second subset of integers from the range of available integers;
d) deriving integers according to at least one method selected from the list of steps consisting of,
d.1) selecting the next greater integer above each of at least some of the randomly selected integers and
d.2) selecting the next lesser integer below each of at least some of the randomly selected integers; and
e) calculating winnings based on matches between the first and second subsets and on matches between the first subset and the derived integers.
2. The method of claim 1 wherein the range of integers is treated as a circular list in the derivation steps d.1 and d.2, so that each derived integer is within the range of available integers.
3. The method of claim 2 wherein if a given derived integer matches one of the drawn integers, then the given derived integer is replaced with another available integer that is numerically close to the given derived integer.
4. A method of playing Keno with extra chances of winning, comprising the steps of:
a) providing a range of available integers for play;
b) a player choosing a first subset of integers from the available integers;
c) an operator randomly drawing a second subset of integers from the available integers;
d) the operator deriving a third subset of integers comprising the nearest available integer not drawn above each integer drawn for at least some of the integers drawn; and
e) the operator calculating winnings based on matches between the first and second subsets and on matches between the first and third subsets.
5. The method of claim 4 wherein the range of available integers is treated as a circular list in derivation step d) so that each derived integer is within the range of available integers.
6. The method of claim 5 , wherein if a given derived integer matches one of the drawn integers, then the given derived integer is ignored.
7. The method of claim 5 wherein if a given derived integer matches one of the drawn integers, then the given derived integer is replaced with the next higher available integer not drawn in the range of integers.
8. A method of playing Keno with extra chances of winning, comprising the steps of:
a) providing a range of available integers for play;
b) a player choosing a first subset of integers from the available integers;
c) an operator randomly drawing a second subset of integers from the range of available integers;
d) the operator deriving a third subset of integers comprising the nearest available integer not drawn below each integer drawn for at least some of the integers drawn; and
e) the operator calculating winnings based on matches between the first and second subsets and on matches between the first and third subsets.
9. The method of claim 8 wherein the range of available integers is treated as a circular list in derivation step d) so that each derived integer is within the range of available integers.
10. The method of claim 9 wherein if a given derived integer matches one of the drawn integers, then the given derived integer is ignored.
11. The method of claim 9 wherein if a given derived integer matches one of the drawn integers, then the given derived integer is replaced with the next lower available integer not drawn in the range of integers.
