# Penny Keno

## Introduction

Penny Keno is a format of playing multi-card keno I saw at the Swinomish casino in Anacortes, Washington, in July, 2023. It is basically regular keno, except the player buys 110 to 220 cards $0.01 games at once. The game conveniently gives the player 12 patterns to choose from in the way his cards are arranged.

## Rules

- All individual bets are $0.01.
- The player will pick one of the following patterns: K,E,N,O,C,A,S,H,F,D,I,coverall.
- Depending on the pattern, much the card will be daubed in about 20 different groups, identified by various letters (not to be confused with the design of the card, which is usually also a letter).
- These groups will be combined together or sometimes stand alone as a single card for form a multitude of cards. The types and number of each type of card are shown below.
- As usual, the game will draw 20 numbers without replacement from a range of 1 to 80. If a number chosen on one of the player's cards match the random draw of the game, that will count at a "catch."
- The player will be paid according to the number of picks and catches on each card and the pay table below.

The following is the pay table for Penny Keno. Note there is no column for picking 7 or 9 because the game never arranges groups of picks of those sizes.
