The word "Keno" has French or Latin roots (Fr. quine five winning numbers, L. quini five each), but by all accounts the game originated in China over 2000 years ago. Legend has it that the invention of the game saved an ancient city in time of war, and its widespread popularity helped raise funds to build the Great Wall. According to one source, results of Keno games in great cities were sent to outlying villages and hamlets by carrier pigeon. Eventually, Chinese immigrants introduced Keno to the West when they sailed across the Pacific to help build the American trans-continental railroad in the 19th century.

Keno is similar to lotto games, in that players have a card or ticket with numbers that are selected in hopes of matching the numbered balls that are drawn during play. Early Keno games looked for a match of five numbers to win. Some Keno dealers used a large jar with a long, thin neck to tumble the balls. The neck was just wide enough to permit only one ball at time to flow, thus eliminating any argument about which number was drawn. For obvious reasons, this jar was called the "Keno goose".

Game Play:

First, players must purchase a Castle Keno ticket. To buy a ticket, place a $1 chip in the circle marked “Place Bets” on the Betting Board. None of the betting options can become active until a ticket is purchased.

Next, players try to predict which numbers will be drawn by marking from 1 to 15 of the numbered blocks (“Spots”) on the wall. To mark a block simply mouse over the block and click it. The block will change color to indicate it has been marked. As you mark each block, the Spots counter at the bottom of the screen will increment. (Note that it is possible to mark more than 15 Spots, but the numbers can’t be drawn until the number of Spots is reduced to 15 or less). To remove a mark, just click on the block and it will change back to the original color (and decrement the Spots counter).

There are five betting options in Castle Keno. Each option requires a certain number of Spots to be marked before it becomes active. As you mark Spots, the buttons for the options will light up when you have satisfied their minimum and maximum Spots requirements (see Betting Options below).

When you are satisfied with the arrangement of your Spots, click the desired betting option on the Betting Board to start the game. Twenty rocks will be hurled toward the Castle, striking different numbered blocks at random. As each rock smashes a block in the wall, a flag will unfurl to display the corresponding number. When a number you marked on the wall is struck by one of the rocks, that’s called a “hit”.

After the final rock has found its target, the player will be paid according to how many of the rocks hit marked blocks based on the payout table for the chosen betting option.

BETTING OPTIONS:

Our Keno game is played with a traditional 80-numbered ticket and a draw of 20 numbers whose function is similar to a standard lottery. The ticket is sectioned into a two halves, with numbers 1-40 on the top and 41-80 on the bottom. We've added a fun twist to the game by presenting the ticket as a Castle wall, with the 80 numbers painted on granite blocks that make up the wall. Instead of drawing balls to announce winning combinations, we use a rock thrown from a catapult to hit the block corresponding to each number drawn. Will the rock smash the blocks you selected? It’s fun to watch the wall crumble as you find out!

The five different ways to bet on a Castle Keno ticket are:

1. BET
2. BET AGAINST
3. HIT ALL
4. HIGH ROLLER
5. TOP OR BOTTOM

BET

The BET option is enabled once you mark at least one spot on the Keno ticket. (When you click BET, the game starts – so don’t click it until you are finished marking your numbers.) You can mark up to 15 of the 80 possible numbers, but no more than 15. You are paid if one or more of the numbers you marked is smashed by a rock from the catapult. When a number you marked on the wall is struck by one of the rocks, that’s called a “hit”.

Let’s say you mark 7 numbers. If any 4 of those 7 numbers get hit, you are paid $5. If any 5 of those 7 numbers are hit, your payoff is $20. If 6 of the 7 numbers get hit, it jumps to $250, and if you hit all 7 numbers, you win $2000!

The following is the Bet option payout table for a $1.00 ticket. The way to read the table is as follows:

BET AGAINST

BET AGAINST is enabled once you have marked at least 8 Spots on the ticket. With this option you are betting that none of the numbers you mark will be hit by any of the rocks thrown. You are paid only if none of the marked numbers get hit. The following is the Bet Against Payout table for a $1.00 Castle Keno ticket.

Spots Marked	Payout ($)
15	80
14	56
13	39
12	27
11	20

HIT ALL

The HIT ALL option can be played with 2 to 7 Spots marked on the ticket. You are betting that all the numbers you mark will be hit. You will be paid only if all the numbers you marked are among the 20 hits on the wall. The following is the Hit All Payout table for a $1.00 Castle Keno ticket.

Spots Marked	Payout ($)
7	28,000

HIGH ROLLER

The HIGH ROLLER option is enabled once you mark at least one Spot on the Castle Keno ticket. HIGH ROLLER is played almost like the normal BET option, but the Payout is on a different schedule where you have to Hit more Spots in order to get paid, but when you do Hit them the Payout is greater. The following is the High Roller Payout table for a $1.00 Castle Keno ticket.

Mark 1 Hit Payout ($) 1 2.80	Mark 2 Hit Payout ($) 2 11.20	Mark 3 Hit Payout ($) 3 40 2 0.80

TOP OR BOTTOM

TOP OR BOTTOM is the only option that is enabled before you mark the ticket. You only need to place your bet to be able to use this option. You are betting that the top or bottom half of the ticket will have significantly fewer hits than the opposite half. You don’t mark any spots, and you don’t need to choose the Top or the Bottom. You’re just betting that there will be a large difference between the hits each half gets.

The greater the difference, the bigger the payout. The following is the Top or Bottom Payout table for a $1.00 Castle Keno ticket.

Hits on Top or Bottom	Hits on Other Half	Difference in Hits between Halves	Payout ($)
7	13	6	1
6	14	8	4
5	15	10	10
4	16	12	40
3	17	14	200
2	18	16	600
1	19	18	4,000
0	20	20	10,000
