1.1 Upgrade: Use check boxes to pick your keno numbers instead of typing them in. I cleaned up the formatting on the tabled graphics (so it looks better in Netscape browsers) and added the ability to change more of the layout features. Compare demos below and you will see the improvement.

Keno is one of the oldest casino games around, originally created during the Han dynasty in China. It has changed slightly over the last 2000 plus years, but still is actually one of the easiest casino games to play. You pick between 1 and 15 different numbers between 1 and 80 (known as "spots") and try to match all your spots against the 20 randomly drawn numbers.

                   catch 15 100,000

Notes: As you can see from the chart above, the more spots chosen, the harder it gets to "catch" (match) them all. If I played the same 10 numbers it would, mathematically speaking, take me almost 9 million games to match all 10 spots! (Theoretically, with tdkeno.cgi it would be possible to test these mathematics, by setting your score to 9 million and then playing 9 million games with the same 10 numbers, but yikes, this would really tie up a servers resources and probably take a few hours or so to fully execute)

Strategy: A good strategy might be to try to go for no more than 5 or 6 spots, but preferably 2, 3 or 4 spots tickets, since the lower numbers offer better probabilities. No matter how you look at it, Keno has the worst odds of any game in the casino, but it's fun trying to beat the odds.

Some Suggested Script Uses:
1. Use TD Keno as an enticement to garner email addresses for marketing purposes. Just
     make sure you notify the players logging in that you are doing this, and provide them
     some way to unsubscribe from your mailing list if they want to.
2. You could easily frame the script and show banner advertisements while players are trying
     to beat the high score.
3. Make a contest where a certain high score would yield some type of prize or discount off
     items you are selling at your website.
4. Place the script 'as is' in your members-only area to improve retention and enhance the sense
     of community at your website.
5. Have TDavid customize the script in some other way for you ... use the formail script for inquiries.
