This week’s ticket is really good if you like getting lots of free plays. Mark the ticket using 12 spots, and group them in six deuces (groups of two.) Note in the sample ticket illustrated below, the last group of two is not circled. This is in accordance with the traditional conventions of Keno, where the last group is understood to be a group, even if it is not specifically circled.

This ticket is specifically designed to get lots of free plays, hence the deuces are played for $1.00 per way, twice the amount wagered on the six spots. When a deuce is hit, it pays $12.00, thus paying for the entire ticket. This strategy of playing is called “bottom loading.” A “bottom loaded” ticket has more bet per way on the small ways than on the top ways, and typically produces more pushes and small winners. The ticket is in the style of a deuce way ticket, because the sixes are made up of deuces, and thus this is referred to as a deuce way six spot.

There are only 28 possible different catches on the ticket, with the most common being 1-1-0-0-0-0, about once every 4.62 games. The most common paying catch (paying more than the cost of the ticket) is 2-1-1-0-0-0, about once every 10 games. The most common solid six is 2-2-2-1-0-0, which occurs about once every 939.18 games.

Here are the complete frequencies and odds for the sixes and deuces on this ticket:

Thus, you can expect to hit a deuce almost every third game, getting your money back, and you have a decent chance at a 5-6 or a solid six hit.
