I've been playing with this one (live bets, not paper tracking), $1 or $2 a day, it's been kicking back 2 out of 5 a few times - $1 payoff, break even, and an occassional 3 out of 5 for $10, and has been coming close to 5 for 5. 

Just for fun (this is Illinois Little Lotto, a 5/ 39 game) Take the previous day for your state, all the drawings.

Example Illinois Dec 20 '07

Pick Three Midday:   967

Pick Three Evening: 752

Pick Four Midday: 4107

Pick Four Evening: 9257

Little Lotto: 5 23 26 35 38

From the above:    967 = 9 + 6 + 7 = 22

752 = 7 + 5 + 2 = 14

4107 = 4 + 1 +0 +7 = 12

9257 = 9 + 2 + 5 + 7 = 23   

Little Lotto- here's what I do, above you have 12 14 22 23 - usually the lowest number drawn is in the 1-9 or 1-10 range, so I take the highest two numbers from yesterday's Little Lotto and subtract them, in this case

38 - 35 = 3

So the play would be   3 12 14 22 23 I played that tonight, the results were 3 22 25 28 34 So it caught the 3 and 22 for $1 (break even).

It's a real easy "paper and pencil" workout for dollar players. You just have to "tweak" how you get the low number and what numbers you use to get it. Good luck.
