The 123 rundown is the simplest Pick 3 rundown there is, and one of the most searched. This guide shows exactly how it works, step by step, with a full worked example you can check by hand, and what the L Numeris app shows you on top of it.
What a Rundown Is
A rundown takes one starting Pick 3 number and adds the same three digits to it, row after row. The 123 rundown adds 1 to the first digit, 2 to the second and 3 to the third. Whenever a sum goes past 9, you keep only the last digit (8 + 3 = 11, keep 1). That rule is called mod-10, and it keeps every digit between 0 and 9.
Step 1: Start With Your Draw
Use the most recent Pick 3 draw for your state. That is your top row. In our example the draw is 5-1-8.
Step 2: Add 1, 2 and 3
- First digit: 5 + 1 = 6
- Second digit: 1 + 2 = 3
- Third digit: 8 + 3 = 11, keep 1
The next row is 6-3-1.
Step 3: Keep Going
Do the same to each new row:
- 6 + 1 = 7; 3 + 2 = 5; 1 + 3 = 4. Next row: 7-5-4.
- 7 + 1 = 8; 5 + 2 = 7; 4 + 3 = 7. Next row: 8-7-7.
Step 4: The Full Rundown From 5-1-8
- Row 1 (your draw): 5-1-8
- Row 2: 6-3-1
- Row 3: 7-5-4
- Row 4: 8-7-7
- Row 5: 9-9-0
- Row 6: 0-1-3
- Row 7: 1-3-6
- Row 8: 2-5-9
- Row 9: 3-7-2
- Row 10: 4-9-5
- Row 11: 5-1-8 (your draw again)
After ten steps every digit comes back to where it started, so row 11 is your draw again. That gives you 10 different numbers.
Three Things Worth Knowing
Each column counts at its own speed. The first digit goes up by one every row: 5, 6, 7, 8, 9, 0, 1, 2, 3, 4. The second goes up by two, and the third by three. That is why the 123 rundown is the easiest one to check by hand.
123 and 369 give the same ten numbers. One step of the 369 rundown is three steps of 123, because 3 × 1 = 3, 3 × 2 = 6 and 3 × 3 = 9. Start both at 5-1-8 and you get the same ten numbers in a different order. So running both is not twice the coverage.
Zone 2 half-mirrors Zone 1. Five rows down, each column has moved five steps. Where the rundown digit is odd (1 and 3), the digit becomes its mirror (+5). Where it is even (2), it comes back the same. In the example, row 2 is 6-3-1 and row 7 is 1-3-6: the first and third digits mirrored, the middle one repeated.
Reading the Grid in L Numeris
The 123 Rundown generator does the arithmetic for one credit and lays the 11 rows out as a grid. On the screen you will also see:
- Two zones: brackets around rows 2 to 5 and rows 7 to 10. They change no numbers; they mark where to look.
- Hit Sum (green): your draw's digits added, last digit, and the next digit up. For 5-1-8 that is 4 and 5.
- Day Sum (yellow): the month plus the day of your draw, last digit, and its mirror.
- Hot Numbers: the mirrors of your state's last twelve draws. Tap one and its paths light up in your grid.
- Quick Stats: the odds for any number you pick, and what a field of tickets costs, box or straight.
Common Mistakes
- Forgetting the mod-10 rule. 8 + 3 is 1 here, not 11.
- Starting from the wrong draw. Use your own state's latest draw for the game you play.
- Playing every row without a plan. Ten numbers is a field to choose from; decide your budget first.
Honest Limits
- A rundown builds a field of candidates, not a prediction. A Pick 3 straight stays 1 in 1,000 for every number.
- Seeing a number in more than one rundown, or in a zone, does not make it more likely to be drawn.
- Set a budget and keep a record of your plays. That is where real learning happens.
