  In Pick 3 (a game with 3 digits, 0-9 in each position), many people use the concept of digit skips/delays to create filters and try to reduce the number of combinations played.

  The most common system for lag groups is to divide digits into 3 categories depending on how many draws they are "delayed" (haven't appeared):

  Short (small/recent delay) → digits that appeared recently
  Medium (moderate delay) → digits "in between"
  Long (large delay/hot-cold) → digits that haven't appeared for a long time

  Suggested practical classification (widely used in the community)

  Group | Approximate Delay (number of draws without appearing) | Typical examples of expected behavior | Short | 0 to 5 draws | "Hot" or recently appeared digits, tend to repeat frequently | Medium | 6 to 14 draws | Digits in "equilibrium phase", appear with average frequency | Long | 15+ draws (or 20+, depending on the lottery) | "Cold" digits, when they appear they tend to be strong

  Basic filtering system using these 3 Groups
  Objective: To filter combinations that do not respect historical patterns observed in your state/country (e.g., Brazil – Timemania, Federal, or interstate lotteries like New York, Texas Pick 3, etc.).
  Most popular filters with delay groups (choose 2–4 to combine):

  Quantity filter per group (strongest and most used)
  Require at least 1 digit from each group → 1-1-1 (very balanced)
  Or allow only: 2 short + 1 medium or 1 short + 2 medium
  Or completely avoid: 3 long (very rare) or 3 short in a row (sometimes happens, but less often)
  Examples of good rules:
  Minimum 1 short
  Minimum 1 medium
  Maximum 2 long
  Prohibit 0 short (very dangerous)

  Repetition + delay filter
  If 1 repeated digit came out in the last draw → allow only short and medium digits in the next one (long digits almost never repeat right away)
  If no digit was repeated → 1–2 long digits can come out

  Long delay position filter
  Place a maximum of 1 long digit in the same position as the long digit came out in the previous draw
  Or: The most delayed digit (the "king of delays") can only go in the middle position (2nd column).

  Sum + Delay Filter
  The sum of combinations with 3 long digits is almost always very high or very low → eliminate extreme sums (e.g., <6 or >24 when there are many long digits).

  "Don't let the main long digit slip through" Filter
  Identify the digit with the highest current delay (e.g., 22 draws without appearing).
  Require that it be present in the combination (or at least in 70–80% of the plays).

  Practical application example (assuming today's draw):
  Suppose you calculated the current delays as follows:

  Short (0–5): 2, 5, 8
  Medium (6–14): 0, 1, 4, 7
  Long (15+): 3, 6, 9

  Suggested filters to generate few combinations:

  Have exactly 1 or 2 short digits
  Have At least 1 medium length. Have 0 or 1 long length. Prohibit 3 long lengths. Prohibit 0 short lengths.

  Valid combinations would be things like:

  2-0-5 → 2 short lengths, 0 medium lengths, 5 short lengths
  8-1-3 → 8 short lengths, 1 medium length, 3 long lengths
  5-4-9 → 5 short lengths, 4 medium lengths, 9 long lengths
  etc.

  Avoid: 3-6-9 (only long lengths) or 0-1-4 (only medium lengths, no short lengths)
  How to put this into practice?

  Take the last 30–50 results from your Pick 3 lottery.
  Calculate the delay of each digit (0–9) at the current moment.
  Sort them as Short / Medium / Long.
  Use Excel, Google Sheets, or a lottery app to generate all 1000 combinations (000–999).
  Apply the filters above (logical conditions).
  Usually 80–300 combinations remain → play the box or go directly to the strongest ones.

  Let's create a positional strategy for Pick 3 (0-9 lottery game in 3 digits) based exactly on what you asked for: cross the 3 main groups (delays, even/odd and low/high), with the pairs (position pairs: 1-2, 1-3 and 2-3) focusing on the smallest and largest digit in these pairs, and also incorporating hot/cold/medium.

  Basic definitions used in the strategy (standard in Pick 3)

  Low = 0-4
  High = 5-9
  Even = 0, 2, 4, 6, 8
  Odd = 1, 3, 5, 7, 9
  Delayed (delayed): digits that haven't appeared in many draws (e.g., delay ≥ 8-12 draws = strong delay)
  Hot: appeared in the last 1-3 draws (or more frequently in the last 10-20)
  Cold: hasn't appeared in 7+ draws
  Medium (warm/neutral): appeared in the last 4-6 draws or average frequency

  Suggested strategy: "Positional Triple Crossover with Lower/Higher Pairs"
  Objective: Generate more filtered combinations (generally 8 to 30 games per day) using the crossover of the 3 groups + analysis of the pairs.

  Step 1 – Collect current data (do this every day)

  Last 30-50 results of your Pick 3 lottery (morning and afternoon, if separate).

  Calculate for each digit (0-9):
  Current delay (how many draws without appearing)
  Recent frequency (last 10-20 draws)
  Classify each digit as: Hot / Medium / Cold

  Identify the 3-4 most delayed, 3-4 hottest, and 3-4 medium/moderately cold.

  Step 2 – Define the "pools" by group (for each position 1st, 2nd, and 3rd separately)
  For each position, create 3 small lists (4-6 digits each):

  Strong Delay Pool → the most delayed digits (prioritize those with ≥10 draws without appearing)
  Hot Pool → digits that have appeared in the last 1-4 draws (or more frequently)
  Medium/Moderate Cold Pool → the rest (neither too hot nor too delayed)

  Step 3 – Main Crossover Rules (the heart of the strategy)
  For each generated combination, apply all these filters together:

  Even/Odd Pattern (one of the strongest in Pick 3)
  Examples of common patterns that tend to repeat:
  PPP or III (all even or all odd) → 5-10% of the time
  PPI, PIP, IPP (two even, one odd)
  IIP, IPI, PII (two odd, one even)
  Avoid long periods without a pattern appearing (e.g., if you have 12 draws without PPP, prioritize it).

  Low/High Pattern
  Strong patterns:
  BBA, BAB, ABB
  AAB, ABA, BAA
  BBB or AAA (less common, but pays when it comes)
  Combine with even/odd: e.g., "two low + one high and two even".

  Smaller x Larger Pairs in Positions (Central Part of Your Order)
  For each pair of positions, observe the smallest and largest digit: Pair Suggested Rule (Strong Filter) Why? Pos 1-2 Smaller in the 1st OR Larger in the 1st (alternate days) Avoids many consecutive repetitions Pos 1-3 Difference ≥4 between pos1 and pos3 (larger - smaller ≥4) Many draws have a large spread Pos 2-3 Smaller in the 3rd position OR Larger in the 3rd (prioritize what is overdue) Closes the combination cycle Practical example: if in pair 1-2 the smaller is in position 1 → favor combinations where pos1 < pos2.

  Incorporating Hot/Cold/Medium into the crossover
  Main rule: Every combination must have at least:

  1 Hot digit
  1 Cold/Strongly Lagging digit
  1 Medium digit (or the third can be hot or cold)

  Good variations:
  2 hot + 1 strongly lagging digit
  1 hot + 2 lagging digits (when there are many "mature" lagging digits)
  1 hot + 1 medium + 1 cold digit

  Step 4 – Daily practical setup (realistic example)
  Assume today (your data):

  Strong lagging digits: 1, 4, 7
  Hot: 3, 8, 9
  Medium: 0, 2, 5, 6

  Late even/odd pattern: no PPP for 11 days → prioritize two or three even numbers.

  Low/high pattern: last one was AAB → prioritize BBA or ABB.

  Pairs:

  Position 1 < Position 2 (smaller in front)
  Position 1 and Position 3 difference ≥4

  Possible combinations (filtered examples):

  1 8 4 (late-hot-late | odd-even-even | low-high-low)
  4 9 0 (late-hot-medium | even-odd-low)
  7 3 2 (late-hot-medium | odd-odd-even)
  2 8 7 (medium-hot-late | even-even-odd)

  Play 8-20 combinations like this (Straight or Box depending on your budget).

  Final tips for improvement:

  Keep a notebook or spreadsheet with the 3 groups by position updated every day.

  Retroactive test: apply the strategy to the last 30 days and see how many hits you would have (it should hit 60-80% of the draws with 20-40 games).
  When a digit is very overdue (>15-20 draws), force it in at least 50% of the combinations.

  Alternate the patterns of the smaller/larger pairs every 3-5 days.

  That is mostly what my classifier script does. Displays the hots, colds and "neutrals".

  Slightly different implementation, but the same information. In each position it calculates a sample size by the formula (number of balls in the game, 10 for 0-9) x (number of times to give each number a chance to appear, I use 15) which for pick N games is 150 draws.

  The output shows the following information...

  [Number, frequency in the sample, classification (H, N or C), percentage of the frequency to the sample size, and the number of draws since it's last appearance.]

  Which might appear as 

  [0, 32, N, 11.2%, 35]

  Membership in the classification groups is based on the percentage to the sample size, such that if a number appears between the inter quartile range of Q2 to Q3, it is neutral, or N, below Q2 is Cold and above Q3 is Hot.

  The script is written to process this data universally per column on any game. It does not apply any filters, it is mainly used to present the classifications for use in filter creation as you have outlined above. Using a formula approach takes the guess work out of determining sample size and the use of the inter quartile range takes away any ambiguity of membership in the Hot, Cold and Neutral groups.

  What I had noticed in a sliding back test is that the most frequent pattern in the pick 3 is NNN, indicating the numbers tend to fill from the middle, a full 25% of all draws were NNN. the next 3 largest groupings contain 2 neutrals and 1 hot, as HNN, NHN and NNH. Lastly were neutrals with a cold, CNN, NCN and NNC. Any other combinations were so infrequent that they could be dismissed, particularly HHH and CCC. You might think that HHH would have done better, but it was not so.

  Have an EXCELlent day!

  Hello, Hiper, or anyone else who wants to create a spreadsheet, you have permission to use the cross-filter combinations, okay? There are people on the forum who understand Excel or Python who can use the post about cross-filter combinations if they want.

  Take the last 30–50 results from your Pick 3 lottery.
  Calculate the delay of each digit (0–9) at the current moment.
  Sort them as Short / Medium / Long.
  Use Excel, Google Sheets, or a lottery app to generate all 1000 combinations (000–999).
  Apply the filters above (logical conditions).
  Usually 80–300 combinations remain → play the box or go directly to the strongest ones.

  Delay groups are a solid defensive filter, but a poor offensive strategy.

  Okay, it depends on how it's approached and how it's cross-referenced with other filters, using a reference filter.
