Position Builder

Using Powerball as the example, lottery drawings do not assign white balls to fixed columns. LottoXray sorts the white balls from lowest to highest, then labels those sorted positions as C1, C2, C3, C4, and C5. Position Builder uses that structure so you can select a number for a specific sorted column.

A key number only needs to appear somewhere in the combination. A forced position is stricter: the number must appear in the exact sorted column you selected.

Analyze Last controls the historical distribution table. It lets you review a recent slice of the LottoXray database instead of always reading every stored draw at once.

On the free plan, this setting is locked. Paid plans can change the draw count, click Update, or use Max Draws to analyze the full stored database for the selected game.

In the Powerball white-ball math snapshot below, number 4 has 677,040 possible combinations in C1, 131,040 in C2, 6,240 in C3, 65 in C4, and 0 in C5. These values are total possible white-ball combinations by sorted column, not predictions.

This is the mathematical value of Position Builder as a filter: it shows when a choice is broad, narrow, or impossible. Forcing 4 into C4 is far more restrictive than forcing 4 into C1, but this only changes which games LottoXray can generate. It does not make the real lottery draw more likely to place 4 in any specific sorted column.

Once a forced position is applied, generated games must respect that sorted column rule. In the Powerball example below, number 24 stays in C4 in every game, with three white balls lower than 24 and one white ball higher than 24. The other white balls were generated randomly from the remaining eligible pool.

Position Builder creates games with a very high level of customization because it can send exact sorted-column requirements into Filter Builder. Instead of only asking LottoXray to include a number somewhere, you can decide which column that number must occupy before the games are generated.

Using Powerball as the example, a practical setup is to define up to four of the five white-ball columns yourself. That leaves one white ball for the generation process to select randomly from the remaining eligible pool, while the columns selected by the user stay fixed. The red Powerball number is handled separately from the five sorted white balls.
