The 3.5–11–6 Unified Diamond System

One Diamond Numbering System for One-, Two-, and Three-Rail Shots. Same table. Same diamonds. Same numbering. Different calculation.

The 3.5–11–6 Unified Diamond System was developed by Yuriy Setko as part of the Diamond Deck / Pool Practice Cards training ecosystem. It brings one-, two-, and three-rail shot methods under one consistent diamond-numbering convention.

Why Another Diamond System?

One bank system used one set of numbers, a kick system used another. Keeping all of them straight in a real game was the problem. The methods were translated into the same numerical language and organized around one consistent convention — the Diamond Numbering System.

One Table. One Numbering Language.

Long rail 1 through 8, short rail 1 through 4, read relative to the player’s orientation.

Meet 3.5 – 11 – 6

  • 3.5 — one-rail method
  • 11 — two-rail method
  • 6 — three-rail method

The calculation changes depending on the route. The underlying diamond numbering does not.
