Interactive 36-Outcome (6×6) Two-Dice Blot-Hit & Pip Calculator

TARGET DISTANCE: 6 PIPS

FAVORABLE ROLLS: 17 / 36 (47.2%)

Pick Distance to Opponent's Blot (1–12 Pips) to Highlight All Hitting Rolls (Direct + Combined):

Green cells in the 6×6 matrix hit the target distance! Notice why 6 away (17/36 = 47.2%) is the most dangerous blot distance.

Backgammon Combinatorics & Expected Value

The 11/36 "Rule of One Number"

Why do exactly 11 out of 36 rolls contain at least one specific number (like a 6)? Because Row 6 has 6 rolls, Column 6 has 6 rolls, and Double-6 (6-6) sits at their intersection: 6 + 6 - 1 = 11 (30.6%)!

Doubling Cube Take Point (25% Equity Threshold)

In a pure race without gammons, passing a double forfeits 1 point, while taking risks 2 points to win 2 points—meaning your mathematical Take Point is exactly 1 / 4 = 25% winning probability!
