Backgammon: Pips & Odds

Backgammon: Pips & Odds

Pips count the distance your checkers still need to move.

A lone checker shows how many of 36 rolls can hit it.

We count all 36 possible rolls and every legal opponent play on the current board. Empty-board tables can differ: blocked landing points stop indirect hits. These percentages describe one roll, not the rest of the game.

A visible seed and roll index reproduce the same dice. We count observed and expected results for all 21 combinations. The opponent never sees future rolls; difficulty changes position judgement, never dice. Counts help inspect fairness, not explain a loss. Small samples can be uneven; hundreds of rolls are needed to settle.

In a pure race, pip counts estimate winning chances and guide doubling. While contact remains, this game does not advise on the cube: it does not run the rollouts needed for reliable advice.

The engine chooses from legal plays. It is not a neural network or world class. Levels change how it values exposed checkers and how far it plans ahead.

Standard rules: doubling cube, gammons, backgammons and Crawford in match play. Use both dice when legal, or the larger die if only one can be used.
