Opposed die race
Choose which runner to move while balancing stack protection and exact finishing.
Logic & rule checking
- Players
- 2 players
- Time
- 12–20 minutes
- Materials
- A twelve-cell track, three counters each, one die, two waiting areas.
Prepare
Number one shared track 1–12. White starts with three runners before 1 and moves upward; black starts beyond 12 and moves downward. The waiting areas are not track cells. A runner finishing goes to its own finished box and never returns.
Play
White takes the first turn. Roll once and move one runner the exact number. Enter white onto the rolled number; enter black onto 13 minus the roll. You may pass only when no legal move exists. An opponent’s stack of two or more blocks landing, but may be passed over. Landing on one opponent returns that runner to its waiting area. Own counters may stack without limit.
Worked example
White at 4 rolls 3 and lands 7. If black has one runner at 7 it returns to waiting; if black has two at 7 the move is illegal. A white runner at 10 finishes on a roll 3, reaching the off-track 13. A roll 4 would overshoot and is illegal for that runner.
Finish and check
White finishes exactly at 13; black exactly at 0. The first to finish all three wins. Other runners may still be waiting when one finishes: this is not the all-in-home rule of backgammon. If neither finishes after sixty turns each, more finished runners wins, then record a draw if equal.
Adaptation and limits
Use a die or six equally sized numbered slips drawn and replaced after each turn. Record rolls when learning. The game borrows broad race/hit ideas but uses our linear rules; it does not reproduce a federation backgammon ruleset or guarantee balanced odds.
Purpose, observation and provenance
Within this activity: Choose which runner to move while balancing stack protection and exact finishing.
Check a die move as one exact step count; do not skip an occupied stopping cell.
Our rules, examples and printable diagrams are separately prepared. The earliest inventor of the broader mechanism is not established here.
