Last rolls
The dice come from your browser's cryptographic random generator: bytes 252–255 are thrown away and each remaining byte becomes byte % 6 + 1, so every face is equally likely. Nothing is sent anywhere. For games against other people, TavlArena also seals the dice before the game so you can check them afterwards: see fair dice.
Odds for two dice
| Result | Ways out of 36 | Chance |
|---|---|---|
| A particular double (for example 6-6) | 1 | 2.8% |
| Any double | 6 | 16.7% |
| A particular mixed roll (for example 6-5, either way round) | 2 | 5.6% |
| At least one die showing a given number | 11 | 30.6% |
| Hitting a blot 6 pips away (direct 6, 5-1, 4-2, 3-3, 2-2) | 17 | 47.2% |
The last row is why distance matters: a blot 6 pips away is hit by any 6 (11 rolls), by 5-1 and 4-2 (4 more), and by 3-3 and 2-2 (2 more), if nothing is in the way.
