How the dice work
The server generates every roll independently.
Six equally likely sides
The game uses the operating system's cryptographic random number generator. Its mapping to values 1–6 rejects values that would otherwise favour some sides. Each die is drawn separately.
Your browser cannot choose the roll. Score, rating, advertising, previous rolls and bot difficulty do not influence it. A double six has a probability of 1 in 36 for each two-dice roll, regardless of what happened before.
Refresh preserves the roll
The current dice stay in the room state until the turn finishes. Refreshing or reconnecting does not grant new dice. The computer opponent must use the same server dice and legal-move checks as human players.
