Tunnel dice score when they form sequences that start with 1. Sequences are worth points equal to the sum of their faces. For example, a player with 1, 2, 3 scores six points (1 + 2 + 3).

Tunnel dice that aren’t part of a sequence don’t score. For example, a player with 1, 2, 4 scores three points (1 + 2). The 4 scores nothing because it isn’t in a sequence.

Sequences that don’t start with 1 don’t score. For example, a player with 2, 3, 4 scores nothing for those dice. Although they form a sequence, it doesn’t start with 1.

A player can score multiple sequences. A player with 1, 1, 2, 2, 3 scores nine points ([1 + 2 + 3] + [1 + 2]).

A single 1 is considered a sequence even though it’s only one die. A single 1 is worth one point. A player with 1, 1, 1 scores three points for those dice.

Sequences can’t “fork.” Say a player has 1, 2, 2, 3. That’s worth six points. The 1 can only be part of a single sequence, which earns that the second 2 isn’t part of a sequence that starts with 1, and so can’t score.
